In order to study the effects of CPPU and GA3 on fruit quality and quantity of Sultanina grapes, a factorial experiment in a randomized complete block design was implemented in a commercial vineyard near Bonab city (West Azerbaijan province). The spraying was done at fruit set stage using CPPU and gibberellic acid. According to the results, it was found that these plant growth regulators had a significant effect on the diameter and length of the berry, weight, dry matter and moisture, the red value and shrinkage of the fruit while these treatments did not affect the pH and acidity of the fruit. Also, the interaction between growth regulators showed a significant effect on vitamin C content and berry size. Gibberellic acid reduced the level of brix, dry matter percent and the red color value and Increased berries shrinkage In contrast, treatment with 7.5 mg CPPU Not have adverse effects of gibberellic acid and It seems to be an appropriate treatment to improve fruit quality and quantity of Sultanina grapes in the vineyards of the region and can be suggested for both fresh consumption and raisin production.
