Paclobutrazol is classified chemically in the family of triazoles (Diterpenoid carboxylic acids) and is considered one of the growth regulators and plant hormones such as gibberellin and abscisic acid, that are used as sprays on grapevines to improve vegetative characteristics and yield quality. This study was carried out during the 2018/2019, 2019/2020, and 2020/2021   seasons to examine the effect of spraying Paclobutrazol on the superior grapevine. Application of Paclobutrazol at three levels (0, 500, and 1000 ppm) at the time of bud burst. Results showed a reduction in total shoot and bud numbers, increased fruit set, and increased berry weight, fruit yield, and fruit quality for all PBZ treatments compared to the control. The yield was harvested on the third week of June. The main objectives of this work are to study the impacts of Paclobutrazol on earlier, improved berry quality, and increased yield of superior seedless grapes for exportation.
