以金焰绣线菊带有分蘖芽的茎段为材料,进行了生根、继代、移栽以及定植的研究,建立起金焰绣线菊的快速繁殖体系,从而加快其繁殖速度,满足栽培的需求。结果表明:1/2MS+蔗糖12 g/L+ ABT2号1.5mg·L -1+IBA0.2mg·L -1是带有分蘖芽的茎段试管苗生根和试管苗生根继代繁殖培养的适宜培养基。试管苗移栽成活率为97.3%,定植成活率为99.5%。定植的试管苗植株整齐、生长旺盛,不仅保持了金焰绣线菊的植物特征,也保持了较好的观赏效果。
以金燄繡線菊帶有分蘗芽的莖段為材料,進行瞭生根、繼代、移栽以及定植的研究,建立起金燄繡線菊的快速繁殖體繫,從而加快其繁殖速度,滿足栽培的需求。結果錶明:1/2MS+蔗糖12 g/L+ ABT2號1.5mg·L -1+IBA0.2mg·L -1是帶有分蘗芽的莖段試管苗生根和試管苗生根繼代繁殖培養的適宜培養基。試管苗移栽成活率為97.3%,定植成活率為99.5%。定植的試管苗植株整齊、生長旺盛,不僅保持瞭金燄繡線菊的植物特徵,也保持瞭較好的觀賞效果。
