Fruiting Evaluation of the First to Twelfth Buds in Tayefi Gulabi Varieties of Grapes

be left on each grape cape is important in pruning the grape trees. Environmental factors, grape varieties with the relevant coordinates, age, the number of trees per hectare, earlier pruning system, and plant breeding methods determine the necessary number of buds after pruning. The highest yield was obtained from Perlette grape varieties with six buds per branch [2]. For this purpose, cane pruning is recommended for this variety. Grape is a shrub, which produces fruiting buds (producer of grape clusters). The buds would be more fruitful in most grape varieties when perennial branches are located on biennial branches.In another study, the effects of various levels of pruning on growth, quantity and quality of grapes were investigated in Perlette grape varieties. The results showed that perennial 36 branches with two-buds pruning compared to perennial 24 branches with three-buds pruning and perennial 18 branches with four-buds pruning had the greatest effect on increasing soluble solids, reducing sugars, reducing acidity and decreasing Shot berrys [3]. Another experiment was conducted on ruby grape in dry land condition. The results showed that quantity of product is affected by the number of perennial branches and the number of flowering buds on the branches. Presence of 28 buds on each plant is sufficient in dry land conditions (Tafazoli, et al., 1996). In another study, the effect of 14 and 44 branches with respectively 1 and 2 clusters were examined in each branch. The results showed that increased product reduces fruit quality and the number of branches per plant has greater impact on fruit water quality than the number of clusters per shoot [4]. Yield in perennial branch is determined by the number of nodes per branch. Yield in each branch is determined by the number of clusters and fruit set [5]. In another study, the relationship between the number of clusters and vegetative characteristics was investigated
