Abstract: 

In order to evaluate the tolerance level and identification of tolerance mechanism to salinity, response of five genotypes of wheat (Zagros, Tajan, Opata/Bow, Pgo/Seri  and Rayon) to six salt treatments including 0, 25, 50, 75, 100 and 150 mM NaCl was studied in hydroponic culture in growth chamber under control condition. Pgo/Seri and Opata/Bow in comparison to the other genotypes, showed less reduction in growth under salinity. Pgo/Seri inhibited high Na+ accumulation in shoots and absorbed less Cl-. Opata/Bow accumulated high Na+ and Cl- in shoots and roots which probably were compartmented these toxic ions in the vacuole or apoplast to result a better osmotic adjustment and less toxicity of the ions. Tajan, Zagros and Rayon also accumulated high level of Na+ and Cl- that increased toxic effect of the ions. Results also indicated that Opata/Bow, in spite of high Na+ and Cl- accumulation, had higher salt tolerance in comparison to the other genotypes. Further field experiments are necessary for confirmation and application of the result.
