Farewell to the hustle and bustle of the city and enter the experimental field for rice transplanting

June is the annual seedling planting season. Parents and families accustomed to city life enthusiastically signed up for this activity and came to the Zhuangxing Comprehensive Experimental Station of the Shanghai Academy of Agricultural Sciences in Fengxian District to get close to nature and visit the experimental field in the atmosphere of agricultural scientific research. , Agricultural greenhouses, laboratory buildings.

To commemorate the “Father of Hybrid Rice” Academician Yuan Longping, this science night specially planned the “Parent-Child Fun Rice Planting” session. Although it was raining, under the guidance of professional scientific research teachers, he rarely did farm work on weekdays, or even did it. Parents and children in the field are enthusiastic, sow their own rice seedlings by themselves, get close to the green and work hard, experience the magical vitality of seedlings, and learn about the difficulty of food research and development, production, sowing and harvesting.

After experiencing the hard work of the field, and seeing the process of rice turning into rice, the children can taste the taste of the latest rice and corn cultivated in Shanghai. At the site of the Zhuangxing Comprehensive Experimental Station of the Academy of Agricultural Sciences, in order to celebrate the 100th anniversary of the founding of the Communist Party of China, a large-scale colored rice field with a length of 200 meters and a width of 100 meters was specially designed and planted, and the participating audience was invited to take photos with it. The audience participating in the event also met the breeders from the Municipal Academy of Agricultural Sciences, listened to the story of rice growth, and learned about the mentality of scientific researchers.

The development of “little breeder” in the Quest Lab In the afternoon and night events of this science night, a fun science interactive session was set up to develop a “little breeder”. Participants were invited to enter the Fengpu campus of the Shanghai Academy of Agricultural Sciences to explore the secrets of crop breeding and cultivation. Institute, communicate with researchers and laboratory science breeders. The site will be equipped with a microscope to observe the microscopic world, experiment with species, learn the use of centrifuges, experience rice DNA extraction and other scientific experiment interactions. Teenagers will be invited to complete scientific tasks, learn laboratory knowledge by themselves, and become children through understanding basic scientific research. Little agricultural scientist!

The spirit of a scientist, to perceive the mystery and splendor of science. Dongfang.com reporter Cao Lei reported on June 21: Braving the heavy rain, he walked into the experimental field to plant seedlings, clocked in the large-scale colored rice fields, explored the laboratory to complete scientific research tasks, learned about the latest corn, grain, oil, vegetables and fruits cultivated in Shanghai, and cherished the enthusiasm for science. To commemorate Academician Yuan Longping and thank the scientific researchers for their hard work and cultivate the scientific awareness of young people in loving food and saving food. Focusing on the theme of “holding the rice bowl firmly in one’s own hands”, the 2021 Science Night recently held a special event at the Municipal Academy of Agricultural Sciences.

