赤霉素处理对波尔莱特葡萄及葡萄干品质的影响
Effects of Gibberellic Acid on Berry and Raisin of Perlette Grape
摘要
Abstract
In order to investigate the effect of exogenous gibberellic acid(GA3)treatment on the quality of Perlette grapes and raisins,5 treatments were set including no GA3 treatment during bloom(A),inflorescence 75%blooming with 75 mg·L-1 GA3 treatment(B),inflorescence 100%blooming with 75 mg·L-1 GA3 treatment(C),2 d post-bloom with 75 mg·L-1 GA3 treatment(D),and 4 d post-bloom with 75 mg·L-1 GA3 treatment(E).All the above treatments were treated with GA3 150 mg·L-1 at 10 d post-bloom,and no spraying GA3 during bloom and post-bloom was as the control(CK),berries quality,raisin quality and yield were assessed.The results 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 mass was significantly increased by GA3 treatment,phenolic content and antioxidant activity were enhanced,but plumpness was decreased,browning was decreased.The shape index of grapes and raisins were significantly increased by 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 12.56 t·hm-2,1.30 g,respectively,and the raisin shape index was 2.42,relatively plump.The results of principal component analysis intuitively reflect the quality and yield distribution of grapes and raisins in each treatment.A comprehensive evaluation model was established,and it was found that treatment D had the highest comprehensive score.The best effect was treatment of 2 d post-bloom with 75 mg·L-1 GA3+10 d post-bloom with 150 mg·L-1 GA3.Above results provided technical reference for further optimizing and standardizing the use of GA3 in Perlette grapes,and improved the quality of grapes and raisins.关键词
