比较了不同种类、不同浓度和不同配比的外源激素对丹参茎尖培养的作用 ,建立了丹参快速繁殖的方法 .结果表明 :在 MS培养基中 ,1.0 mg/ L BA和 0 .1m g/ L NAA配合使用时茎尖的生长状况最好 ,茎尖的成活率高达91.4 % ;GA对茎尖分化有抑制作用 ;附加 1.0 m g/ L BA时芽的增殖效果最好 ;附加 0 .5 mg/ L IAA有很好的诱导生根的作用 ,而且可以缩短生根周期
The effects of exogenous hormones of different kinds, concentrations and ratios on the culture of Salvia miltiorrhiza were compared, and the rapid propagation of Salvia miltiorrhiza was established. The results showed that 1.0 mg / L BA and 0.1 mol / L NAA, the shoot tip grew best, the shoot tip survival rate was as high as 91.4%, GA inhibited shoot tip differentiation, buds had the best proliferation effect when 1.0 mg / L BA was added, mg / L IAA has a good effect of inducing rooting, and can shorten the rooting cycle
