Abstract

The present study was undertaken to study the effect of exogenously applied six hydrogen peroxide H2O2 concentrations (0, 20, 40, 60, 80 and 100 µM) as seed primer on two wheat varieties (Khirman and Inqalab) under salt and non-salt water levels (0 and 100 mM NaCl). The oxidizing effects were measured and estimated using the wheat index of different salt and non-salt water levels, as well as H2O2 soaking seed at varying fixations and concentrations. The H2O2 as a seed primer impacted on growth, yield and physiological and biochemical aspects such as moisture content, sodium potassium substance and sodium potassium content under H2O2 and NaCl levels. The results revealed that the exogenous application of hydrogen peroxide was effective in increasing tolerance of wheat under salt stress. The Khirman and Inqalab varieties could be established and cultivated under saline conditions. 60?M treatment of H2O2 is seen with the strongest impacts. Progress has contributed to enhance physiological and biochemical features of stress outflow, which promote growth.
