In order to make peach meadow orchard systems feasible, the possibility of propagating peaches by hardwood cuttings and thus reducing the establishment cost of this extremely high-density planting system was examined. A medium temperature of 25°C was harmful to auxin-treated peach cuttings, but excellent rooting could be obtained at a temperature as low as 12°C. Further trials conducted under outdoor conditions in winter in the coastal plain of Israel, with a soil temperature of 12-14°C, did not show any effect of timing on rooting, providing the cutting was taken mature enough (after mid-November) and not later than about 6 weeks prior to bud break. In 30 days root initiation started. Although variations were found between cultivars, 1500 mg/l of indole butyric acid in a 5-second base-dip was found to act well with most cultivars. Good aeration was shown to be critical for good root formation. Leaving the cutting for 1 month in damp sand prior to planting in orchard soil was satisfactory. An area of a few hectares of commercial meadow orchards has already been established with this method. © 1981.