According to scientists, the reason farming has to use Neonicotinoids is to combat the many predators that are ready to pounce on corn or soybean seeds, every time they are sown in the ground. Seeds are impregnated with drugs before sowing. Photo: Scientific Beekeeping What are neonicotinoids? Neonicotinoid has been banned for use in Australia and Europe since 2013. This is a pesticide derived from nicotine (the addictive substance found in tobacco), the way to use is to dissolve in water and spray on plants. for the plants to absorb themselves, forming an artificial “immune system” to protect the crops. Neoincotinoids are thought to be effective against pests and insects, but are safe for mammals. However, because of its strong effect on insects, it also affects bees directly, reducing the number of pollinators. This pesticide is said to reduce the sperm count of male bees by up to 40%, as well as reduce their lifespan from an average of 22 days to 15 days, thus reducing the chances of male bees fertilizing the queen bee. also decreased. Besides disease, soil-dwelling pests such as helminths and larvae can also damage seeds and seedlings, along with terrestrial insects such as bean leaf beetles and aphids. seeds and saplings. Therefore, in the field of seed treatment against insects and diseases, farmers often treat seeds in combination with fungicides (IST) to help plants sprout straight and grow early. It is easy to mention some of the popular Neonicotinoid IST methods such as Imidacloprid (Gaucho, Bayer Crop Science), Clothianidin (Poncho, BASF) and Thiamethoxam (Cruiser, Syngenta)… Seth Naeve, an agronomist specializing in soybean research at the University of Minnesota Extension (USA), said that Neonicotinoid insecticides are highly water-soluble, helping to activate protection from insects. Great early season. Shawn Potter, Syngenta’s head of seed care product marketing, said that the growth of the seeds after treatment was driven in part by previous seasons. “Early seeding from a wet, cool, or both, seeds and seedlings will be exposed to various diseases. “Without seed treatment, crops could be damaged early on,” said Mr Potter. Nick Tinsley, BASF technical specialist, added: “Farmers and retailers alike can easily treat corn and soybean seeds with Neonicotinoid insecticides as well as fungicides from the company. producers to protect crops”. For decades, seed companies have treated corn with fungicides. However, IST only started to be added to the fungicide seed treatment of soybeans in the early 2000s. Studies have demonstrated that a combination of seed treatment with both fungicides and insecticides increases soybean yield per acre by 2 bushels (equivalent to 72.74 kg/0.4 ha). According to Mr. Potter, in general, each “shift” of treating soybean pest/mushroom combos will cost from 10 to 12 USD per seed unit (ranging from 80,000 to 140,000 seeds/0.4 ha). That’s because 70% of treatment costs go to pesticides, while the profit-taking rate per acre is between $16 and $17. This assumes that soybeans cost $12 per bushel and that the cost of the pesticide seed treatment is between $7 and $7.50 per seed unit. Entomologists in the Midwest and South America have also observed that the average soybean yield spike of 2 bushels per acre from this combination. “Some years are higher, some years are lower,” says Sebe Brown, an entomologist at the University of Louisiana. Responses tended to be higher in cases where soybeans were planted early, two crops, or planted after a cover crop.” Gus Lorenz, a scientist at the University of Arkansas, adds: “Companies have provided growers with insurance to maintain good standing. At current seed prices, the cost of treating seeds with pesticides is a good investment.” A synthesis of studies in a 2019 report representing agronomists and entomologists from 14 universities found that the best recorded soybean yield was an increase of 3.3 bushels per acre. after using the combined seed treatment solution. However, in some cases in Minnesota, the benefits are so small that it is argued that farmers should not be encouraged to use seed treatments or should apply them selectively. Concerns Previously, scientists believed that neonicotinoid pesticides were the main cause of the decline in bee populations and pollinators worldwide. A few years ago, the United Nations published alarming figures: In the first 10 years of the 21st century, the number of bees in the world has decreased by 85% in the Middle East, about 30% in the US and Europe. Neonicotinoids are likened to “birth control pills” for bees and reduce the population of bees. Photo: GCM Bees are the intermediate species that help pollinate more than 75% of the world’s food and fruit crops, so a decrease in the number of bees also means a reduced crop or even a crop failure. However, long-term studies by Syngenta suggest that the health effects of bees are negligible when using Neonicotinoid seed treatments to kill insects. According to Mr. Potter, what many experts agree on is that the health of bees depends on the interaction of factors such as parasites, disease, nutritional health and weather phenomena. A 2019 study published in the journal Scientific Reports detailed the effects that imidacloprid had on white-tailed deer. When imidacloprid (an insecticide that acts as an insect CNS toxin, belonging to the genus Neonicotinoids) was increased in the animal’s spleen, factors such as progeny viability, length of jawbone, body weight and visceral weight all decreased. Records show that at least 60% of white-tailed deer killed indicate the presence of Imidacloprid. According to expert Jonathan Lundgren, all insecticides can negatively impact mammals and bees. “The use of insecticides is so widespread these days that they are present in almost every growing system across the United States and are truly binding. These insecticides are affecting ecosystems in ways that we could not have foreseen.” Meanwhile, the companies that manufacture and trade in Neonicotinoid seed treatments have always denied this and asserted that “the products are safe if used according to the instructions on the label”. Compounds such as polymers coat the seeds or products like Bayer Fluency Agent Advanced to help prevent release into the environment, said Chip Graham, Bayer Crop Science’s North American director of seed development. “Initially we had really low dust levels, but these products ensure that pesticides remain on the seeds and reduce contamination levels during the growing process,” said Mr. What is the future of farming? Instead of treating seeds with neonicotinoid insecticides, Mr. Lundgren called for regenerative methods, such as tilling and changing seasons, increasing crop diversity as well as reducing pest pressure. bugs, insects. “Farmers need to understand that these seed treatments really don’t help them much,” said Lundgren. Neonicotinoid pesticides are believed to reduce bee pollinators, threatening food security. Photo: TN Meanwhile, expert Graham said that banning this seed treatment would be detrimental to farmers because “there are currently no foliar sprays to treat early-season insects as a rescue application”, so ” Seed treatment in this way is most effective to provide activity against early-season pests of maize and soybean.” Agronomist Naeve said: “They’re a good example of how the best tools we’ve ever had in agriculture, but it’s not a good idea to treat the entire soybean acreage. They can be a double-edged sword.”

