  • Title: [Study on tissue culture of Bolbostemma paniculatum].
    Author: Li CQ, Wang ZZ.
    Journal: Zhongguo Zhong Yao Za Zhi; 2006 Mar; 31(5):369-72. PubMed ID: 16711416.
    Abstract:
    OBJECTIVE: To study the method of callus induction and culturing of Bolbostemma paniculatum and its relationship with accumulation of tubeimoside. METHOD: Stem and leaf were selected as explants. The effects of growth substances and their combinations at different concentrations on callus formation and propagation on MS and B5 basic medium were studied. RESULT: The optimal compositions of medium that induced calli from stems and leaves were the MS medium supplemented with 2,4-D 2.0 mg x L(-1), NAA 0.5 mg x L(-1) and BA 1.0 mg x L(-1) and the MS medium supplemented with 2,4-D 0.5 mg x L(-1) and NAA 2.0 mg x L(-1), respectively. The calli cultured on the MS medium supplemented with 2,4-D 2.0 mg x L(-1), NAA 0.5 mg x L(-1) and BA 1.0 mg x L(-1) were optimal for the accumulation of tubeimoside. A uniform and stable callus line could be formed from the calli cultured repeatedly on B5 medium supplemented with 2,4-D 2.0 mg x L(-1), NAA 0.5 mg x L(-1) and BA 1.0 mg x L(-1). CONCLUSION: Using stem and leaf as explants, the method of the callus induction and culture of B. paniculatum was established and it could provide some references for the production of tubeimoside by tissue and cell culture.
