ABSTRACT
Object To apply the technique of tissue culture to the rapid propagation of Stemona japo-nica (Bl.) Miq. and lay a foundation for the rapid propagation of its improved breeds. Methods The explants used for culture were stem segments with axillary bud of S. japonica. The media were MS basal media containing different plant hormones. Results The results of the study indicated that shoots could be induced successfully in MS medium supplement with 6-BA 3.0 mg/L and IBA 0.2 mg/L, and the better medium for bud multiplication and root inducement were MS+6-BA 3.0 mg/L+IBA 0.3 mg/L and MS+IBA 2.0 mg/L+AgNO 3 0.5 mg/L respectively. After 30 days' culture, the rate of rooting reached over 50%. The survival rate of transplanting was raised obviously by using 20 mg/L carbendazim treatment. Conclusion The primary plant regeneration system of S. japonica has been established, which makes the industrial production possible.
