Study on Tissue Culture Techniques for Radicle of Bletilla Striata / 中国药师

ABSTRACT

Objective:To seek the best part and optimal culture medium for the tissue culture of Bletilla striata. Methods: The effects of hormone concentration and proportion on the induced differentiation, propagation and rootage of Bletilla striata were investiga-ted. Results:The radicle of Bletilla striata was the best part to induce the clustered shoots with the optimal culture medium of 1/2MS+1. 0 mg·L-1 6-BA+2. 0 mg·L-1 NAA. The best hormone concentration for inducing the clustered shoots was MS+1. 0 mg·-1 L 6-BA+0. 05 mg·L-1 NAA, and the optimal rooting medium was 1/2MS+0. 5 mg·L-1 NAA. Conclusion: The tissue culture system for Bletilla striata is established.
