%X In this project, the effects of elements (Na+, K+ and ClĄ„) accumulations and proline contents on the salinity tolerance in seven genotypes of durum wheat (Triticum turgidum L. susp durum) were studied under greenhouse condition that has been collected from the region of Middle East. Seeds of durum wheat genotypes are including: ICDW19697 (Turkey-1), ICDW751 (Syria-1), ICDW859 (Iran-1), ICDW446 (Egypt), ICDW19697 (Syria-2), ICDW19764 (Turkey-2) and ICDW324 (Iran-2) that planted under hydroponics condition. Salt stress was initiated in three-leaf stage, by gradual adding NaCl to the nutrient solutions and applied salt treatments as 0 (control), 50, 100, 150, 200 and 300 mM NaCl. The results showed that all genotypes died in concentrations of 200 and 300 mM NaCl and also all genotypes showed decrease of growth in concentration of 150 mM NaCl respect to control (0 mM NaCl). In concentration of 150 mM NaCl, genotype of ICDW751 (Syria-1) has minimum accumulation Na+ (40 mg Na+ g-1 DW) and maximum accumulation K+ (50 mg K+ g-1 DW) and high proline content in shoot have been higher dry weight that itĄŻs known as salt tolerance respect to other genotypes and genotype of ICDW324 (Iran-2) with high accumulations of Na+ and ClĄ„ and also low accumulations of K+ and low proline content in shoot have been lower dry weight that itĄŻs known as salt sensitive respect to other genotypes. In concentration of 150 mM NaCl, genotype of ICDW19697 (Syria-2) has highest proline content at the shoot. In general, results from above measurements indicate that among genotype of Iran-2 has low resistant to salinity whereas genotype Syria-1 show better resistant to salinity than the others because it had minimum content of Na+ and had more K+, K+/Na+ ratio than the others genotypes in 150 mM NaCl in the medium.
