巨峰葡萄每浆果占有的叶面积,与浆果重、着色和白利糖度含量有密切关系。单果穗新梢和双果穗新梢上浆果生长发育需要的适宜叶面积指标分别为70～100cm~2/浆果和40～60cm~2/浆果。证明浆果生长需要的养分主要来源于与果穗同侧叶片制造的光合产物。每浆果占有的叶面积对浆果重及白利糖度的影响呈显著正相关。 Kyoho grapes per leaf area occupied by berries, and berry weight, color and Brix content are closely related. The suitable leaf area index for the growth and development of single berries and double fruit shoots were 70 ~ 100cm ~ 2 / berry and 40 ~ 60cm ~ 2 / berry respectively. Prove that the nutrients needed for the growth of berries come from the photosynthate produced on the same side of the ear. There was a significant positive correlation between the leaf area occupied per berry and berry weight and Brix content.
