以夏黑葡萄为试材，在盛花期分别以30、40、50 mg/L GA3浸蘸花穗，花后两周以30、40、50 mg/L GA3外加1、3、5 mg/L TDZ浸蘸果穗，以二次处理时50 mg/L GA3＋5 mg/L CPPU为对照，研究不同激素组合处理对夏黑葡萄果实生长及果实品质的影响。结果表明：盛花期50 mg/L GA3，花后两周50 mg/L GA3＋3 mg/L TDZ处理的效果最好，既增加了果实重量和可溶性固形物含量，也降低了果实可滴定酸含量，同时显著促进了果皮花青苷含量的提高，果皮的着色指标L、a、b和h值均较对照差异显著；盛花期30 mg/L GA3，花后两周30 mg/L GA3＋1 mg/L TDZ处理除了单果重略低于对照，在品质方面均显著优于对照；TDZ的作用效果要优于CPPU。

The flower spikes of summer black grapes at full -bloom stage were respectively dipped into 30, 40, 50 mg/L GA3 , and their fruit spikes were dipped into the combined solutions of 30, 40, 50 mg/L GA3 plus 1, 3, 5 mg/L TDZ two weeks after flowering.The application of 50 mg/L GA3(the first-step treatment) plus 50 mg/L GA3 +5 mg/L CPPU (the second-step treat-ment) was taken as the control , and the effects of different hormone combination treatments on the fruit growth and quality of sum -mer black grapes were studied .The results revealed that the application of 50 mg/L GA3 at full-bloom stage plus 50 mg/L GA3 +3 mg/L TDZ two weeks after flowering had the best effect , it not only increased fruit weight and soluble solids content , reduced the titratable acid content in the fruit , but also significantly promoted the improvement of the anthocyanin content in the pericarp , and its pericarp color indicators L , a, b and h values were significantly different from those in the control .In addition , the treatment with 30 mg/L GA3 at full-bloom stage plus 30 mg/L GA3 +1 mg/L TDZ two weeks after flowering obtained significantly better fruit quality ( except slightly lower single -fruit weight ) than the control;the effect of TDZ was better than CPPU .
