以醉金香葡萄为试材，研究赤霉素（GA3）和吡效隆（CPPU）不同处理浓度和时期对醉金香无核化和品质的影响。结果表明：盛花期以赤霉素20 mg／L 和吡效隆2.5 mg／L 浸花序，15天后再以赤霉素25 mg／L和吡效隆2.5 mg／L 浸果穗的处理效果好。经此处理，穗形整齐美观，穗质量470 g；果粒呈球形，粒质量8.19 g，无核率100％，大小均匀，色泽金黄；可溶性固形物质量分数达17.9％。

Effect of different concentration of gibberellin (GA3 )and forchlorfenuron (CPPU)at different period on seedlessness and berry quality of "Zuijinxiang"grape was studied.The results showed that,applied a concentration of GA3 20 mg/L plus CPPU 2.5 mg/L dipping inflorescence when bloom,then applied GA3 25 mg/L plus CPPU 2.5 mg/L dipping ear after 15 days was an effective method.Through this treatment,ear weight reached to 470 g with a neat ap-pearance,berry was global with weight of 8.19 g,berry was completely seedless and had the same siz...
