外源激素及内源激素对黄瓜果实发育的影响
Effects of Exogenous Hormone Treatments on the Fruit Development of Cucumber and Analysis on its Endogenous
摘要
Abstract
[Objective] The purpose was to study the effects of hormone on the fruit development of cucumber. [ Method] The young cucumber fruit of flowering day was treated with exogenous hormones by painting and its fruit-setting rate was investigated. The content variation of endogenous hormones in the development process of treated fruit was analyzed by HPLC method. [ Result] The natural fruit-setting rates of cucumber in the 2 investigations were 15.1% and 25.7% resp. And that of cucumber treated with GA,6-BA and forchlorfenuron were 43.7% ,68.3% and 89. 2% resp. Indicating that cytokinin could enhance the fruit-setting rate of cucumber significantly,especially for forchlorfenuron,and GA possessed some promoting effect on fruit-setting. During the development process of fruit,the contents of endogenous growth hormone and cytokinin were being reduced along with the increase of developing days and the content of GA was higher on the 3rd and 6th days since flowering. The content of GA in the variety of fast fruit-developing was higher than that in the variety of slowly fruit-developing. [ Conclusion] This study supplied direction basis for the application of hormone substance in the cultivation and production of cucumber.关键词
