摘要: 研究了GA3 等5种植物生长调节剂对睡莲切花的保鲜效应。结果表明:GA350 mg·L-1 处理的保鲜效果最佳,能增大花径,使花茎挺直和延长切花开放时间,有利于维持花枝鲜样质量,减缓花瓣pH值和膜相对透性上升的幅度,从而延长瓶插寿命。PP333 10 mg·L-1 和CCC 10 mg·L-1 处理的保鲜效应不显著。6-BA 1 mg·L-1 和NAA 1 mg·L-1 瓶插处理不适用于睡莲切花保鲜。

Abstract: Efects of diferent plant growth regulators on the vase life and preserving property of Nymphaeft stellata cut flower were studied.The results showed that 50 mg·L-1.GA3treatment produced the best resuit for the preserving property of N.stellata cut flower and could extend the vase、ire of N.stellata cut flower highly significantly as compared to the control(distilled water).It could increase flower diameter,straightened flower stems and prolonged time of the existance of flowers.It also could keep fresh mass of flower stem and retarded the increase of pH value and relative plasmalemma permeability in petals of stellata cut flower.Efects of 10 mg·L-1 PP333 and 10 mg·L-1 CCC treatment were not significantly as compared to the control1 mg·L-1 6-BA and 1 mg·L-1 NAA treatment were not suitable for vase-holding of N.stellata cut flower.
