Effects of Sucrose Spraying on Sugar Metabolism in Leaves of'Marselan'Grape
摘要
Abstract
Taking'Marselan'grape as the test material,the effects of spraying different concentrations of sucrose on the sugar metabolism of'Marselan'grape leaves were studied by setting different concentrations of sucrose for spraying,the photosynthetic parameters,leaf area,sugar components and sugar metabolism related enzyme activities of grape leaves at 5 days,35 days,65 days,90 days and 115 days after flowering were determined,in order to provide reference for grape production.The results showed that compared with the control,the SPAD value of the leaves of'Marselan'grape leaves increased,the leaf area increased,the photosynthetic parameters changed at different times and concentrations,and the carbohydrate content and sucrose metabolizing enzyme activities increased after sucrose spraying.Compared with CK,the SPAD value,Pn and Tr of leaves increased by 19.67％,85.63％and 69.51％,respectively,under T2 treatment 5 days after anthesis.At the same time,the sucrose synthase(SS)and neutral invertase(NI)in leaves increased by 80.94％and 386.01％,respectively,under T3 treatment.The leaf area under T3 treatment increased by 39.60％compared with CK at 115 days after flowering.On the 35th day after anthesis,the soluble sugar of glucose leaves under T2 treatment was significantly increased by 103.33％compared with the control.In conclusion,the spraying of exogenous sugar sucrose promoted the glucose metabolism of'Marselan'grape leaves,and the experimental results showed that T2(0.17 mol·L-1)treatment was the most beneficial to the glucose metabolism of grape leaves.关键词
