摘要

Among the abiotic stresses, salinity is one of the most destructive factors which limit crop production considerably. Greenhouse experiments were conducted in the National Research Centre, Dokki, Giza, Egypt during two successive winter seasons 2011/2012 and 2012/2013 to study the differential responses of two wheat (Triticum aestivum L.) cultivars to salinity stress (0, 3000 and 6000 mg/l) and foliar treatment with 0, 200, 400 and 600 mg/l ascobin (compound composed of ascorbic acid and citric acid) were studied. Irrigation with different salinity levels caused significant reduction in most of growth parameters (plant height, number leaves/plant, leaf area/plant, circumference of main stem, fresh and dry weight of shoot and roots) and some physiological parameters (IAA, GA cytokinins, photosynthetic pigments, polysaccharides 3, and total carbohydrate contents). The reduction effect on Giza 168 cultivar was higher than Sids 1 cultivar at different salinity levels. Meanwhile TSS% content was increased under salt stress conditions. The increase was higher in Giza 168 than Sids 1. Salinity stress with different levels caused higher reduction in yield and yield components (plant height, spike length, number of spikes/plant, number spikelets/spike, spike weight, grain weight/plant and 1000 grains weight) and nutritional value of the yielded grains (total carbohydrates and total protein) of Giza 168 than of Sids 1 cultivar. Application of ascobin with different concentrations not only mitigated the inhibitory effect of salt stress in both wheat cultivars, but also in some cases induced a stimulatory effect greater than that estimated in the control plants on growth parameters which were accompanied by marked increases in IAA, GA3, cytokinins, photosynthetic pigments, total carbohydrates and polysaccharides contents. While, decreases in ABA as compared with those of the reference controls. On the other hand, yield and yield components showed progressive increases with increasing ascobin treatments. Also the nutritional values of the yielded grains were also increased in response to ascobin treatment in both cultivars.
