| 摘 要： | 以玉花兰的根状茎为外植体,研究了引起玉花兰根状茎绿芽分化的各种因素.结果表明:Hyponex-2培养基有利于玉花兰绿芽的分化,而且诱导芽数多,生长良好.6-BA促进绿芽的形成,且在浓度为4mg/L时效果最佳;选择根状茎的上部作为外植体时,绿芽分化较好;在绿芽分化阶段,采用400lx的光照条件培养比较适宜;Hyponex-2培养基中添加浓度为1.0mg/L的NAA有利于根的诱导,同时也能促进地上部的生长发育. |
| 关 键 词： | 玉花兰 组织培养 根状茎 绿芽 生根 |

| Abstract: | Factors in rhizome differentiation of Cymbidum niveo-maginatum were studied in this paper.The results showed that shoot formation was favorable in Hyponex-2(N∶P∶K=20∶20∶20)medium and mass shoots were found in this medium.Moreover,BA 4 mg/L in Hyponex-2 medium and 400 lx of light intensity promoted shoot formation of Cymbidum niveo-maginatum.During rooting stage,NAA 1.0 mg/L was suitable for rooting and shoot growth. |
| Keywords: | Cymbidum niveo-maginatum Tissue culture Rhizome Shoot Rooting |
