[Effects of lingfasu on embryoid and plantlet formation of Panax notoginseng in vitro].

On the medium MS added the right amount of 2,4-D and LFS (Angustmycin) and cultured under dark condition, the callus from stem segments of Panax notoginseng could induce a lot of embryoids. In 2-3 months, the ratio of embryoid formation reached about 90%. Then transplanted on MS + 2,4-D 1.

[Effects of angustmycin on callus occurrence and proliferation of Panax notogingseng in vitro].

In order to explore quick, efficient inducement and proliferation of Panax notogingseng callus, the stem sections were taken as explants in the following 5 groups of medium: 1. MS + 2,4-D 2 mg/L (CK), 2. MS + 2,4-D 2 mg/L + N6-BA 2 mg/L, 3.
