| 摘 要： | 研究了GA3处理对菊花花期、小花数、开花和衰老过程中水分、细胞质膜透性等生理生化指标的影响。结果表明:GA3处理能促进菊花提前开花5d,延长花期7d,增加小花数20.4%。GA3处理能提高菊花开花和衰老过程中花瓣的水分含量,降低细胞质膜透性和丙二醛的含量,提高可溶性糖含量和过氧化物酶、过氧化氢酶的活性,达到延长花期的目的。

| Abstract: | Taking the Chrysanthemum morifoliumm as materials,the effects of GA3 on the flowering and some physiological indexes were studied.The results showed the time of flowering after GA3 treatment were moved ahead for 5 d,the florescence was prolonged for 8 d and the number of small flower was increased for 20.4 % more than those of CK.The water content of petal was increased,the cell membrane relative permeability and MDA content were decreased,the soluble sugar,the activities of POD and CAT were increased during the florescence. |
