Abstract

In order to evaluate the effect of DROUGHT stress on YIELD, YIELD components and ion contents of four WHEAT CULTIVARS (Roshan, Shiraz, Falat and Chamran) a split plot experiment was used in Research Station of Eghlid- Azad- University in which DROUGHT treatments [four water supply treatments (irrigating after the soil water potential reached -.0.5 bar (control), 1.5 bar, -3 and -5 bar were arranged as main plots and genotypes as subplots, based on a randomized complete block design with three replications. The measured parameters were YIELD and its components and leaves ion contents. The present study demonstrated that the number of spike and grain per plot were reduced significantly by stress. Grain weight was less sensitive to stress. Biological and grain YIELDs were decreased by stress. Among the cultivars Roshan had the lowest and Chamran the highest grain and biological YIELDs. Biological YIELD differences were related to lower plant height and tillers per plant and the grain YIELD differences were related to the reduction of ear per plant and grain per ear. Grain protein content was influenced by DROUGHT stress. DROUGHT stress caused decrease in ion contents except Na and Cl. In general the Roshan cultivar showed lowest YIELD, YIELD component and ion content while Chamran cultivar showed opposite results.
