摘　　要：以8年生"霞多丽"葡萄为试材,比较分析了不同留叶量及不同时间摘叶处理对葡萄果实品质指标(总糖、总酸、糖酸比、pH、总酚、丹宁)及一年生葡萄枝条的总糖、淀粉含量与茎髓比的影响。结果表明:结果枝留叶量为8或10片时与在葡萄转色后期进行摘叶处理均可明显改善果实层的通透性,显著提高葡萄果实品质,糖度增加,酸度降低,糖酸比、pH均有提高,酚类物质有效合成;不同留叶量与不同时间摘叶处理使树体总糖、淀粉含量及茎髓比均有不同程度的降低,而结果枝留10片叶与转色后期2种处理对果树枝条的碳素营养没有造成显著影响。Eight-year-old ＇Chardonnay＇ grape were used as test material to investigate the effect of different leaf number and different time to remove leaves from fruit branches on grape quality index total sugar, total acid, sugar-acid ratio, pH,total phenols, tannins and total sugar, starch contents and stem-pulp ratio of one-year-old branches. The results showed when 8 or 10 leaves was leaved on single fruit branch and leaf removing of after veraison could improve the fruit surrounding microenvironment significantly, and had improved fruit quality significantly, the total sugar, total phenol, tannin contents,pH and sugar acid ratio increased in different degree,the content of acid decreased, one-year-old branches total sugar, starch content and stem-pulp ratio all decreased after different leaf number and different time removing leaves treatment,but keeping 10 leaves of single branch and leaf removing of after veraison had no significant effect on carbon nutrition of the branches.
