摘要
[目的]优化橡胶草再生和遗传转化体系.[方法]以橡胶草茎和叶为外植体,以1/2MS和MS为基本培养基,研究不同激素浓度配比、外植体类型和激素浓度对橡胶草不定芽诱导和生根的影响.[结果]橡胶草进行组织培养的最佳外植体类型为茎,诱导不定芽形成的最佳激素浓度配比为1.O mg/L 6-BA和0.10 mg/L NAA.诱导不定芽生根的最佳激素浓度为0.10 mg/L NAA,生根率达100%,移栽成活率达95%以上.[结论]建立了橡胶草高效再生体系,对提高橡胶草组织培养的效率和转化率具有重要意义.
Abstract
[Objective] The aim was to optimize Tarquin kok-saghyz Rodin regeneration and genetic transformation system.[Method] With stems and leaves of T.kok-saghyz as explants,1/2MS and MS as the basic medium,effects of different hormone concentrations and explant types on adventitious bud induction and rooting were studied.[Result] The results showed that the best explant for tissue culture was stem,the best hormone concentration ratio of adventitious bud induction was 1.0 mg/L 6-BA and 0.10 mg/L NAA,and the adventitions bud was healthy.The most suitable hormone concentration for adventitious bud rooting was 0.10 mg/L NAA with 100% rooting rate and 95% survival rate.[Conclusion] The established high efficient regeneration system of T.kok-saghyz has significance on improving tissue culture efficiency and transformation ratio.
