苹果不同角度结果枝组对果实品质与叶片营养物质含量的影响
Effect of Different Yielding Shoot Group Angle on the Branch Nutrients and Fruit Quality of Apple
摘要
Abstract
In this paper ,we studied the effects of different angle of yielding shoot group on fruit quality and leaf nutrient ,using vigorous Fuji as materials .The results showed that the indicators of fruit quality ,soluble solids ,total soluble sugar and coloring index were higher when the fruit on yielding shoot group was in treatment Ⅲ (91°-180°) .Moreover ,in treatment Ⅲ leaf net photo-synthetic rate was higher ,photosynthetic products assimilated faster ,and the accumulation of mineral elements in leaves ,single leaf fresh weight ,leaf thickness ,chlorophyll content ,and other traits were better than with other treatments .Correlation analysis showed that hardness and leaf fresh weight ,leaf chlorophyll content and net photosynthetic rate were positively correlated ,with the correlation coefficients of 1 .00 ,1 .00 and 0 .99 ;the fruit weight was positively correlated to leaf thickness and significantly with the chlorophyll content ,with the correlation coefficients of 1.00 and 0 .98 ;the fruit Vc content was positively correlated to leaf thickness with the correla-tion coefficient of 0 .98 .关键词
