ABSTRACT
Objective To purify and rejuvenate the plant of Curcama kwangsiensis,improve the transplantation survival rate of cultivars,and make the convenience of storagement and management for the cultivars production.Methods The rhizome plantlet formation of C.kwangsiensis was induced by regulating both of macro-element and sucrose concentration in the MS culture medium.Results Both of them were very important influence factors on the rhizome plantlet formation of C.kwangsiensis.Media 1/2 MS and 6% sucrose were adaptable to the rhizome plantlet formation of C.kwangsiensis,had the best effects on the formation rate of the rhizome plantlet,diameter and direct transplanting rate of the rhizome plantlet.Both plantlet and root system development were stronger.Conclusion In the present research,it is successful in inducing the rhizome plantlet formation of C.kwangsiensis.
