| Abstract | ||||
| The experiment was conducted at Khatatba, Monofia Governorate during 2003 to 2005 seasons, to study the effect of spraying Ruby Seedless grapevines by lime alone at 3 glitter after two weeks of berry set, CaClz at 3 glliter after three weeks of berry set or lime followed by calcium one week later. Cluster weight, berry weight and size were significant increased with lime and CaClg treated one week later, but with lime alone or CaClz alone, the increment was not significantly at all seasons. However number of berries per cluster did not differ while in the second season was a significant reduction compared to control. Total soluble solids and berry firmness were significant increased compared to control in all seasons of the study, but TSS was insignificant with the lime alone in the third season. Acidity was significant lower with the lime followed by CECI2. However, with lime alone or CaCiz alone in the first and third seasons, but did not in the second season. The effect on leaf area and leaf chlorophyll a, b contents were insignificant. Lime followed by CaClz significantly increased the specific leaf weight, pruning weight, carbohydrate content of basal cane (3 nods), although the increment was insignificant with lime alone or CHOIz alone. The highest berries quality and wood maturity were occurred with spraying Ruby Seedless grapevines with lime 3 gfliter after two weeks of berry set followed by CaClz 3 glLiter three weeks after berry set. | ||||
