The effect of different mediums and cuttings on growth and rooting of pomegranate cuttings

In order to evaluate the effects of kind of medium and kind of pomegranate cuttings (Malas- Torshe Savah) on rooting ability and growth of cuttings an experiment was done in a green house in research field of Islamic Azad University, Saveh on 2010. Main plots consisted of two medium cultures, (sand + peat and sand) and subplots consisted of three kinds of pomegranate cuttings (one bud, three buds, more than three buds). Cuttings were dipped in NAA solution with 4000 ppm concentration for 5 seconds and planted in different medium, bottom heat system (electric oven) were used to maintain temperature between 23-27 °C in the bottom of pots. The cuttings were harvested after 3 months and relevant data were recorded. The results showed that the effect of medium culture on length of roots, number of leaves and number of branches were significant (P > 0.05). Interaction of medium culture and kind of cuttings was only significant for root length. Comparison of rooting meanings showed that the effect of medium culture was not significant on any of the parameters. Comparison of means showed that the effects of kinds of cutting were significant on all studied parameters (P < 0.05). Cuttings with more than three buds had highest number of leaves, numbers of branches and number of buds, but the highest lengths of roots were observed on cuttings with three buds. Comparison of means also showed that the interaction of medium culture and kind of cuttings had significant effect on number of leaves, number of branches, and number of buds. Medium of sand × more than three buds of cuttings had the highest rooting potential; however, highest length of roots were observed on sand + peat medium × three bud cuttings.
