| 摘 要： | 目的]探讨外源激素水平等对洋桔梗愈伤诱导、不定芽分化、继代增殖、生根的影响,以建立其组织培养工厂化育苗生产体系。方法]通过无菌插种获得无菌苗,取其带腋芽茎段为外植体,采用随机区组试验筛选愈伤形成、不定芽分化、增殖与不定根形成的适宜激素水平。结果]适宜洋桔梗愈伤与不定芽分化的培养基为MS＋6-BA 0.1～0.5 mg/L＋NAA 0.1～0.5 mg/L;继代增殖适宜培养基为MS＋6-BA 0.1～0.5 mg/L＋NAA 0.1～0.5 mg/L＋GA 0.1～0.5 mg/L＋干酪素50～100 mg/L;生根适宜的培养基为1/2MS＋NAA 0.1～0.3 mg/L或IBA 0.5 mg/L或IAA 0.5 mg/L,25 d内生根率可达95%以上;在蛭石∶珍珠岩∶腐叶土=4∶4∶2基质中驯苗,成活率可达96%以上。结论]利用组织培养技术对洋桔梗进行快速繁殖,实现其工厂化育苗具有重要的现实意义。
