GA_3和CPPU处理对‘藤稔’葡萄果实的影响

Effects of GA_3 and CPPU Treatments on Fruit Quality of ‘Fujiminori' Grape Variety

以‘藤稔’葡萄为试材,开花后1周喷施GA_325 mg/L和GA_325 mg/L+CPPU 5 mg/L,研究其对果实生长的影响。结果表明,GA_325 mg/L和GA_325 mg/L+CPPU 5 mg/L处理较对照显著提高果穗重、果粒重、果粒着色率、果柄粗度,减少果蒂粗度、果刷粗度;GA_325 mg/L有利于增加果刷长度。

GA3 25 mg/L and GA3 25 mg/L＋CPPU 5 mg/L were sprayed on ＇Fujiminori＇ grape one week after flowering to study their effects on fruit growth. The results showed that GA3 25 mg/L and GA325 mg/L＋CPPU 5 mg/L treatments significantly increased the fruit ear weight, grain weight, fruit coloring rate and stem diameter,reduced pedicel thickness and brush thickness,and GA3 25 mg/L was beneficial to increase fruit brush length.
