The Institute of Agricultural Science and Technology in the South Central Coast Applied technology tissue culture technology to preserve the rare orchid gene source of Dai Thousand An Lao.Theo Master Le Duc Dung, Deputy Head of Vegetable, Flower And ornamental plants under the Institute of Agricultural and Agricultural Science and Technology Institute (abbreviated as Institute of Science and Technology DHNTB), Lan Chau is the endemic species of Natural Forest An Lao District (Binh Dinh) and mainly distributed in the The area has a height of over 600m above the sea surface. A single orchid group, with beautiful shape, vertical body, big roots, blue leaves, twisted leaves without leaf stripes like Dai Chau varieties of Thailand, Laos ..
. Lan Chau Lan grows horizontally, curved down symmetry, stems are classified into 2 rows of reorganization, leaves on a row alternating with the leaves of the other, leaves length from 30-40cm, 4-5cm leaf width. Flowering 20-40cm long, drooping flowers, white cotton with purple spots, purple lips.Hoa blooming at the end of December lunar calendar, floral durability from 25-30 days should be very popular
In particular, it is a very fragrant flower incense, which is the great advantage of Chau orchids distributed in An Lao forest. Chau Lan Lan Park is applied by the Institute of Agricultural Engineering Science and Technology. . Photo: Vu Dinh Thung.Lan Chau for beautiful flowers, which is a spread of the quarterly has been confirmed with economic value. Over the years, before the demand for Lan Forest dates, the value of AN Lao's orchids increased high. Currently, an orchid orchid for fortune telling flowers costs about VND 2 million, causing many people to despite the danger and crept into the deep-exploiting forest to destroy the natural resources of natural resources increasingly exhausted, There is a high risk of getting genetic resources. Besides, Chau Lan seeds are the same as other types of orchids that have no endopiums, so they do not germinate themselves in normal conditions, but the new symbiosis is affordable Functional germination. The exploitation process also causes the amount of spread seeds spread in natural days a little. In addition, climate change along with human impact has narrowed the natural forest area, losing the appropriate living environment of AN LAO
Therefore, in natural conditions, it is difficult to germinate and develops into a seedlings, increasing the risk of this extinction of this quarter. Studying in the South Central Coast agricultural techniques are checking buds of Chau Lan. Photo: Vu Dinh Thung. Before the above situation, the research team of the DHNTB Institute of Science and Technology has collected the fruits of the Chau Lan from An Lao forest at the nine physiological stage, then applied tissue culture method (breeding In vitro) for preserving and developing LAN LAN LANGE TIME. According to Master Le Duc Dung, Invitro culture nutrition environment can be applied to many different plant objects. In the formula to meet the nutritional content such as multivariate elements, trace, vitamins, regulators of growth, depending on plant objects, different use rates. Each laboratory has its own technological know-how Applicable to each different plant object such as chrysanthemum, orchids, forestry seedlings. In addition to nutritional factors, light factors, the temperature is also important in the process of culture. Chief of the Department and Deputy Head of the Department of Plants and Vegetables Bonsai of the Institute of Industrial Science and Technology in the South Central Coast are checking The development of the growth of the Chau spread pots is grown in the membrane house.

Time since seeding into a nutritious environment until the germination of seeds takes about 2 months. Then continue to choose Healthy development embryos transplanted into a seedling environment, after 2 months the tree continues to be transplanted Well to create a complete tree. When plants range from 4-5 roots, 2 leaves are finished, they can train their familiar trees with temperature and light conditions in nursery conditions, enhance the survival rate of seedlings when planted. " We apply Invitro culture technology to be able to preserve, exploit and use Gene resources Lan Lan Chau An Lao has been 5 years now to meet the needs of people and provide a number of markets Large number of seedlings, contributing to conservation of genetic resources distributed in An Lao forest ", Master Le Duc Dung, said. Currently, because Lan Chau in nature is now exhausted, Lan wants to own a natural orchid taking 2 million dong. Meanwhile, Lan Chau An Lao is planted by the Institute of Science and Technology DHNTB selling only VND 300,000 / tree. Play players in Binh Dinh province, Binh Dinh people are settled in Ho Chi Minh City and many other provinces and cities know the value Of An Lan's Lan Belt, this type of orchid is very strong. "Old plants decide on the price of orchids, orchids for long-five spreads and brilliant flowers and flowers are brilliant," Master Dung shared. South Central Is owning.
