摘要:

为探究外源赤霉素(gibberellic acid, GA3)处理对波尔莱特葡萄及葡萄干品质的影响,设置花期不进行GA3处理(A)、花序盛开75%时进行75 mg·L-1 GA3处理(B)、花序盛开100%时进行75 mg·L-1 GA3处理(C)、花后2 d进行75 mg·L-1 GA3 处理(D)和花后4 d进行75 mg·L-1 GA3(E),以上5种处理均在花后10 d时用150 mg·L-1 GA3 进行处理,以花期和花后10 d均不进行GA3处理为对照(CK),测定葡萄、葡萄干品质及产量指标。结果表明,GA3处理可显著增大波尔莱特葡萄果穗、果粒质量,提高鲜果硬度,但会显著降低可溶性固形物含量;经GA3处理的波尔莱特葡萄所制葡萄干单粒质量显著增大,酚类物质含量及抗氧化活性提高,但饱满度降低、褐变度增大;花期GA3处理可显著增大葡萄及葡萄干果形指数,促进葡萄及葡萄干色泽变绿。D处理的葡萄干产量最高,为12.56 t·hm-2,葡萄干单粒质量最大,为1.30 g,果形指数2.42,较饱满。主成分分析结果直观地反映了各处理葡萄及葡萄干品质、产量分布状况,建立综合评价模型得出D处理综合得分最高。波尔莱特葡萄采用花后2 d施GA3 75 mg·L-1+花后10 d施GA3 150 mg·L-1处理效果最优。以上研究结果为进一步优化和规范波尔莱特葡萄GA3使用技术、提升葡萄及葡萄干品质提供技术参考。

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.
