| Abstract | ||
| The fusion of developmental events depends heavily on phytohormones. The physiological consequences of active gibberellins vary based on the gibberellin GA3 type found in the grapevine plant. During the 2018/2019, 2019/2020, and 2020/2021 seasons superior grapevines were sprayed with GA3 at concentrations (0, 10, 20, and 40 ppm) at the pea stage “6 mm” to study its effect on vegetative growth and yield. All treatments had a positive impact on increasing the studied vegetative growth while at the same time increasing yield/treatment and cluster weight, improve the berry quality, and other parameters. The main objectives of the research are delaying the ripening of grapevine clusters, and thus prolonging the period of harvesting the crop and obtaining it for long periods, which brings great economic benefit, and obtaining a grape crop with export specifications in terms of the quality of grape clusters and berries. This is a natural storage of the fruits for a date later than the normal date, which brings a profitable economic return to the farmer. | ||
