    摘要:

    以草莓品种红颜和丰香为试材,选择草莓匍匐茎的茎尖为外植体,以MS为基本培养基,研究了不同激素配比对草莓组培苗生长的影响。结果表明:(1)红颜最佳芽诱导培养基为MS+6-BA 1.5 mg/L+KT 1.5 mg/L;丰香最佳芽诱导培养基为MS+6-BA 1.5 mg/L+KT 0.5 mg/L。(2)适合红颜继代增殖培养基为MS+6-BA 1.0 mg/L+NAA 0.4 mg/L,增殖系数可达12.3;适合丰香继代增殖培养基为MS+6-BA 1.0 mg/L+IBA 0.1 mg/L,增殖系数可达18.8。(3)适宜红颜生根培养基为1/2MS+IAA 0.5 mg/L;适宜丰香的生根培养基为1/2MS+IAA 1.5 mg/L。

    Abstract:

    This study investigates the impact of various hormone proportions on the growth of strawberry somaclones,specifically using the Hongyan and Fengxiang strawberry cultivars as test subjects. The analysis entailed using the tips of their stolons as explants and employing MS as the principal culture medium. The results showed that, the best bud induction medium for Hongyan was MS+6-BA 1.5 mg/L+KT 1.5 mg/L, the best bud induction medium for Fengxiang was MS+BA 1.5 mg/L+KT 0.5 mg/L. The subculture proliferation medium suitable for Hongyan is MS+6-BA 1.0 mg/L+NAA 0.4 mg/L, the multiplication factor can reach 12.3. The proliferation medium suitable for Fengxiang is MS+6-BA 1.0 mg/L+IBA 0.1 mg/L and the multiplication factor can reach 18.8. The suitable rooting medium for Hongyan is 1/2MS+IAA 0.5 mg/L, the suitable rooting medium for Fengxiang is 1/2MS+IAA 1.5 mg/L.
