Abstract
This research was conducted to evaluate the effect of gibberellic acid (GA3) (0.250, 500 and750 mg L-1) on vegetative growth of olive sapling (Olea europaea L) in 2004-05 at Shahid Chamran University of Ahvaz. The experiment was a completely randomize design with 4 replications. Parameters measured were: shoot height, inter-node length, leaf and root area, fresh and dry weight of shoot, root and leaf. The results showed that GA3 significantly increased root length (157 cm), fresh and dry weight of leaf (15.30 and 6.61g respectively), fresh and dry weight of shoot (31.62 and 17.85 g respectively) and fresh and dry weight of root (15.04 and 6.34 g respectively) compared to control. The highest concentration of GA3 had the highest effect on vegetative growth.
