| The shoot tip of Zhangxi taro was taken as material to study the effects of different exogenous
hormones on induction culture, proliferation culture and rooting culture of taro tissue cultivation, and to set up a
technique system for tissue culture and rapid propagation of Zhangxi taro. The results showed that disinfecting for 5-
6 minutes by using 0.1% HgCl2 was the best disinfection method for explant, MS+6-BA 2.0 mg/L+NAA 0.2 mg/L was
the suitable culture medium for cluster buds differentiation of Zhangxi taro, MS+6-BA 2.0 mg/L+NAA 0.2 mg/L was
the suitable proliferation culture medium and the proliferation rate reached 5.3, 1/2MS+IBA 0.20 mg/L+NAA 0.20
mg/L was the best culture medium for taking root, the best transplanting substrate was the combination of peat,
vermiculite, pearlite with 4：1：1. |
