Mutant flowers gene after radiation projection

Experts from the Biology Research Department of Da Lat Nuclear Research Institute have succeeded in blooming flowers inside the test tube for some commercial flowers.

These varieties are irradiated with gamma rays at a certain dose before. The expert group has applied the combination of nuclear technology and tissue culture to help shorten the time to create mutant flowers on the shape and color of flowers in the laboratory.

Master Le Van Thuc, the leader of the research team, said the group has successfully conducted research on forget me not flowers, daisy daisy, Japanese daisies, torenia (another name is cat eye, joint) with the ratio Bulk flowering is 89.18%. According to Thuc, purebred varieties will be removed tissue culture in vitro until it develops into seedlings. While the seedling is growing in vitro, gamma irradiation stimulates the gene mutation to create a random change in color, shape, and flower shape. After irradiation, flower plants continue to be nourished in the test tube until the flowers bloom simultaneously.

All research and monitoring stages of flowering plants are carried out in sterile rooms so it is easy to select new varieties. In the past, to select mutant varieties with biological advantages to irradiate the original varieties and test them in the environment, this method has low efficiency due to the impact of the natural environment.
