[Methods] With cotyledon of S. torvum as the research object, ef- fects of hormone combination on callus induction and adventitious buds differentia- tion of S. torvum were researched. [Results] With cotyledon of S. torvum as the ex- plants, the optimal culture medium for callus induction and adventitious buds differ- entiation was MS＋2.0 mg/L 6-BA＋0.3 mg/L NAA. The induction rates of callus and adventitious bud reached 100% and 85%, respectively. The number of average buds was 6. The optimal culture medium for the induction of adventitious roots was MS＋ 0.3 mg/L IAA. The rooting rate reached 100% and the number of average roots was 9. [Conclusions] One-step induction of callus and adventitious buds simplified the mass propagation system, and enhanced the test test efficiency.s展开更多
