| 摘 要： | [目的]探讨表油菜素内酯对香石竹切花活性氧代谢的影响，为香石竹切花保鲜提供参考。[方法]用表油菜素内酯和活性氧清除剂甘露醇处理切花，以清水为对照，比较其对香石竹切花活性氧代谢的影响。[结果]与甘露醇相比，表油菜素内酯能有效地增大花径，提高超氧化物酶、过氧化氢酶活性，延缓O2·产生速率，H2O2含量、MDA含量和膜相对透性上升的幅度。[结论]表油菜素内酯能有效缓解切花活性氧的产生与积累，提高活性氧清除能力，从而延长瓶插寿命。，

| Abstract: | [Objective]The study aimed to discuss the effect of epibrassinolide on active oxygen metabolism and provide the reference for fresh-keeping of cut carnation(Dianthous caryophyllus L.) flower.[Method]With clear water as CK,the cut flowers were treated by epibrassinolide and active oxygen scavengers(mannitol).We study the effect of two different treatments on some physiological indexes of active oxygen metabolism.[Result]The results showed that the level of active oxygen metabolism during the senescence of cu... |
