[Objective] This study aimed to establish a tissue culture and rapid propagation system for Lycium ruthenicum Murr.[Method] Using tender stems of L.ruthenicum as explants,MS as basic culture medium,the effects of different factors on primary culture,subculture and rooting of L.ruthenicum plantlets were investigated.[Result] The most appropriate medium for primary culture of L.ruthenicum was MS ＋ ZT 0.2 mg/L ＋ IBA 0.01 mg/L,in which axillary buds grew well and were rarely vitrified with the germination rate of 88.73%.In addition,ZT exerted significantly better effects on subculture and proliferation of L.ruthenicum plantlets than 6-BA.The most appropriate medium for subculture and proliferation of L.ruthenicum plantlets was MS ＋ ZT 0.15 mg/L ＋ IBA 0.01 mg/L,in which L.ruthenicum plantlets grew rapidly and robustly without vitrification,and the proliferation multiple reached 5.83 times.The most appropriate medium for rooting of L.ruthenicum plantlets was MS ＋ IBA 1.0 mg/L,in which the rooting rate reached 100%.The most appropriate substrate for transplanting and hardening of L.ruthenicum plantlets was humus soil：perlite = 1：1,in which L.ruthenicum plantlets grew well with the survival rate of 92.37%.[Conclusion] This study provided theoretical basis for largescale production and popularization of L.ruthenicum.
