The phoenix flower tree has the English name Flamboyant, also known as phoenix, oval west, scallop… The phoenix is ​​a red-flowered plant found in tropical or subtropical regions. Phoenix flowers bloom from about late April to June, depending on the region. This flower is native to Madagascar. In addition to its ornamental value, phoenix also acts as a shade tree in tropical conditions. The phoenix tree is quite tall, about 5m to 12m. The phoenix tree has wide spreading foliage and its dense foliage provides shade. The phoenix flower has 5 petals spreading bright red or orange-red, often forming large clusters. In Vietnam, the phoenix tree was introduced and planted by the French in the late 19th century in big cities such as Hai Phong, Hanoi, Da Nang, and Saigon. Even Hai Phong is also known as the “City of red phoenix flowers”. In Hanoi, the phoenix tree is grown quite popularly. They are planted on sidewalks, parks, schools. When the phoenix flowers begin to bloom, it is also the time to signal exam season, summer, and school release season. That’s why, the first sentence of the song Phuong Hong: Carts full of phoenix flowers, where is my summer baby going… has been deeply imprinted in the hearts of many young people. The phoenix flower rose strongly in the terrible heat of Hanoi. Along the rivers, lakes and both sides of the capital’s roads are now tinged with brilliant red. The phoenix trees on the street produce bright red flowers, combined with the purple color of the mausoleum, the yellow color of the scalloped flowers, creating the summer colors of Hanoi. All of them light up in many generations of Hanoians the fire of love every time they look at those bright colors.

Khan’s farm is located in Malihabad, a mango paradise in northern India with more than 10,000 hectares. Amir Khusro, the Indian-Persian poet, has called mango, native to India and tropical, subtropical climate, as “the most beautiful fruit of Hindus”. The cultivation of mangoes in India began many centuries ago during the Mughal Empire. This country is also the largest mango producer in the world, with more than 1,000 varieties and accounting for more than 40% of production. Mr. Khan and the mango season were good last year. The story of “mango trees 300 kinds of fruits” With the help of his son, Khan has grown mangos on 22 acres of farmland, a property cultivated by his grandfather since the 1900s. When Khan dropped out of high school and started his life, his family planted only a few local varieties, similar to nearby mango farms. Khan’s dream of grafting mangoes rekindled at the age of 15, when he saw a rose-hybrid tree in a friend’s garden. The flower tree had flowers of different colors that made him wonder if a single tree could produce such fruits. “Naturally I want to propagate the mango tree like what I saw on that rose bush,” he said. The 300-fruit mango tree is inspired by a hybrid rose bush. At the age of 17, Mr. Khan successfully grafted 7 varieties of mango into one tree. After the flood killed the tree, he determined to learn more about grafting in the family orchard. Over the years, Khan has been steadily improving his art of grafting. In 1987, he started grafting different varieties onto a 100-year-old mango tree. These mango varieties were collected by him from all over the country, including rare varieties. Mr. Khan said that the tree currently has more than 300 types of mangoes and he calls it Al Muquaraar. “Miracle Mango Tree” has a wide canopy, large enough to accommodate 15 people sitting under it. The branches are heavy with fruit with leaves of different colors such as gray green or olive green … The mango fruit on each branch also has its own shape: round or oval, some green, yellow, others have orange, pink and purple. The variety of each type is identified by a small label on the stalk: Dasheri mango from a nearby village, Himsagar from West Bengal, Langra from Bihar or prized Alphonso mango, sweet, saffron-colored mango in demand. high domestically and internationally. Mr. Khan’s three famous mango varieties are Tommy Atkins, Suvarnarekha, and Husn-e-Ara. “This miraculous mango tree is not just a tree, but an orchard, a universe,” said Khan. Free fruit donation, breed new breeds When asked how to protect trees from birds and insects, Mr. Khan said: “I don’t drive them away. The well-being of nature is for all to share.” During the harvest season, Khan and his son pack farm produce for sale and export. They give free fruit of “miracle tree” to visitors to the garden. “Like two kids from the same parents but different in looks and personality, mangoes sprouting from the same seed can also be completely different,” Khan said of each mango, as if it were kids. In addition to grafting, Mr. Khan also bred new varieties of mango, experimented with flavor and texture and gave them creative names. He named his new mango variety after Prime Minister Narendra Modi (Namo Aam) and Bollywood actor Aishwarya Rai. Khan said: “I created a mango after the famous cricketer Sachin Tendulkar. He called to thank him and expressed his happiness.” Most recently, he named two new mangoes “doctor aam” and “police aam” to thank the work of the rescue pioneers during the pandemic. Many famous people visited Mr. Khan’s farm. Mr. Khan won many awards, including the Padma Shri, one of India’s highest civilian awards, and recorded in the Limca record book. He visited Dubai and Iran to teach the art of grafting. In 1999, he created a mango tree with more than 54 varieties for the Mughal garden inside Rastrapathi Bhavan, the official residence of the President of India. “Mango grafting is just an art and has no commercial value,” said DK Sharma, vice president of the Mango Growers Association of India. Mr. Khan disagrees, saying that grafting is very common in commercial fruit and nut production. He considers it an art of practical value.

