The result showed that cuttings treated with IBA at a concentration of (4000 mg.L-1) increased, significantly the rooting percentage, number and length of roots and dry weight of roots, shoots length, number leaves and dry weight of vegetative comparing with other concentrations.
The results showed also superiority variety Salimi significantly on the other varieties in the most vegetative characteristics and roots. the varieties different in their responsiveness of the IBA, where superiority cultivar Salimi and treatment concentration (4000 mg.L-1) significantly to give the highest rate of characteristics studied, followed by the product was Hloo.
