【摘要】 以桔梗(PlatycodongrandiflorumJacq.DC.)的幼嫩茎尖、茎段为外植体,建立了桔梗的快速繁殖实验体系。最佳培养基组合为:诱导分化培养基MS+6蛳BA1.0mg/L+NAA0.05mg/L;增殖培养基MS+6蛳BA0.4mg/L+NAA0.1mg/L;生根培养基1/2MS+NAA0.5mg/L。更多还原

【Abstract】 The shoot apices and stem of Platycodon grandiflorum were used as explants, and the experiment system of rapid propagation was established. The optimum medium combinations were: callus induction and differentiation medium was MS medium containing 6-BA 1.0 mg/L and NAA 0.05 mg/L ; bud propagation medium was MS medium containing 6-BA 0.4 mg/L and NAA 0.1 mg/L; rooting medium which was 1/2 MS medium containing NAA 0.5 mg/L.更多还原
