Abstract: 

Introduction: The basic characteristic of modern table grape production is its adaptation to the requirements of the market aiming to improve grape quality, such as equal cluster size, equal size and shape of the berry, and equal coloration of all the berries in the cluster. Furthermore, an important attribute of the grape berry quality is seedlessness. Seedless cultivars are characterized with small berries, which can be increased by using some management techniques. Plant hormones may play an important role in the growth and development of grape berries. Gibberellic acid (GA3) is known to stimulate development of parthenocarpic fruit in grapes and other fruits. The exogenous pre-bloom application of GA3 to grapevine is commonly used to induce seedlessness, accelerate early ripening, and enhance berry size in seedless cultivars. Although there are a large number of studies on seedless grape varieties, no previous research has been performed on the effect of GA3 on the seeded grape cultivars. Differences in the types of berry set affect the growth of berries and their size. It is well known that there is an important relationship between seed development and berry growth, which has been attributed to hormones such as auxins, gibberellins and cytokinins...
