Effects Of Different Puffing Measures On The Fruit Quality Of 'Summer Black' Grapes

In this experiment, the effect of GA(3) + CPPU on the quality of 'summer black' grape was studied. The results showed that the combination of GA(3) and CPPU (1-2d: 4Oppm GA(3) + 2ppm CPPU, 12-14d: 5Oppm GA(3) + 6ppm CPPU) was better than the combination of GA(3) and CPPU (12-14d: 5Oppm GA(3) + 6ppm CPPU), which could increase the weight of ear and single fruit, increase the vertical and horizontal diameter of fruit grain and fruit shape index, and had better coloring, but decreased the fruit shape index Solid acid ratio.
