Abstract
Wheat (Triticum aestivum L.) is one of the most important crop plants worldwide. It is the preferred cereal in most arid and semi-arid regions. Wheat genotypes exhibit different physiological responses to salt stress. Sakha 8 wheat variety as well as wheat-grasses Sorghum virgatum and Lolium perenne are salt-tolerant. S. virgatum is an annual desert grass, used extensively for its grains. Perennial ryegrass (L. perenne) is important in forage/ livestock systems. Salinization is a threat to global food security. The tolerance to high salinity as an abiotic stress is a quantitative trait. High salinity causes many problems in leaf and root growth. So we intended to compare the physiological and anatomical responses to salinity among the wheat variety sakha8 and the wheat-grasses Sorghum and Lolium.In the present study, salt stress caused a significant decrease in shoot, root growth parameters as well as seed germination percentage in sakha8, Sorghum and Lolium plants. In case of CMS, increasing in salinity stress showed increasing in cell membrane stability. From leaf and root anatomy of Sakha8, wheat plant treated with 0. 5% NaCl showed a decrease in leaf and root parameters were detected. Generally sakha8 wheat variety could afford salinity better than Sorghum and Lolium plants. Finally, further biochemical and molecular analysis are needed in this comparison to obtain wheat plants more salt tolerant.