Towards the end of this century, organisms living on the ocean floor faced increasing dangers from ocean warming. (Photo: thiennhien.net) According to climate warming projections, the number of species has decreased in the equator and increased in the subtropics since the 1950s. This is the general state of all 48,661 species and they are divided into sub-species. seabed (benthic) and in open water (floating fish area), fish, molluscs and crustaceans. Results from a study led by the University of Auckland (New Zealand) show that open water marine species in the Northern Hemisphere tend to move more towards the North Pole than benthic species. Meanwhile, species in the southern hemisphere do not have a similar wave of movement. The reason is that the warming ocean in the Northern Hemisphere is more pronounced than the Southern Hemisphere. In the past, the tropics were always considered to be stable and have an ideal temperature for reproduction because so many species of organisms appear there. Now the defined tropics are not so stable and are becoming too hot for many species. This study is the result of doctoral work by lead author Chhaya Chaudhary at the University of Auckland and builds on a series of studies in a joint research group that delineates documents and data on taxonomy groups. Specifically, these include crustaceans, fish and worms. The data is taken from the Ocean Biodiversity Information System (OBIS), a free accessible online world database established by Professor Mark Costello of the University as part of the marine biology investigation, a global marine exploration program from 2000 to 2010. Recorded information about the time and location of species was compiled into latitude ranges and a statistical model was used. Use to calculate variables in sampling. Last year, Professor Costello co-authored a study that found that although marine biodiversity escalated and peaked at the equator during the last ice age 20,000 years ago, it was pulled flat before the status quo. global warming in the industrial era. This study uses fossil records of marine plankton buried in deep-sea sediments to track changes in species diversity over thousands of years. The latest research on a decade scale shows that this flat drag has continued over the past century, and that the number of species is now decreasing at the equator. This research, and other work underway, shows that the number of marine species declines when the average annual seawater temperature is above 20 to 25 degrees Celsius (varies with different species. ). As one of the lead authors of the current International Commission on Climate Change (IPCC) 6th Assessment Report, Professor Costello argues that these findings are of great significance. “Our work shows that man-made climate change affects marine biodiversity on a global scale across all species. Climate change is already here for us and is happening at an ever-increasing rate. We can predict general trends in species diversity, but due to the complexity of ecological interactions, it is currently unclear how rich marine life and fisheries will be. how to change according to climate change ”, said Professor Costello. According to a new study published in the journal Nature Climate Change, the rate of climate change in the depths of the world’s oceans could be seven times higher than current levels in the second half of this century even if greenhouse gas emissions have been significantly reduced. Different global warming at different depths has a major impact on the wildlife of the oceans, causing disconnections as species that rely on each other for survival are forced to move. Professor Anthony Richardson of the University of Queensland and CSIRO, who is also one of the 10 authors of the study, pointed out: “What really worries us is that when we move down deep in the ocean, the climate velocity moves downwards. transfer at different speeds ”. This can create a disconnection with species that depend on organic organisms of different layers. Tuna, for example, live in the middle layer with a depth of 200 – 1000 m, but they need plankton near the sea surface. Professor Richardson emphasized that the results of the study are of concern, with climatic speeds varying depending on the depth of the ocean and the tendency for species to move to be uneven. This may mean marine protected areas established to protect species or habitats may no longer work as species move out of protected areas into unprotected areas.
