摘　　要：为了建立高效的辣椒离体再生体系,选择5种不同基因型的辣椒无菌苗,研究了添加不同激素配比的MS培养基对芽诱导分化、芽伸长增殖、生根和移栽等的影响。结果表明:MS+6.0 mol·L^(-1)6-BA+1.0 mol·L^(-1)IAA+5.0 mol·L^(-1)Ag NO_(3)组合为芽分化的最适培养基,可诱导出白色松软的愈伤组织,Flamingo-bill诱导率为100.0%,子叶诱导率为86.7%。MS+3.0mol·L^(-1)6-BA+2.0 mol·L^(-1)IAA+5.0 mol·L^(-1)Ag NO3+1.5 mol·L^(-1)GA3组合为不定芽伸长的最适培养基,Flamingo-bill不定芽伸长率为66.7%,子叶不定芽伸长率为30.0%。MS+0.5 mol·L^(-1)NAA组合为不定芽生根的最适培养基,Flamingo-bill和子叶不定芽生根率均为100.0%。通过Flamingo-bill和子叶外植体均能获得再生植株。In order to establish an efficient in vitro regeneration system for chili peppers,five different genotypes of aseptic chili peppers were selected,and the effects of the addition of MS medium with different hormone ratios on bud induction and differentiation,elongation and proliferation,root growth and transplantation were investigated.The results showed that the combination of MS+6.0 mol·L^(-1)6-BA+1.0 mol·L^(-1) IAA+5.0 mol·L^(-1) AgNO_(3) was the optimal medium for bud differentiation,which could induce white fluffy healing tissues,with a 100.0% induction rate of Flamingo-bill and 86.7% of cotyledons.MS+3.0 mol·L^(-1)6-BA+2.0 mol·L^(-1) IAA+5.0 mol·L^(-1) AgNO3+1.5 mol·L^(-1) GA3 was the optimal medium for adventitious bud elongation,with 66.7%ratios of adventitious bud elongation in Flamingo-bill and 30.0%ratios in cotyledons adventitious bud elongation.MS+0.5 mol·L^(-1) NAA was the optimal medium for adventitious bud rooting,the rooting rate of both Flamingo-bill and cotyledon adventitious bud was 100.0%.Regenerated plants were obtained from both Flamingo-bill and cotyledon explants.
