Flowers bloom in test tubes

Hearing interesting information about flowers blooming in closed containers, we went to the biotechnology laboratory of Ho Chi Minh City University of Natural Sciences in Linh Trung ward, Thu Duc district, which made this interesting.

Master the inoculation procedure in vitro

In different, small and sealed pots, the tree still sprouted and blossoms, blooming like smiling and welcoming guests. The owner of the planting technology and making the flowers bloom in this test tube is a group of 9 4th year students, a student of Ho Chi Minh City University of Natural Sciences led by Do Hoang Thien Y and Tran Thi Trinh, under the direction lead by Dr. Bui Van Le.

At the end of 2005, this group of students began experimenting with growing plants in test tubes sealed with the external environment. This is not a simple job because it is contrary to the law of nature: the tree must have air to breathe, nutrients to grow. ' It is a challenge for many scientists not only in Vietnam,' said Dr. Bui Van Le.

'The most difficult thing for us is to find the procedure for inoculation without being infected,' said SV Tran Thi Trinh. That is tissue culture into the test tube. From a small leaf, by tissue culture method, after 2 to 3 months, the leaves grow into sprouts, then about two or three weeks later the tree branches, flowers. The second difficulty is to grow normal growth tissue in a sealed test tube, which means that it is necessary to find appropriate environmental and physiological conditions like that for the growing tree. The test tube environment is a completely sterile, windless environment without rain, so the only source of life of the plant is the nutritional environment provided by farmers.

Just let us see the nutrients for solid, transparent, green, red, purple, yellow plants depending on the color, SV Tran Thi Trinh said ' technology secret ' lies in this nutrient. For plants to grow well, flowering, not putting plants under the sun. The plant is only suitable for light or dark light.

Catch the tree to flower at will

Currently, this group of students has planted thousands of trees with many different types of flowers in a variety of sealed sizes of different sizes, with the probability of transplanting live plants to 90%. In particular, scallops often have a life expectancy of about 6 months to change the nutrient environment, but in vitro cultivation has lived for 1 year and developed normally.

According to the research team, it is very difficult to have flowering plants in vitro. There must be an ideal diet and environment such as in addition to the natural flowering of new plants. The students have done this miracle. But even more miraculously, this group forced the tree to flower at will. At the lab, there are now 100 plants that catch flies and dozens of interlaced blooms. But more happy, as Do Hoang Thien Y said, 'A sycamore tree can flower well . is the most fun. Because it is not according to the physiological mechanism of plants, but by forced micropropagation technology to produce flowering plants'. Beautiful, small interlining elements with purple, very natural and fresh color for a week, longer than intercooling flowers in natural conditions for up to 3 days.

The home of the object

The most convenient thing for growers is not to water and care, but the tree is still growing normally. In vitro plants come in many sizes, with a small size of only 5-6 cm but of up to 20 cm or larger. Plants and flowers growing in vitro are just as normal as in the natural environment.

With these advantages, in some countries such as Korea, Japan, in vitro flowers are very popular. They quickly became eye-catching indoor objects. Estimated selling price of a tree in a test tube is about VND 25,000. You can buy it at the Biotechnology Center, HCMC University of Natural Sciences.

5,000 flower plants for the Spring Flower Festival

The Biotechnology Laboratory of Ho Chi Minh City University of Natural Sciences is expected to produce 5,000 plants and flowers in vitro to join Ho Chi Minh City Spring Festival from 25 December to 8 Lunar New Year Tao Dan.These 5,000 trees include many types such as: dendro orchids, scallops, petunia, stevia, poinsettia, lilacs, sam sung cigarettes . They are considered unique products in this Spring Spring Festival.
