摘　　要：为筛选出‘着色香’葡萄使用植物生长调节剂的最佳时期,本试验以7年生‘着色香’葡萄为试材,研究了不同时期两种植物生长调节剂赤霉素(GA_(3))和氯吡脲(CPPU)组合处理对果实品质的影响。结果表明:使用GA_(3)+CPPU组合处理改善了‘着色香’葡萄果实的品质,其中以初花期、盛花期使用25~50 mg·L^(-1)GA_(3)+2 mg·L^(-1)CPPU+花后15 d使用25~50 mg·L^(-1)GA_(3)+2 mg·L^(-1)CPPU效果较好,其果穗重、果粒重、可溶性固形物、可溶性糖含量均较对照显著提高,可滴定酸含量显著低于对照。In order to select the best period for‘Zhuosexiang’grape to use plant growth regulators,7-year-old‘Zhuosexiang’grape was used as test materials,to study the effects of two growth regulators combination treatments(GA_(3) and CPPU)at different period on fruit qualitg of‘Zhuosexiang’grape.The results showed that combination treatments(GA_(3) and CPPU)at different period all improved quality of‘Zhuosexiang’grape,it was better to treatments of 25-50 mg·L^(-1)GA_(3)+2 mg·L^(-1)CPPU was used in initial flowering stage and full-bloom stage+25-50 mg·L^(-1) GA_(3)+2 mg·L^(-1)CPPU was used 15 days after flowering.Cluster weight,berry weight,solublesolids,soluble sugar content increased respectively,while titratable acid content decreased respectively.
