The Effects of IBA and H2O2 on Rooting of 2 Olive Cultivars

Abstract

Two groups of olive cultivars were characterized as showing low (Tokhmkabki) and high 
(Roghani) rooting percentage after application of IBA treatment. Semi-hard wood cuttings were dipped in 
H2O2 (0-3.5% w/v) and IBA (4000 mg.l-1) and also they were investigated in combination. H2O2 alone did 
not stimulate rooting of olive cuttings and there were no significant differences between this treatment and 
control in both cultivars. It was obvious that IBA treatments increased the rooting percentage, number of 
root cuttings, root length and root fresh\dry weight in 2 olive cultivars but the combination of IBA and H2O2
in some factors was more effective but there were no significant differences when IBA was used instead of 
in both cultivars
