以紫花山柰无菌苗的芽基部为外植体,对芽基部进行继代增殖、丛生芽诱导以及生根培养基的筛选,建立了紫花山柰无菌苗芽基部的组培快繁体系。结果表明:紫花山柰无菌苗芽基部继代增殖比较合适的培养基为MS+6-BA 8~12 mg/L+ NAA 0~0.1 mg/L +椰汁10%+白砂糖30 g/L +卡拉胶粉10 g/L,最佳继代增殖培养基为MS+6-BA 8 mg/L+NAA 0.1 mg/L+椰汁10%+白砂糖30 g/L+卡拉胶粉10 g/L;丛生芽诱导较合适的培养基为MS+6-BA 3~5 mg/L+NAA 0.05~0.1 mg/L+椰汁10%+白砂糖30 g/L+卡拉胶粉10 g/L,最佳的丛生芽诱导培养基为MS+6-BA 3 mg/L+NAA 0.05 mg/L+椰汁10%+白砂糖30 g/L+卡拉胶粉10 g/L;生根较佳的培养基为MS+NAA0.1 mg/L+香蕉泥10~15%+活性炭0.5~1.0 g/L+白砂糖30 g/L+卡拉胶粉9.5 g/L。 |
英文摘要: |
The shoot bases of Kaempferia elegans sterile seedlings were used as explants which were subcultured for propagation, induced for multiple shoots, and rooted to produce rooted plants, and their medium for tissue culture were screened to establish a rapid propagation system for K. elegans. The results showed that the appropriate medium for propagation of K. elegans were MS+6-BA 8~12 mg/L+NAA 0~0.1 mg/L+coconut milk 10%+sucrose 30 g/L+cara rubber powder 10 g/L, and the best propagation medium was MS+6-BA 8 mg/L+NAA 0.1 mg/L+coconut milk 10%+sucrose 30 g/L+cara rubber powder 10 g/L. The suitable medium for inducing multiple shoots were MS+6-BA 3~5 mg/L+NAA 0.05~0.1 mg/L+ coconut milk 10%+ sucrose 30 g/L+ cara rubber powder 10 g/L, and the most suitable medium for inducing multiple shoots was MS+6-BA 3 mg/L+NAA 0.05 mg/L+ coconut milk 10%+ sucrose 30 g/L+ cara rubber powder 10 g/L. The optimum rooting medium was MS+ NAA 0.1 mg/L+ mashed banana 10~15%+activated carbon 0.5~1.0 g/L+ sucrose 30 g/L+ cara rubber powder 9.5 g/L. |
