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.
