| Abstract | ||||
| This study was carried out to investigate the effect of some agricultural treatments on bud fertility, vegetative growth and yield of Superior grape cultivar. Eight agricultural treatments were applied just before the beginning of bloom (before flower induction): removal of laterals. pinching the main shoots. girdling. removal of laterals + pinching the main shoots. removal of laterals + girdling. pinching the main shoots + girdling as well as removal of laterals + pinching the main shoots + girdling in addition to the control. The results showed that all conducted treatments. except removal of laterals were effective in increasing the percentage of fertile buds. number of buncheslvine. average bunch weight. yield. and improving physical and chemical characteristics of bunches and berries. dynamics of wood ripening. morphological and chemical characteristics of vegetative growth compared with control. pinching the main shoots + girdling followed by removal of laterals + pinching the main shoots + girdling resulted in a great stimulation on all the studied parameters. On the other hand. removal of laterals as well as control were found to record the minimum values of these characters. | ||||
