| Abstract | ||||
| The experiment was conducted at El-Mahala City, Gharbia Governorate, Egypt, during 2016/2017 and 2017/2018 growing seasons on 12-year-old "Crimson"seedless grape vines to find cheap alternatives to hydrogen cyanamide to help regularize the sprouts in the grapes of the Crimson variety, in addition study of the effect of these alternatives and hydrogen cyanamide on the behavior of grapevine grapes.Crimson seedless grape with the combination treatment of Dormex (2.5%) + Flaxseed oil (2.5 %) + ZnSO4 (0.5%) + urea (2.5 %) produced the highest percentages of bud burst and fertility,total sugars and glutathione content and the same time the lowest percentages of crude protein and total phenols content in buds in both seasons.The best treatment for increasing vegetative growth characters,physical characteristics of clusters and berries, chemical constituents of Crimson seedless grape berries and yield (yield/vine and yield/feddan)was obtained when treating Crimson seedless grapevines with the combination treatment of Dormex (2.5%) + flaxseed oil (2.5 %) + ZnSO4 (0.5%) + urea (2.5 %), which resulted in the highest values of these traits in both seasons. | ||||
