[Method] With tender stem of Hemistepta lyrata Bunge as material, the conditions needed in calluses induction and differentiation, adventitious bud differentiation and radication, test tube seedling cutting and transplantation were studied. [ Result] The results showed that the optimum medium for granulated calluses induction from tender stem was MS + BA 0.3 mg/L +2,4-D 1 -1.5 mg/L, for granulated calluses and adventitious bud differentiation was MS + AgNO31.5 mg/L + BA 0.4 mg/L + NAA 0.1 mg/L. 1/2 MS + IAA 0.6 mg/L was suitable for test tube seedling rooting and regeneration, and cinder was used as transplantation and cutting substrate. [ Conclusion]This study will provide the scientific reference for choosing the feasible medium in tissue culture of Hemistepta lyrata Bunge.展开更多
