| 摘 要： | 以茎尖为外植体进行了离体快繁研究。利用6-BA×IBA和6-BA×NAA两种激素组合诱导丛生芽,6-BA×IBA激素组合的最佳增殖培养基是MS+6-BA0.5 mg/L+IBA0.1 mg/L,增殖系数可达6.5;6-BA×NAA激素组合的最佳增殖培养基是MS+6-BA0.5 mg/L+NAA0mg/L,增殖系数可达6.1;两种组合无显著性差异。在MS基本培养基上即可生根且长势良好,生根率为100%;诱导丛生芽试验中6-BA浓度不能超过0.5 mg/L,否则会有愈伤组织出现。

| Abstract: | In order to protect the wild resource of Scutellaria barbata D.Don,its rapid propagation in vitro was studied using shoot-tip as explant.The results showed that the optimal mediums for the bud differentiation were MS 6-BA 0.5 mg/L IBA 0.1 mg/L and MS 6-BA 0.5 mg/L NAA 0 mg/L.Multiplication coefficients of the two were 6.5 and 6.1,respectively but there was no significant difference between them.MS medium was the optimal medium for root formation and the rooting rate was 100 %.Concentrations of 6-BA should be lower than 0.5 mg/L in order to avoid callus formation during shoot induction. |