According to what plant scientists at the Missouri Botanical Garden (USA), the tiny purple-white flower that has just bloomed in their greenhouse has never been seen, at least by experts like them. In early May, Justin Lee, a gardener, was inspecting a group of Karomia gigas seedlings when he discovered a strange flower. This plant is related to mint and is native to Africa and is one of the endangered plants. Strange flower varieties Giống This flower less than 3cm long has pale purple ring-shaped petals, which slope down to form an arch connected to four white petals, with outstretched pistils. Mr. Lee said: “It doesn’t look like a mint flower. It looks like it’s upside down.” The mint family, Lamiaceae, usually has funnel-shaped flowers. Caregivers think the flowers may attract bees, butterflies and moths, but they may also be self-pollinating. Over the next few weeks, they expect more Karomia gigas flowers to bloom in the greenhouse, and instead of attracting insects, they will attract human hands trying to keep the species from extinction. When more flowers bloom, plants can cross-pollinate and have an extra chance of survival. Currently, only about 20 individuals of Karomia gigas are known in the wild in Tanzania. Roy Gereau, Tanzania project leader at the Missouri Botanical Garden, said it’s not uncommon for anyone to have seen flowers grow from this tree. Karomia gigas is a tall, straight-stemmed tree that can reach a height of 25 m, the branches grow about 13-14 m above the ground, making the flowers difficult to see. Karomia gigas is quite tall and is located deep in the forest. The tree is so rare that it does not have a common name in English, Swahili (the main language of Tazania) or the dialect of the area around the reserve where the tree was found. Of the more than 60,000 known tree species on Earth, Karomia gigas is among the most threatened and endangered in Africa. “As far as we know, there is no scientific record of the flower of this plant,” said Gereau. And now, when the trees bloom, conservationists believe they can keep them from disappearing. “In terms of extinction, this is a really, really good sign. We can make sure this plant doesn’t go away,” said Andrew Wyatt, vice president of horticulture at the Missouri Botanical Garden. There is still hope Growing this tree is a challenge. In the wild, Karomia gigas is highly susceptible to a fungal infection spread by insects. In September 2018, thousands of seeds were collected in Tanzania and brought to St. Louis, but only 100 seeds can be used for germination. The nursery also had to adjust soil texture, water availability and sunlight to mimic the East African environment in which the plants grew. Gardeners are finally able to grow the plants by letting the seeds germinate on wet paper towels (reducing the risk of infection), and then planting them in the potting soil. Currently, they have about 30 seedlings from seeds and one from cuttings. Creating a growing environment for this species is very difficult. “We’re debating whether they can bloom in a caring environment,” Mr Wyatt said. When there are only a few trees of this species left in the world, trying to save them and seeing them grow successfully is very emotional. “You will cherish every stage. They are like your children. You are like the housekeeper of these plants. You not only have a scientific connection, but also a love for them” – he Wyatt shared. Mr. Lee agrees: “They are like my children.” The flower helped scientists understand more about the plant, verifying it was classified correctly, and the shape suggested it was most likely pollinated by an insect. To date, they have not been able to tell if this flower structure is common to the species, or just a genetic mutation in the still young plant. “This single flower … may not be the usual flower form of the tree. This is the first flowering tree of fortune telling” – Mr. Gereau commented. The first flower was recorded. Most importantly, this helps ensure the survival of the tree. Botanists can take cuttings to propagate, but they will share the same DNA. Having genetic diversity will help ensure that plants can withstand harmful elements such as pests. “If crops don’t bloom, we have to depend on wild plants for seeds, and their survival is very low,” Wyatt said. While some species are able to self-pollinate, it is not clear whether Karomia gigas does. Mr. Lee tried pollinating before the flowers died, but said adding flowers from other plants would help create a new generation of plants that are genetically more tolerant. “I’ve chalked the flowers. But so far the self-pollination is still a big question mark. And this time we didn’t succeed. However, we have many seedlings left, if they bloom and pollinate. Cross-pollination is better for genetic diversity.” “Having a tree in bloom is a great start in a species recovery effort,” says endangered tree expert Emily Beech. Although not involved in the tree planting process in St. Louis, in 2016, Ms. Beech and Mr. Gereau and rangers searched for this tree in Tanzania. “When we got there, we didn’t see any sprouts in the forest, but the blossoming tree shows that there is still hope for this tree in the future,” she added. One step closer to reinvention Karomia gigas was discovered in 1977 in Kenya. When the last two trees here were cut down, scientists thought the species was extinct. Then, in 1993, several trees were discovered in Tanzania. From 2011 to present, Mr. Gereau and Tanzanian botanists have found more individuals in the wild. According to Mr. Fandey Mashimba, head of the seed department of the Tanzania Forest Service, about two dozen Karomia gigas trees still exist in the wild, in two forest reserves Mitundumbea and Litipo. These two reserves have the Miombo forest ecosystem – common in Central and South Africa. This is the habitat of wild animals such as gorillas, wild boar, wild buffalo and a small antelope called Dik-dik. While individuals studied in the native environment and one growing in St. Louis, their flowers are still a mystery. “We have a person in the nearest village to the reserve, he keeps an eye on them and will notify us when he notices the plants are about to flower,” said Mr. Gereau. However, when someone drove the long way through the forest and reached the tree, no flowers were found. “They’re in a reserve protected by the government, but a lot of people go there to get wood,” Mashimba said. The wood of Karomia gigas is compared to teak – a precious wood, so they have a high value. “We have trees that are still alive. We can make sure they don’t go extinct. Successful conservation of this species is possible. They are protected in Tanzania. We have a bunch of trees in the botanical garden. When we have enough seeds, we can store them in case.” Seedlings are cared for at the Missouri Botanical Garden, USA. Gereau said he does not want to transfer the plants yet, fearing they are too fragile to make it through the trip between the two continents, but his team will actively share knowledge with the Tanzanian government and botanists at the University of California, San Francisco. University of Dar es Salaam, which is conducting research on this plant. For now, a flower is a hopeful sign of what’s to come. The staff at the botanical garden at St. Louis was surprised when it quickly fell from the tree in less than 24 hours. “It withered and fell. I picked it up and used it as fertilizer,” said Mr. Wyatt.

