摘　　要：2003～2004和2004～2005年两个冬季，在四川省攀西地区对霞多丽、佳美、梅鹿辄、黑虎香四个葡萄品种休眠冬芽进行了化学药剂处理。翌年抽枝率结果表明：在冬季气温最低时处理四个品种的抽枝率均有提高；1．0％H2CN2＋1．0％吐温80处理抽枝率提高最大；葡萄品种成熟期不同，对化学药剂处理的反应亦不相同，品种按处理与对照的萌芽率比值大小排序，依次为早中熟品种佳美、中熟品种梅鹿辄、早熟品种霞多丽、晚熟品种黑虎吾。In the winter of the years from 2003 to 2004 and 2004 to 2005, dormant buds of four grapevine eultivars grown in Panzhihua were treated immediately after pruning with budbreaking chemicals. The data of next year＇s shooting percentage indicate that the best time to treat is the time of lowest temperature in winter and 1.0 % H2CN2 ＋ 1.0% Tween 80 have the best effects of improving shooting percentage. Moreover, four wine grapevine eultivars with different maturity phase have different effects of improving shooting percentage when treated with budbreaking chemicals. From the first to the last, the list of eultivars is early ripe Chardon- ny, early-mid ripe Gamay and mid-late Merlot, late ripe Fox according to the improving shooting percentage.
