Response of Rooting and Some Biochemical Traits of Cutting of Olive (Olea europaea L.) cv. Concervolia to Indole Butyric Acid and Puterscine

This experiment was conducted to investigate the effect of different concentrations of indole butric acid (IBA) (0, 2000 and 4000 ppm) and puterscine (0, 100 and 200 ppm) on some of the morphological and biochemical traits of hard- rooting cutting of olive cv. Concervolia. Experimental treatments were arranged as factorial in randomized complete block design with three replications. Analysis of variance showed that IBA × puterscine effect was significant on rooting and callusing percentage, root number, root weight, shoot number and shoot weight as well as on carbohydrates and nitrogen content, C:N ratio, peroxidase and polyphenol oxidizes. The highest peroxides (0.114 µmol min-1 gFW-1), polyphenol oxidase (0.140 µmol min-1 gFW-1) and rooting percent (100%) were obtained in cuttings treated with 4000 ppm IBA, while rooting was 80 percentage in cutting treated with 4000 ppm IBA+100 ppm puterscine. Based on the results of this research, it can be cancluded that the concentration of 4000 ppm of indole butyric acid or the combination of 4000 ppm of indole-butyric acid and 100 ppm puterscine can be used for enhancing rooting in the hard- rooting cuttings of olive cv. Concervolia.