Group of young people in Dak Lak making seed bombs In early 2021, this group of young people changed the color of cleared lands, bare hills, grasslands and forests by wrapping the seeds with clay, helping to protect the seeds from being eaten by insects. and when it rains. The soil cover will retain enough water for the seeds to germinate. Nuts are prepared by the group to make a seed bomb The way to do it is just to keep, wash and dry the fruit seeds… create a “seed bomb” – mix clay, humus with manure and a little water, knead it by hand, then give the seeds to plant. in the middle and then roll it up. Next, the “seed bomb” was placed by young people in the vacant land, the wasteland where they lived and passed. “Seed bombs” grow according to the principle of nature, they germinate when it rains, without fertilizing or watering. A bomb has five kinds of particles According to Mr. Pham Thanh Tuan (the initiator of making “seed bombs”), there are 5 types of seeds in 1 bomb: pioneer trees, canopy trees, nitrogen-fixing plants and low-level medicinal herbs. After the seedlings have grown, a sufficient amount of nutrients is available as compost mixed with the soil for the initial growth of the plant. The rainy season lasts 2-3 months, enough for strong seedlings, when the dry season comes, the resistance of seedlings is also stronger. Mix clay, manure, water, humus as seed cover Thanks to the compactness of each “seed bomb”, even the dry season can be carried to an area suitable for the growing conditions of each cultivar contained in the bomb. According to Mr. Tuan, using “seed bombs” helps to overcome difficulties in climate conditions as well as save manpower and costs for afforestation. “Seed bombs” can take advantage of endemic trees regenerated by seeds, with high drought tolerance to develop natural forest areas.

During the anti-American war to save the country, many soldiers had to eat rotten vegetables to fight hunger. Dimpled vegetables grow a lot in coastal areas, along rivers and canals. Previously, people freely picked dented vegetables in the sea and sold them. However, for about a decade now, when dented vegetables have been favored by the market, the owners’ beaches have been protected, people are not free to come and pick this wild vegetable anymore. In order to actively source dented vegetables to sell to the market, and before the natural amount of dented vegetables is increasingly depleted, many farmers have organized to plant dented vegetables. Taking advantage of canals and ditches in the garden, farmers pluck wild rotten vegetables from the sea to plant. Currently, in Ho Chi Minh City, vegetables are grown mainly in Bon Phu hamlet, Trung An commune, Cu Chi district. Mr. Nguyen Van Thanh (Bon Phu hamlet), leader of the commune’s vegetable cooperative, shared in Nhan Dan newspaper: “Over the past six years, I have expanded the ditch to bring water from the Saigon River into the family’s fruit garden, then pick rotten vegetables that grow wild and transplant them in the same way as rice transplant.This guy (meaning vegetables) must be planted under another tree to create shade, tolerate fresh water from the river, and adapt to Trung An’s soil, so more seedlings will grow quickly So, my family’s average income from dented vegetables is 250 million VND/year. Seeing that I’m doing well, relatives follow suit, so I’m the “boss”!”. And no longer self-harvesting as in the past due to the growing area, Mr. Thanh asked more farmers in the hamlet to collect daily. Since then, that creates more regular jobs for eight workers per year. To grow dented vegetables, people dig wide ditches to direct water from the canals. Planting method is like sowing seeds, just plug the seedlings down and let them grow on their own, without much care. After one year of planting, it can be harvested. When harvesting, only young shoots are taken. Each stalk is 30-40cm long. Because the dented leaves grow quickly, they have to be picked every day to avoid getting old. The old leaves of the vegetable have many sharp thorns in the middle of the stem, so the picker must always wear long-sleeved clothes, gloves to avoid scratching the skin. When picking vegetables, go along each row so as not to miss young shoots. This job does not require a lot of skills, but it takes endurance and quick hands to wade through the water continuously for a few hours to pick vegetables. For each pound of vegetables, the gardener is paid 6,000 VND. Currently, in Trung An commune, there are still a few dozen people picking wild vegetables. Currently, the price of fresh rotten vegetables is always around 25,000 VND/kg, silage reaches 40,000 VND/kg. Farmers with a water surface of about one thousand m², growing dented vegetables can harvest 150 kg / week, so if they sell fresh vegetables, they also earn 15 million VND / month and this “sales” is even. all year round. As for a person who owns 2.5 hectares of dented vegetables like Mr. Vo Van Horn, every day he picks more than 50 kg of dented vegetables every day, with the current selling price, except for picking he earns nearly 2 million . The young shoots of dented vegetables can be used to process many dishes such as eating raw, squeezing salad, boiling, stir-frying, cooking sour soup, dipping hot pot… (According to GiadinhNet)

