Abstract:

In this study, the effects of different concentration trace elements in NT medium on adventitious root growth, the accumulation of total alkaloid and triptolide of Tripterygium wilfordii were investigated. The results showed that the trace elements of Mn,Zn,Cu,Co,B,I and Mo influenced the adventitious root growth and the accumulation of total alkaloid and triptolide. The optimal NT medium trace elements for the growth of adventitious root were 2 times the concentration of MnSO4,with concentrations of ZnSO4,CuSO4,CoCl2,H3BO3 and KI maintained unchanged and 2 times concentrations of Na2MoO4.As for the accumulation of total alkaloids, the concentration of KI had no impact on the accumulation of total alkaloids, 2 times the concentration of CoCI2 and CuSO4, removal of H3BO3 and Na2MoO4, and 4 times concentrations of MnSO4 and ZnSO4 were suitable. In NT medium, 2 times the concentration of ZnSO4 and CuSO4, removal of H3BO3, Na2MoO4 and CoCl2, and 4 times concentrations of MnSO4 and KI were optimal for the accumulation of triptolide.

Key words: Tripterygium wilfordii, adventitious root, tissue culture, trace elements, secondary metabolites
