Rooting Response of Five Pomegranate Varieties to Indole Butyric Acid Concentration and Cuttings Age
Saed J. Owais

Abstract:
The purpose of this study was to evaluate the effect of cutting age and Indole Butyric Acid (IBA) treatments on five pomegranate varities propagation by stem cuttings. The experiment was carried out in a partially controlled glasshouse conditions at Mutah University, Jordan. The treatments comprised of two types of cuttings, i.e., hardwood and semi-hardwood; five concentrations of IBA, i.e., 3,000, 6,000, 9,000 and 12,000 ppm as quick dip (10 sec) as well as five Jordanian pomegranate varieties (Kdaree Hello, Hmadee Hmaree, Kdaree Sfaree, Zeklabi, Maleese). In this study, the percentage of cuttings that rooted, the number of roots produced per cutting, root length and diameter and root weight per cutting were recorded. It was obvious that the rootability of pomegranate is influenced by the interactive effect of cuttings age, IBA concentration and variety as well as by the single effect of either. The cuttings taken from hardwood stems had higher rooting percentage than those taken from semi-hardwood stems with a considerable differences in rootability between varieties under this study. The highest percentage of cuttings that rooted was observed in Hmadee Hmaree (70%), Zeklabee (69%) and Malesse (73%), while the lowest rooting percentage in Khdaree Hello (58%) and Kdaree Sfaree (49%) varieties. Zeklabee and Hmadee Hmaree varieties when compared with other varieties gave more favorable results at 6000 to 9000 ppm IBA in terms of the percentage of cuttings that rooted, the number of roots produced per cutting and root weight per cutting using both semi- and hard-wood cuttings. It was concluded that the increasing dose of IBA could be useful in increasing rooting potential and other root characteristics in pomegranate.
