Abstract:  Among a biotic stresses, salinity is serious global threat to agriculture and adversely affects on environment. The research intentions identify affection of salt stress of several concentrations (0, 50, 100, 150 mM NaCl) on growing parameters and photosynthesis pigments of wheat under controlled environment. Plants were harvested for measurement of physiology parameters and seedlings were investigated as well. The results showed clear effect of salinity on physiological parameters especially at high salinity concentration (150 mM NaCl) with increasing plant age. By increasing the salinity parameters such as plant fresh weight, plant dry weight, (RGR), (NAR), (RLGR), (SLA) and chlorophylls content decreased. Also end result shows that wheat plant could endure 50 and 100 mM of salt solution. Wheat, showed sensitivity to 150 mM salt solution.
