Effect of Plant growth regulators on rooting of Kiwifruit (Actinidia deliciosa) cuttings

Abstract

An investigation was carried out at Experimental Farm of Sher-e-Kashmir University of Agricultural Sciences & Technology of Kashmir, Srinagar, India to find out the effect of IBA levels with Paclobutrazol on the rooting response of semi-hardwood cuttings of kiwifruit under zero energy polyhouse. The experiment comprised of four treatments viz. IBA 1500 ppm plus Paclobutrazol 500 ppm, IBA 2500 ppm plus Paclobutrazol 500 ppm, IBA 3500 ppm plus Paclobutrazol 500 ppm and control (Distilled water). These treatments were given on 4th March, 2015 and planted on the same day. The experiment was laid out in Completely Randomized Design with three replications per treatment. The results obtained from investigations revealed that the treatment of IBA at 3500 ppm plus Paclobutrazol 500 ppm provided best results of rooting response viz. rooting percentage (63.33%), number of primary roots, number of secondary roots, average root length, length of longest root, diameter of longest root, root mass and survivability of rooted cutting percentage.
