摘　　要：以1a生"无核白鸡心"葡萄为试材,研究了新梢花后不同阶段短梢修剪对葡萄花芽分化及叶片营养物质含量的影响。结果表明:短梢修剪后,冬芽迅速进入花器官分化阶段,修剪Ⅱ(花后30d进行短梢修剪)、修剪Ⅲ(花后40d进行短梢修剪)处理效果最好,提高了叶片可溶性糖含量,降低了叶片全氮含量,处理5d后50%以上的冬芽进入了花器官分化阶段。Taking 1-year-old ＇Centennial Seedless＇ grape as material, the variation of flower bud differentiation and nutrient content in leaf were studied through leaving four buds pruning after full bloom. The results showed that the winter buds accessed to floral organ differentiation rapidly after pruning, of which, treatment II（pruning 30 days after anthesis on shoots） and Ⅲ （pruning 40 days after anthesis on axillary shoot）were better than the other treatments, in which above 50% winter buds entered the floral organ differentiation stage after 5 days of treatment. Soluble sugar contents in leaf increased,and total nitrogen content decreased.
