摘要
以紫色茎秆海芋的顶芽和侧芽作外植体开展了相关的组织培养试验,探索了不同培养基组合对紫色茎秆海芋的诱导培养、丛芽增殖、幼苗生根的影响。试验结果表明:MS+BA6.0 mg/L+NAA0.1 mg/L培养基对紫色茎秆海芋顶芽、侧芽组培的诱导效果较好;MS+BA5.0 mg/L+NAA0.1 mg/L培养基对其丛芽增殖效果最佳,增殖系数达4倍多;而1/2MS+NAA0.5 mg/L培养基有利于其壮苗、生根,且植株长势健壮。
Taking the terminal buds and lateral buds of Alocasia macrorrhiza as experimental materials, experiments were conducted to study the effect of different media on bud induction, fascicular bud propagation and rooting of plantlet. The results of experiments showed that the optimum media for bud induction, fascicular bud propagation and rooting of plantlet were MS ＋ BA6. 0mg/L ＋ NAA0. lmg/L, MS ＋ BA5.0 mg/L ＋ NAA0. 1 mg/L and 1/2MS ＋ NAA0. 5 mg,/L respectively.
