dc.descriptionThe rootstock GF677 is an interspecific hybrid with an important economic and horticultural value. In this research, the effect of indole butyric acid (IBA) in combination with putrescine (Put) and hydrogen peroxide (H2O2) on rooting of GF677 semi-hardwood stem cuttings in three cutting seasons (July, March and October) was investigated. Treatments as IBA (0, 1000, 2000 and 3000 mg L-1), Put (0, 800, 1600 and 3200 mg L-1) and H2O2 (1.5, 3 and 6% w/v) were included. The results showed that in July cuttings, the highest levels of callogenesis were observed in IBA treated cuttings in both concentrations of 1000 and 2000 mg L-1. The rooting was very low in July cuttings, while the highest percentage of rooting (14%) was observed in the combination of 2000 mg L-1 IBA+ 3% H2O2. In March, the cuttings treated by 1000 mg L-1 IBA+800 mg L-1 Put and 1000 mg L-1 IBA+1600 mg L-1 Put revealed the highest percentages of callus formation 83.31 and 83.33%, respectively. In these cuttings, the highest percentage of rooting (63.88%) was gained at 2000 mg L-1 IBA+3200 mg L-1 Put. The application of 1000 mg L-1 IBA+800 mg L-1 Put increased root fresh weight. In cuttings prepared in October, only 800 mg L-1 Put caused callus formation in more than 55% of the cuttings. The rooting of cuttings at this time was as low as the July cuttings, whereas the highest rooting percentage was observed in cuttings treated with IBA at a concentration of 1000 mg L-1. Overall, the experiment showed that the season of the cutting and the treatments with IBA+Put or H2O2 could improve rooting properties of the rootstock GF677.
