GA3和 CPPU 对“醉金香”葡萄果实无核化及品质的影响

摘要

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 size with golden skin, and total soluble solids content reached to 17.9%.%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％。
