Abstract
The research was carried out at privet nursery in Homs, study the effect of the type of cuttings (young, half-wooded and wooded), planting date (spring and autumn) and IBA concentrations (0,1000,2000,4000,6000 and 8000) mg.liter -1 on some rooting criteria of Pyracanth cuttings which were taken from two genotypes (red and orange),to determe the optimal treatment and the optimal date for vegetative propagation. The cuttings was implanted into containers containing perlite to monitor rooting, with three replications per treatment and each repeater contained eleven cutting. The studied characteristics were: Rooting ratio, rooting start date, average number of roots and rooting success rate. Variation analysis was performed and averages were compared using the value of the LSD at 0.05 using Genstat V12.0. The results showed the superiority of the half-wooded and wooded cutting over the young cutting in rooting ratio and superiority concentration of IBA 2000 mg.liter -1 on the other of the concentrations relative to the studied standards for those two genotypes of cutting. The rooting ratio reached 100% at this concentration of IBA for half-wooded and wooded cutting in both genotypes and planting dates. While the concentration exceeded 4000 mg.liter -1 on the rest of the concentrations for the young cutting for most of the studied standards was the highest rooting rate for the young cutting was 87.9% and was taken from the orange model in the spring. No significant differences were observed between the studied treatments for the mean number of roots in addition, there were no significant differences between the red and orange genotypes in the most of the studied treatments.
