Abstract

Since the mass production of saplings was inevitable as a requirement for the establishment of nt::w olive orchards in the country, this experiment was conducted to find out the effect of mother plant leaf nutrition and cutting position on the rooting of semi-hard wood cuttings of olive, zard variety. This experiment was carried out during summer and autumn of 1996 in Roodbar
district and in research greenhouses of hort. Dept. Of tehran university. The mother plants were sprayed with different concentrations of complete nutrients, i. e. phosyn with 100, 44, and 70 gr./liter of N.P.K, plus Mg, Cu, B,
Zn and Mn, 45 days prior to cuttings preparation in 15 day intervals during sept. semi-hard wood cuttings were taken from basal, intermediate and upper
parts of their shoots. The results indicate that leaf nutrient spray with %3 concentration increases the: rooting percentage and roots elongation in
semi-hard wood cuttings. Besides the cuttings from the upper parts of the shoots produced the highest: number of roots,more root density as well as longer roots. This experiment was carried out using a completely randomized
block design with factorial treatment.