Daedong Ganoderma products have luxurious packaging. It is known that Daedong is a premium red ginseng brand sponsored by the Korean government, with extensive experience in the production of ginseng products, cordyceps and reishi mushrooms. Daedong’s products are popular in the domestic market and exported to dozens of countries, including Vietnam. Meanwhile, Imsil district in Jeollabuk-do province is a famous Korean reishi mushroom growing place. This place has special climatic and soil conditions suitable for this precious mushroom species, besides the people’s experience in mushroom cultivation is handed down as a long-standing tradition in the locality. In Imsil, the highland terrain is still relatively unspoiled due to the lack of industrial parks, cool climate, and natural clean water. With the participation of Daedong Corporation, many modern technologies are applied to support mushroom cultivation on the basis of preserving the maximum purity of nature. To shape products in the high-end segment, Daedong Group chooses oak tree trunks as the initial growth medium for Ganoderma lucidum. The trunks are carefully selected, are healthy, disease-free, uniform oak trees. The trees were disinfected for 48 hours with heat, then “rested” for about a week before being used as a place to inoculate reishi mushroom spores. From January to March, when the climate is most suitable, experienced Imsil farmers manually inoculate the oak tree with fungal spores. Then all are placed in a temperature and humidity controlled environment. The fungal sporulation phase takes place for 70 days, the oak stems are brought to the ground, the mushroom seedlings begin the development process. From seedlings to adults that are slightly larger than a hand, Daedong Ganoderma lucidum is located in a closed farm to ensure control of environmental indicators such as temperature and humidity. Daedong Ganoderma lucidum is grown on oak tree trunks placed under the ground in the famous Imsil mushroom growing area in Korea. When the fungal spores have developed into seedlings, the oak stems are buried in the ground. Experts of Daedong Group together with Imsil mushroom farmers continue to strictly control the growth environment of mushrooms until the mushrooms are mature and ready to be harvested. The whole process of mushroom development, many modern agricultural technologies are applied but always ensure environmental friendly factors, absolutely do not use pesticides or additional artificial nutrients. When Ganoderma matures, the size of the mushroom is slightly larger than the hand, uniform in shape due to being cared for according to the traditional secret of Imsil farmers. After being harvested in the field, Ganoderma lucidum will be dried and disinfected with Daedong’s own technology for long-term preservation, before being packaged into finished products without using any preservatives. Rest assured of origin, quality The new Daedong Ganoderma lucidum product is imported and distributed in Vietnam by the importer VHP – a reputable company for more than 10 years in the field of importing and distributing Korean health products and an exclusive partner. Daedong’s rights in the Vietnamese market. Ganoderma lucidum has long been famous as a benign herb for daily use, with the effect of enhancing resistance thanks to its high content of polysaccharides. Therefore, in recent years, Korean Ganoderma lucidum is interested by Vietnamese consumers to buy a lot for use and as gifts. However, the fact that Ganoderma lucidum on the market is mostly unorthodox products, leading to the situation of counterfeit goods and poor quality products being mixed. With the goal of serving long-term consumers with high quality products, Daedong Ganoderma lucidum is officially imported, certified and quality inspected by the National Institute of Food Safety and Hygiene. Before coming to Vietnam, Daedong Ganoderma lucidum was also certified for origin and quality standards by the Korea Food and Drug Administration (KFDA). “As a prestigious corporation that manufactures and trades in human health-related products in Korea, Daedong wishes to bring to Vietnamese consumers an authentic and fully tested reishi mushroom product. enough by Vietnamese and Korean authorities, helping consumers to choose with peace of mind.” , said Mr. Choi Sung Keun, Chairman of Daedong Group.

