Abstract   In Greece, GF677 (peach x almond hybrid) peach rootstock is widely used where replant diseases are a problem. In this study, the influence of orientation, rooting substrate, wounding, and jar environment on the rooting success of GF677 hardwood cuttings was examined. The best rooting was achieved by vertical positioning of the cuttings and the lowest by oblique and horizontal positions. The cutting lengths of 20 and 30 cm were better than 10 cm. Perlite was the best substrate for rooting, whereas cuttings in peat gave no rooting. “Double-split” wounding of cuttings increased the rooting percentage by over 29% compared with a non-wounded control. Rooting of wounded and non-wounded cuttings was achieved only in damp perlite (20% moisture) and loosely closed jars. No rooting or callusing was observed in cuttings held in the tightly closed jars.
