[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

[Method] Media suppIemented with different combinations and concentrations of hormones were pre-pared for anther cal us induction, proIiferation, differentiation and regeneration. [Re-sult] MS＋1.0 m/L 2, 4-D＋0.5 mg/L 6-BA was the optimum medium for anther cal us induction. MS＋1.0 mg/L KT＋0.1 mg/L NAA was the optimum medium for cal us proIiferation. MS＋2.0 mg/L 6-BA＋0.3 mg/L NAA was the optimum medium for in-duction of adventitious buds. MS＋0.3 mg/L IAA was the optimum medium for root-ing of adventitious buds. The highest rooting rate was onIy 37.5 because induction of rooting was a difficuIt work. [Conclusion] The resuIts wiI provide references for outcross fertiIity and genetic improvement of eggpIant.展开更多