Technicians of the Center for Radiation Technology and Biotechnology (Nuclear Research Institute, based in Da Lat city, Lam Dong) next to a radioactive projector that causes mutations in plants. The Center for Radiation Technology and Biotechnology (Nuclear Research Institute) is a unit that regularly applies radiation techniques to select and create mutant varieties on plants. Especially in the past time, the orchid and bonsai market has been extremely active, many customers have come to the center to irradiate to mutate their plants. The irradiation process is quite quick, with the new technology Gama Cobalt irradiator, this process only takes about 1-2 minutes and is completely automatic. Immediately after, orchid seeds will be taken to the separation room to be cultured in nutrient solution for a certain time. After that, these plants were further isolated many times to select mutant morphologies different from the parent plant. Master Le Xuan Cuong, irradiation technician (Center for Radiation Technology and Biotechnology), said that the number of doses will vary depending on the sample provided by the customer such as tissue samples, branches, seedlings… “After irradiation, it will produce random mutations, beneficial or harmful, regardless of their will” – Master Cuong said. Currently, the Center’s Culture Room is storing many pseudo-crane orchid seedlings that have mutated on the stem and on the leaves. Specifically, the color of leaves and stems have turned white or purple. These are mutant forms that can be seen immediately, for flower color, you have to wait for the plant to grow and flower as usual. According to Mr. Le Van Thuc, Deputy Director of the Center for Radiation Technology and Biotechnology, for flower plants, by irradiation techniques, it is possible to select flower colors or select traits that are resistant to adverse conditions. environmental benefits such as preventing fungal and bacterial diseases on plants. “Compared to natural mutations, the probability is one in a thousand or one million, but using radioactive sources to cause mutations in plants will have a higher probability of hundreds, thousands of times,” – Mr. Thuc analyzed. Application on many plant varieties After irradiation, samples of the fake crane orchids were taken to the separation room to be cultured in nutrient solution for a certain time. Not only orchids, the Center for Radiation Technology and Biotechnology has tested irradiation to cause mutations on Forget-me-not Da Lat flowers, Torenia flowers, and Dendrobium orchids. The results have created many mutant lines in flower color and structure of stems and leaves with great differences compared to the mother plant. Through that, the Center has built up the basic processes of radiation breeding; selection of materials for irradiation, frequency of irradiation, propagation, experimental planting to screen for mutations at phenotypic level, identification of mutant lines at molecular level… According to Mr. Le Van Thuc, the Center’s orientation will continue to promote the field of plant biotechnology and plant breeding, rapid multiplication of plant varieties and conservation of valuable plant genetic resources; continue to develop radiation technology in the selection and breeding of key plant varieties, endemic varieties of Lam Dong province, focusing on selecting and creating new quality varieties on flower, fruit, ornamental and medicinal plants. The culture room of Radiation Technology and Biotechnology (Nuclear Research Institute) houses many mutant plants, which are mainly orchids. Currently, the Nuclear Research Institute has used irradiation techniques combined with In-vitro methods, applying in vitro flowering techniques to quickly select flower color mutations, shortening the selection time. filtering, reducing the cost of isolating mutant lines that previously had to be planted in the field for selection. At the same time, the Institute cooperates with many units throughout the country such as the Southern Fruit Institute, the Mekong Delta Rice Institute, the Central Highlands Agro-Forestry Research Institute, universities: Tra Vinh University, the University of Da Lat,… to handle mutant irradiation on many different crops. Mr. Do Minh Ngoc, Deputy Director of the Department of Science and Technology of Lam Dong province, said that irradiation is a tool and a technological solution for breeding that many parts of the world have implemented. However, the selection and maintenance of mutant traits is very important and requires time and experience for these plants to become a source of seeds for other production industries.

Orchid nursery nursery Di Linh – the result of the project of breeding In-vitro fake crane orchids by the Center for Science and Technology Application (under the Department of Science and Technology of Lam Dong Province). The technique of propagation by plant tissue culture (In-vitro) is no longer strange in Lam Dong province in general and Da Lat city in particular. The application of this technology to propagate the species of Orchid Di Linh was first deployed by the Center for Science and Technology Application. The project was completed, completed and accepted by Mr. Phan Quoc Chinh, Deputy Director of Lam Dong Center for Science and Technology Application and his colleagues. To select the original source of quality seed, the people who carried out the project had to collect Gia Hac Di Linh orchids in Da Lat city and Di Linh district, in orchid gardens that met strict standards. Sampled plants must have an average height of 30-40 cm, have 14-16 pairs of leaves, average trunk diameter of about 4mm and be planted in plastic or terracotta pots. Each tree has 4-5 fruits and the physiological ripening rate is not equal. Selected fruits that should be dark green and physiologically ripe, of the specified size, without cracks, were collected for inclusion in the sample. After cleaning and disinfecting, samples of Di Linh falcon will be propagated in-vitro according to the following summary procedure: Initial culture stage to create buds and clusters of buds; rapid multiplication stage; rooting stage to create a complete plant. These three stages take about 28 weeks, then the seedlings (5cm tall, 4cm long roots, good growth, dark green leaves) are brought to the nursery to plant and take care of. After about 24 weeks, the plant can be grown with a height of 5-7cm, with 4-5 leaves. According to Mr. Phan Quoc Chinh, plants grown in an In-vitro environment must ensure the conditions of temperature, humidity and light intensity according to certain cycles. In addition to the results of creating a series of fake crane orchids, the project also built a standard process for propagating this plant by the In-vitro method and can be transferred to other units. “During the implementation, we tried to add ripe banana pulp, coconut water to the culture medium. The results showed that shoot formation and shoot growth also increased faster than normal, “- Mr. Chinh said. Very cheap price Seedlings of Phalaenopsis orchids are extracted and put into nutrient bags to be raised in the laboratory before being sent to the nursery. After completing the In-vitro propagation process, the first 500 orchid seedlings were brought to the nursery at the Don Duong Experimental Station (Don Duong District) and continued to be tested on many different types of media within a short period of time. 3 months. As a result, the rate of plants living outside the nursery reached 90%. Among the types of substrates put into the experiment, the coir fiber medium helped the plant grow best, the height of the tree reached 5.6 cm; The root length is 3.70 cm, the survival rate is 95% and the tree has a large stem, dark green leaves, many leaves. According to Mr. Nguyen Nhu Chuong, Director of Lam Dong Center for Science and Technology Application, after the acceptance of the project, the Center continues to propagate about 3,000 plants to supply domestic and foreign markets at an export price. selling for only about 25,000 VND/seedling. “The method of tissue culture in the laboratory makes it possible to propagate many times larger numbers than natural breeding. Therefore, the price that the Center is selling to the market today is normal,” said Mr. Chuong. From the research results of the topic, Lam Dong Center for Applied Science and Technology has developed a baseline standard for the Di Linh Giac Giac orchid seedling and was continued by the Sub-Department of Cultivation and Plant Protection. take. Thereby, the genetic resources of rare forest orchids originating in the locality are preserved and developed. A Di Linh Fake Orchid is eligible for sale for 25,000 VND / tree, very cheap compared to the current market. According to Mr. Ho Anh Dung, Vice Chairman of Da Lat Flower Association, the quality of In-vitro seedlings will ensure higher uniformity and superiority compared to traditional methods, serving the conservation of seed resources. and commercial purposes. The first-line mother tree has been carefully selected, which will help the seedlings to preserve the best characteristics of the mother plant, not only the Di Linh orchid but also precious plants such as Ngoc Linh ginseng, Camellia flower .. .

