Screening of Differentiation Medium for Apocynum venetum L. Seeds

[Objective] To screen out an optimal medium for induction and differentiation of Apocynum venetum L. seeds. [Method] To obtain the optimal medium, effects of NAA concentration on the differentiation of A. venetum seeds were investigated using MS as the basic medium and pollution-free bulbils as explants. [Result] Different concentration of NAA flavored the survival of A. venetum seeds, among which there was no significant difference. The optimal medium for differentiation of A. venetum seeds was MS+0.02 mg/L NAA+1.00 mg/L IBA +10 g/L agar+30 g/L sucrose. [Conclusion] This study could provide basis for the industrialized production of A. venetum.
