Rooting of Some Fruit Clone Rootstocks of Prunus Species (Peach, Plum and Cherry) with Harwood Cuttings

Abstract

In this study, the effect of 0, 1000, 2000 and 4000 ppm doses of IBA on the rooting of hardwood cuttings of fruit clone rootstocks of Prunus species including peach (GF-677, Garnem), plum (Marianna GF 8-1, St. Julien) and cherry (SL-64) were investigated. The characteristics, such as live cutting ratio (%), callus formation rate (%), rooting ratio (%), the mean number of roots (piece) and mean root length (mm) of treated hardwood cuttings in were determined. The study was conducted with four-replication in the application greenhouse of Ahi Evran University, Faculty of Agriculture, Department of Horticulture, from December 15th of 2015 to March 15th of 2016. The study results indicated that all doses of IBA sustained better results in terms of the investigated characteristics comparing to the control application. The highest rooting ratio of 38% was obtained from 2000 ppm IBA application, while the lowest rooting ratio of 19% was obtained from the control application. The most appropriate dose of IBA for hardwood cuttings of the rootstocks was determined as 2000 ppm.