After irradiation, samples of the fake crane orchids were taken to the separation room to be cultured in nutrient solution for a certain time. (Photo: Nguyen Dung/VNA) In Lam Dong – the “capital” of high-tech agriculture of the country, the application of new science and technology in agriculture is increasingly widespread. Especially for the plant breeding industry to preserve rare genetic resources as well as to develop commercial varieties of these plants. Wild Orchid Di Linh is one of such trees. They are not only mass-produced, but also irradiated to create mutations on demand. Di Linh fake crane – a “famous” orchid of orchid players inside and outside Lam Dong province, often sought to buy with many different prices. However with In-vitro technology As modern as it is today, for the first time, the Center for Science and Technology Application (Lam Dong Department of Science and Technology) has successfully studied the process of mass propagation of this plant. Mass breeding The technique of propagation by plant tissue culture (In-vitro) is no longer strange in Lam Dong province in general and Da Lat city in particular. The application of this technology to propagate the species of Orchid Di Linh was first deployed by the Center for Science and Technology Application. The project was completed, completed and accepted by Mr. Phan Quoc Chinh, Deputy Director of Lam Dong Center for Science and Technology Application and his colleagues. To select the original source of quality seed, the people who carried out the project had to collect Gia Hac Di Linh orchids in Da Lat city and Di Linh district, in orchid gardens that met strict standards.

Each tree has 4-5 fruits and the physiological ripening rate is not equal. Selected fruits that should be dark green and physiologically ripe, of the specified size, without cracks, were collected for inclusion in the sample. A seedling of the fake crane orchid has had a mutation: the color of the leaves, the stem has turned white or purple.

