[Objectives]To study the culture of callus produced by the leaves of the ethnic medicine‘E Se’,the induction of adventitious buds and the regeneration system of tissue culture seedlings.[Methods]Multi-factor orthogonal experiment was used to design and analyze.[Results]The best medium for callus induction was MS+2.0 mg/L 6-BA+0.1 mg/L 2,4-D.By comparing the effects of cytokinin 6-BA,KT and TDZ on induction of adventitious bud differentiation,it was found that the optimum medium for adventitious bud regeneration was MS+0.5 mg/L 6-BA+0.5 mg/L KT+0.15 mg/L IBA.Finally,adding 0.2 mg/L IBA(0.1 or 0.2 mg/L)to MS medium could effectively make regenerated seedlings produce roots,and the efficiency was more than 70%.[Conclusions]It laid a foundation for the large-scale cultivation of the seedlings of the ethnic medicine‘E Se’and the promotion of their artificial cultivation.

[Methods] Multi-factor orthogonal experiment was used to design and analyze. [Results] The best medium for callus induction was MS+2.0 mg/L 6-BA+0.1 mg/L 2, 4-D. By comparing the effects of cytokinin 6-BA, KT and TDZ on induction of adventitious bud differentiation, it was found that the optimum medium for adventitious bud regeneration was MS+0.5 mg/L 6-BA+0.5 mg/L KT+0.15 mg/L IBA.
