[Objective] The aim of this study is to establish the rapid micro-propagation system in Thesium chinense Turcz.[Method]With stem fragments of wild Thesium chinense Turcz as explants,different culture media were designed to conduct induction culture,strengthening plantlet culture and in vitro rooting.[Result]The optimum medium for inducing clustered shoots was determined to be MS medium appended with 1.5 mg/L 6-BA,0.01 mg/L NAA and 0.3 mg/L 2,4-D;in addition,60 mg/kg ABT was suitable for rooting,by which the percentage of rooted plantlets reached 76.6%.[Conclusion]This study simplified the procedures of tissue culture in Thesium chinense Turcz and enhanced the proliferation rate,providing basis for artificial cultivation and resource protection of Thesium chinense Turcz.