Being passionate about plants and sticking to plant research, especially flowering plants, TS. Do Van Truong , Vietnam Museum of Nature, Vietnam Academy of Science and Technology, famous scientist for many discoveries for new species, dedicates his youth to focus on research in this field. TS. Do Van Truong on a field trip. Along with the professional work such as biodiversity research, plant resources … an important part of the TS’s indispensable work. Do Van Truong and colleagues to find and identify new species for science. And each new finding is published is a special story with lots of sweat and tears. TS. Do Van Truong recalled that in 2017, when he was on a field research trip in Kom Tum, he was on his way back to Nha Trang and happened to be surfing on Facebook and saw a young friend posting a picture of a tree wildly. See photo, TS. Do Van Truong saw that this was a very strange tree, never seen before. Immediately exceed 200 km to enter Binh Dinh area and approach strange trees. Arrived, TS. Do Van Truong received guidance from a local resident and confirmed that it only took half a day to both go and return. So at 10:00 a.m. the group set off with their inventory of a few loaves of bread for a makeshift lunch in the woods. As expected, about 2 hours later, we have reached the place where there are strange trees. The team was very happy and spent an hour observing, describing, recording, and collecting samples of strange plants to study. Due to the fact that indigenous people have a clear understanding of the terrain in the area, the group decided that when they returned, they would not return to the old road but approach another forest area to find a trail back to the village. However, the more you get lost. 5:00 pm, darkness collapses, only 2 small biscuits left, the phone has no waves, cold weather and small rain. The group decided to stop and approach the nearest mountain to hope for phone waves, because according to many years of experience in the jungle, TS. The more you know, the more you get lost and lose your energy. Hunger, cold, and even panic occasionally rekindled. 5am ​​the next morning, TS. Do Van Truong and his colleagues decided to go back to the old way. The group went continuously for 5 hours to reach a large stream flowing back to the village and met two communal militiamen who were on a mission to “find stray scientists”. As it turned out, during the night, many of the people in the village were unable to sleep because of their anxiety. The police, the military, even professional hunters were mobilized to find you. “It was a memorable trip in life. Hungry, thirsty, arriving in tattered clothes. Luckily, this strange tree was later researched and identified as genus (Michaelmoelleria F.Wen, YGWei & TVDo, gen. Nov.) And plant species (Michaelmoelleria vietnamensis F.Wen, ZBXin & TVDo, sp. nov.) new to world science ”Dr. Do Van Truong said Michaelmoelleria vietnamensis F.Wen, ZBXin & TVDo, sp. nov. The feeling of a winner TS. Do Van Truong added a memory, that is in 2018, during a trip to investigate and survey the flora of Vu Quang National Park (Ha Tinh), on the way back, colleagues discovered a tall vines. , beautiful flowers immediately take it and send it to you. At this time, TS. Do Van Truong is working in China, when he received the photo, he had a premonition that this was a very strange plant in his group. TS. Do Van Truong on a field trip When he returned home, he decided to find this vine. By the end of 2020, TS. Do Van cooperated with Vu Quang National Park to conduct a field trip to an area where strange plants were recorded before. This is a dangerous terrain and very far from the ranger station, so the group decided to sleep in the forest with determination to “hunt” with strange trees. At 6 am, the group will start their journey from the ranger station until 4pm to reach the desired area. However, within a radius of 1 km where colleagues used to take pictures, PhD. The red-eyed field still cannot see vines or regenerated seedlings of strange plants. TS. Truong commented that it is possible that individuals of strange plants have died due to the strong impact of previous droughts. At 5:30 it was dark, the group decided to camp, rest and drink wine for the sad: “Quiet space, darkness covered, and depressed mood. That feeling, I still remember until now ”, TS. Do Van Truong recalls. 7:30 the next morning, TS. Do Van Truong decided to search again, in the hope that the tree has flowers, that is to bear fruit, and is a source of seeds for regenerating seedlings. This is an area where the forest is not affected, definitely the trees are just around somewhere. He went back and forth many times, digging through the forest ropes, he finally found, it was a tree trunk lying hidden in a large cluster of trees. “At that time, she was sweaty and tired. But the feeling of victory is great ”. Up to now, on the basis of the results of analysis and research, PhD. The school has confirmed that this is a new plant species for world science, named: Aristolochia vuquangensis TVDo, sp.nov. Aristolochia vuquangensis TVDo, sp.nov. Fruit for efforts Hard, even dangerous, however, TS. Do Van Truong has received “sweet fruits”. In the period 2010-2020, PhD. Do Van Truong and colleagues have discovered and described 1 genus and 28 new species of higher plants for world science, of which 1 genus and 22 species were discovered and described in Vietnam. Also in the period from 2010-2020, PhD. Do Van Truong and colleagues have published a total of 26 scientific works describing new plant species in international journals. In which, 23 works were published in prestigious international magazines. According to TS. Do Van Truong, research to discover and describe new species for science, especially newly discovered species in Vietnam is of great significance. The first is to highlight the role and importance of biodiversity in Vietnam, which is a solid scientific basis for classification for conservation and application research. learning, probiotics …). In addition, scientists initially researched, propagated and successfully conserved a number of new species. This is an important basis to conduct research activities to develop precious plant genetic resources in Vietnam for the needs of use (medicinal herbs, ornamental plants, food for insects …), making an important contribution to the process. process of conservation and sustainable development of wild plant species. There are many concerns Being enthusiastic and pursuing plant research for many years, PhD. Do Van Truong said that he himself still has a lot of concerns. “Vietnam is a country with high biodiversity, but we do not have an in-depth research program on Vietnam’s flora. This is very unfortunate. We hope that there will be a unit with sufficient expertise and international relations to conduct a methodical and extensive research on the flora of Vietnam ”, PhD. Do Van Truong confided. One more concern of TS. Do Van Truong, that is attracting young people to participate in plant research. Part of the reason is that basic research is always a “silent” industry that has not been given adequate attention and investment. Moreover, the difficult life makes many young people who graduated from school are not eager to do research but turn to another direction. “If this situation continues, not knowing after 10-20 years, who will we marry to continue our work”.

Customers come to Mr. Loi garden to order flowers. Photo: Thanh Nghia.

Currently, the selling price of these flowers is dozens of times higher than that of ordinary flowers, helping his family have an attractive income source.

Anh Loi said that these flower varieties originated from Thailand, which he imported and began to experiment and propagate for about 2 years and this was the first year he launched to the market. The special feature of these varieties is that the plants flower all year round, with strange flower colors, looking very beautiful.

Currently, the orange and golden phoenix flowers have just been propagated for more than a month, only about 1 inch high, the selling price ranges from 150 to 180 thousand VND, only the plants are about 5 feet high and have given flowers the selling price. up to several million dong per tree.

In particular, in Mr. Loi, there are several plants that produce 2 kinds of flowers on the same rare tree, so the selling price is 3 times higher than that of conventional trees.

According to Mr. Loi, this cultivar flower blooms all year round, currently most of the seedlings in his garden have been ordered by traders, many customers have come to buy but supply is not enough.
