东方百合‘Vivian’高效离体快繁体系的建立

Establishment of an Efficient Approach in Vitro Propagation for Oriental Hybrid Lily Cultivar ‘Vivian’

  • 摘要: 以东方百合‘Vivian’的鳞片为外植体,对不定芽的诱导、增殖、小鳞茎膨大及生根等进行系统研究,建立了高效离体快繁体系。结果表明:东方百合‘Vivian’的最佳不定芽诱导培养基为MS+1.0 mg·L−1 6-BA+0.1 mg·L−1 NAA+30 g·L−1蔗糖+6.0 g·L−1琼脂,pH值为6.0;最佳不定芽增殖培养基为MS+1.0 mg·L−1 6-BA+0.15 mg·L−1 NAA+60 g·L−1蔗糖+6.0 g·L−1琼脂,pH值为6.0;最佳小鳞茎膨大培养基为MS+90 g·L−1蔗糖+6.0 g·L−1琼脂,pH=6.0;最佳生根培养基为1/2 MS+0.3 mg·L−1NAA+60 g·L−1蔗糖+6.0 g·L−1 琼脂,pH值为6.0;在草炭与蛭石比例为1∶1的基质中的组培苗移栽苗长势健壮且成活率最高达95.31%。该高效离体快繁体系可为东方百合‘Vivian’的规模化生产提供技术保障。

     

    Abstract: In order to develop an efficient approach for the rapid propagation of Oriental hybrid lily cultivar ‘Vivian’ by tissue culture, the scales were used as the explants. The results showed that the best adventitious bud induction medium of Oriental hybrid lily cultivar ‘Vivian’ was MS+1.0 mg·L−1 6-BA+0.1 mg·L−1 NAA+30 g·L−1 sucrose+6.0 g·L−1 agar, and pH value was 6.0. The optimal medium for adventitious bud proliferation was MS+1.0 mg·L−1 6-BA+0.15 mg·L−1 NAA+60 g·L−1 sucrose+6.0 g·L−1 agar, and the pH value was 6.0. The best medium for bulblet expansion was MS+ 90 g·L−1 sucrose+6.0 g·L−1 agar, with pH value of 6.0. The optimal medium for bulblet rooting was 1/2 MS+0.3 mg·L−1 NAA+60 g·L−1 sucrose+6.0 g·L−1 agar, and the pH value was 6.0. Transplanted tissue culture seedlings in the substrate of the ratio of peat to vermiculite of 1∶1 growed vigorously and the survival rate was up to 95.31%. This efficient in vitro rapid propagation system can provide technical support for large scale production of Oriental hybrid lily cultivar ‘Vivian’.
