摘　　要：Solutions of gibberellic acid prepared at three concentration levels including 5, 10 and 20 mg/L, were applied at two seedless grape varieties, Thompson and Belgrade, by spraying, during the three different periods of the vine growing： before blooming, after blooming and before veraison, in order to study their influence on some cultural technological characteristics. Dimension and shape of the cluster and berry, mechanical characteristics of the berries and chemical content of the must （sugar and total acids） has been also investigated. It was noticed that the concentration of gibberellic acid had influence on the technological characteristics of the berries in all grape growing periods tested. The addition of gibberellic acid at concentration of 20 mg/L increased the weight of the cluster and berry, and increased the transportability of the berries belonging to the two seedless varieties.
