Abstract：Inorderto investigate the effect of exogenousgibberellicacid（ GA3 ）treatment on thequalityofPerlette grapes andraisins，5 treatments were set including no GAtreatment during bloom（A），inflorescence 75% blooming with 75 mg* L-1 GA3 treatment（B），inflorescence 100% blooming with 75 mg·L-1 GA 3 treatment（C），2 d post-bloom with 75 mg L-1GA3 treatment（D），and 4d post-bloom with 75 mg* L-1 GA 3 treatment（E）.All the above treatmentswere treated with GA 150 mg* L-1 at 10 d post-bloom，and no spraying GA3 during bloom and post-bloom was as the control（CK）， beries quality，raisin quality and yield were assessed.Theresults showed that berry mass，cluster mass and berry hardness of Perlette grape was significantly increase by GA3 treatment，but the total soluble solids content was significantly decreased.The single raisin masswas significantly increased by GA 3 treatment，phenoliccontentand antioxidant activity were enhanced，but plumpness was decreased，browning was decreased.The shape index of grapesand raisins were significantly increasedby GA3 treatment during bloom，and promoted the color of grapes and raisins turn to green.The yield of raisins and the single mass of raisins were the highest in treatment D，with 12.56t⋅hm-2 ， 1.30g ，respectively， andthe raisin shape index was 2.42，relativelyplump.Theresultsof principal componentanalysis intuitivelyreflect the qualityand yield distributionof grapes andraisins in each treatment.A comprehensiveevaluationmodelwas established， and it was found that treatmentDhadthehighestcomprehensivescore.Thebestefect was treatmentof2d post-bloom with 75mg·L -1 GA3+10 d post-bloom with 150mg*L-1 GA3 .Above resultsprovided technical reference for further optimizing and standardizing the use of GA3 inPerlette grapes，and improved the quality of grapes and raisins.
