Title

CHANGES IN SOME PHYSIOLOGICAL AND BIOCHEMICAL CHARACTERISTICS OF THE SELECTED OF ALMOND CULTIVARS (PRUNUS DULCIS MILL.) GRAFTED ON DIFFERENT ROOTSTOCKS UNDER DROUGHT STRESS

Pages

Abstract

 In order to evaluate the response of selected cultivars of almond, grafted on different ROOTSTOCKs under drought stress due to increased irrigation intervals in the 2015-2016 year, in the Temperate Fruit Research Center, Horticultural Research Institute in Karaj, a factorial based on a randomized complete design with three replications was carried out. Factors comprised cultivars in five levels (Supernova, Texas, Marcona, Shokoufeh and K13-40), ROOTSTOCKs in Three levels [peaches × almonds hybrids (GF-677 and GN-22), and bitter almond seedlings NO.32], and drought stress in four levels (irrigation intervals were 3 (Control), 5, 10 and 15 Days). The results showed that the interaction of three factors for CHLOROPHYLL fluorescence parameters include maximum (Fm), variable (Fv) and variable to maximum (Fv/Fm), ELECTROLYTE LEAKAGE and releate water content (RWC) of leaves at 1% probability level, and interaction effects of ROOTSTOCK × cultivar for CHLOROPHYLL b and a/b as well as cultivar × drought stress for a/b were significant at 5% probability level. Also, interaction effects of ROOTSTOCK × drought stress were significant for all evaluated traits except a/b at 1% probability level. Drought stress reduced Fv by increasing Fo and decreasing Fm, and reduced Fv/Fm in sensitive cultivars on seedling and GN-22 ROOTSTOCKs from 0.82 to 0.67. As a general result, all of the cultivars on the GF-677 ROOTSTOCK showed greater resistance to drought stress. Supernova and Shokofeh cultivars grafted on GF-677 ROOTSTOCK were most resistant ROOTSTOCK - SCION compounds, but other ROOTSTOCK-scions compounds, were sensitive to drought stress.
