Abstract:
      In the winter of the years from 2003 to 2004 and 2004 to 2005,dormant buds of four grapevine cultivars 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 cultivars 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 cultivars is early ripe Chardonny,early-mid ripe Gamay and mid-late Merlot,late ripe Fox according to the improving shooting percentage.
