Salt stress impact was appraised on different antioxidative enzymes, MDA and H2O2 in ten spring wheat cultivars i.e., S-24, Lasani, Fsd-2008, Saher-2006, Inqlab-91, AARI-10, P.B-18, S.H-20, M.P-65, and G.A-20 when salinity applied at the seedling stage. The wheat cultivars were grown under saline (150 mM) and non-saline regimes (0 mM) in pots filled with sand. Diverse response in all wheat cultivars was observed in different studied attributes. Saline stress markedly decline SOD, CAT and POD conc. in different wheat cultivars. While some cultivars (S-24, Lasani, AARI-10 and GA-20) showed increase in these attributes under saline condition as compared to control. MDA and H2O2 content were increased in different wheat cultivars due to imposition of salt stress at the seedling stage. Whereas decrease in some cultivars was recorded in these attributes under saline regime than in non-saline conditions. Of all wheat cultivars, S-24, Lasani, AARI-10 and GA-20 showed high antioxidative activity, less lipid peroxidation and H2O2 content in plant shoot when salt stress applied at the seedling stage. On the basis of higher antioxidative activity and less MDA and H2O2 content, these four cultivars (S-24, Lasani, AARI-10 and GA-20) could be categorized as salt tolerant as compared to others.
