Abstract :
In this study the effect of alkalinity stress on physiological characteristics of plant Nitraria schoberi in 1391 under the terms of the greenhouse at the University of Kashan, were studied. Project consisting of 5 treatments (each treatment consisted of 4 replicates) and control, stress levels Four: The first level of control (pH = 7/2), Low alkalinity (pH = 8/5), Moderate alkalinity (pH = 9), High alkalinity (pH = 9/5) and extreme alkalinity (pH = 10) was conducted. Parameters of soluble sugars, Relative water content, Nitrogen and bicarbonate in different treatments Alkalinity (leaves, stems and roots) were examined. In order to analyze the data using Minitab software version 16 was used. Analysis of variance was performed using analysis of one way ANOVA. Compare averages with Tukey test at significance level was 5%. The mean comparison can be received by increasing the alkalinity of 8/5 treatments, Amount parameters of soluble sugars (leaves, stems and roots), Nitrogen (leaves, stems and roots), bicarbonate (leaves) and relative water content (leaves and stems) Increase and in third and fourth treatments reduced, While the bicarbonate (stems and roots), relative water content (root), fresh weight of the plant (stem) With increasing alkalinity Has increased first treatment and the trend of decline. In general it can be stated that the plant Nitraria schoberi in soils with alkalinity 9, and grows well in arid and semiarid areas of the plant can be be used to resuscitation vegetation cover.
