摘　　要：以三七景天嫩叶为外植体,进行了离体快繁技术研究。结果表明:愈伤组织诱导最佳培养基是:MS+6-BA 2.0mg/L+NAA 0.5mg/L;芽诱导最佳培养基是:MS+6-BA 1.5mg/L+NAA 0.2mg/L;芽增殖最佳培养基是:MS+6-BA 1.0mg/L+NAA 0.2mg/L。组培苗生根的最佳培养基是:MS+NAA 0.3mg/L+活性炭1.6g/L。Taking the new leaves of Sedum aizoon as explants, the rapid propagation in vitro of which was studied. The results showed that the optimal medium for callus induction was MS＋6-BA 2.0 mg/Lq-NAA 0. 5 mg/L;the optimal medium for shoot induction was MS＋6-BA 1.5 mg/L-FNAA 0. 2 mg/L;the optimal medium for shoot proliferation was MS＋6-BA 1.0 mN/L＋NAA 0. 2 mg/L;the optimal medium for rooting was MS＋NAA 0. 3 mg/L＋AC 1.6 g/L.
