3-year-old Summer Black grape was conducted to study that the influences of different times, concentrations and combinations of plant growth regulator on the berry enlargement and quality in winter fruits. The results showed that the treatment with 50 mg/L GA3 during full bloom, 50 mg/L GA3+Yiguoling 2 mg/L after 5 days, 50 mg/L GA3+Yiguoling 3 mg/L after 10 days had better enlargement effect, but fruit quality had no significant effect compared to the control. The berries after treatment got the hundred-berry weight up to 740.46 g, the soluble solids up to 17.6%, and the total soluble sugar up to 166.12 g/L.%本试验以3年生夏黑葡萄为试材，研究了不同处理时间、不同浓度和不同植物生长调节剂组合处理对夏黑葡萄冬果膨大及品质的影响。结果表明，对夏黑冬果进行药剂膨大处理，从果实综合性状来看，盛花期使用50 mg/L GA3，花后5 d用50 mg/L GA3+益果灵2 mg/L，花后10 d用50 mg/L GA3+益果灵3 mg/L进行蘸穗处理膨大效果较好，果实品质与对照差异不显著，且副效应较小，百粒果质量740.46 g，可溶性固形物为17.6%，可溶性总糖为166.12 g/L。
