摘要
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。
The decrease in leaf area per berry led to lower average berry weight, coloration and °Brix in kyoho grapevines. The proper leaf area for berry growth and development in the shoots of single clusters and double clusters were 70～100cm^2 and 40～60cm^2 per berry respectively. The nutrient for berry growth was mainly supplied by photosynthetic products from the same lateral leaves with the clusters. The leaf area per berry was related positively to berry weight and °Birx.
