- 摘要:
- 为不断完善兜兰属植物人工繁育技术体系,本文以白花兜兰、小叶兜兰和亨利兜兰自然成熟的果荚为材料,进行无菌播种和快繁技术研究。结果表明:常规的组培快繁消毒技术,对3种兜兰的果荚消毒具有较好的效果;培养基1/2MS+土豆汁100 mg?L-1+ 活性炭1 g?L-1比较适合白花兜兰种子的萌发,小叶兜兰和亨利兜兰也能有较好的萌发效果;无菌播种后,前期的暗培养有利于白花兜兰的萌发;相较小叶兜兰和亨利兜兰,白花兜兰的种子萌发一致性较差,在继代过程中极易出现死亡现象。本研究对兜兰属植物的保护和人工繁育具有一定的参考价值。
- Abstract:
- In order to improve the artificial breeding technology system of the genus polygonu,in this article,the naturally matured pods of Paphiopedilum emersonii,P.barbigerum,P.henryanum were collected for sterile germination and rapid propagation.The results showed that:regular disinfection technology of tissue culture and rapid propagation had good performance.The media 1/2MS+potato juice 100 mg?L-1+ acticarbon 1 g?L-1 was suitable for seed germination of P.emersonii,and it also had good germinating effect on Paphiopedilum microphylla and Paphiopedilum henryi.Keeping darkness in the early stage of the seed germination was good for P.emersonii.Compared to P.barbigerum and P.henryanum,it was relatively hard to cultivate P.emersonii,including problems as germination inconsistency and seedling death in the secondary culture stage.This research had some reference value for Paphiopedilum in conservation and artificial breeding.
