Seed propagation of Mycetia balansae Drake is not easy, due to low germination rate and low viability, so it is very rare in nature. In order to conserve this plant as well as to use for commercial purposes in cooperation with Tue Linh Co.Ltd, providing a large number of plants is necessary and in vitro tissue culture technology could be solve this problem. Therefore, the study on "Callus induction and plant regeneration in vitro from leaf explants of mycetia balansae drake" was carried out.
