多肉植物红宝石组织培养快繁技术

    Rapid Propagation of Sedeveria Pink Ruby by Tissue Culture

    • 摘要: 为建立多肉植物红宝石高效组织培养快繁技术体系,为工厂化生产提供技术保障。以多肉植物红宝石的幼嫩叶片作为外植体,进行多肉植物红宝石组培快繁技术研究。结果表明:采用75%酒精浸泡60 s,再使用0.1%升汞处理10 min是红宝石外植体最佳消毒处理方法。红宝石愈伤组织诱导的最适培养基为MS+6-BA 1.5 mg·L-1+NAA 0.5 mg·L-1(pH=6.0),诱导率可达83.3%;愈伤组织分化成芽的最适培养基为MS+6-BA 0.6 mg·L-1+NAA 0.2 mg·L-1(pH=6.0),分化率可达77.78%;生根最适培养基为1/2 MS+活性炭2.0 g·L-1(pH=6.0),生根率可达70.00%。

       

      Abstract: In order to establish the rapid propagation technology system of Sedeveria pink ruby by high-efficient tissue culture, and provide the technical support for industrialized production, the tissue culture and rapid propagation technology of Sedeveria pink ruby was studied by using the young leaves of Sedeveria pink ruby as the explants. The results showed that 75% alcohol soaked for 60 s and 0.1% mercury bichloride treated for 10 min were the best disinfection treatments for the explants of Sedeveria pink ruby. The optimal culture medium for callus induction of Sedeveria pink ruby was MS+1.5 mg·L-1 6-BA+0.5 mg·L-1 NAA (pH=6.0), with the induction rate of 83.3%. The optimum culture medium for bud differentiation from callus was MS+0.6 mg·L-1 6-BA+0.2 mg·L-1 NAA (pH=6.0), with the differentiation rate of 77.78%. The optimal culture medium for rooting was 1/2 MS+2.0 g·L-1 activated carbon (pH=6.0), and the rooting rate could reach 70.00%.
