Abstract

The effect of sodium chloride on the growth, phenolic, content and peroxidase activity of Tri ticum aestivum L. var. Chanab 70 was studied. High salt concentration retarded the root and shoot growth after 4 days of treatment, suppression of root growth was more than that of shoot presumably due to accumulation of ions. Decrease in peroxidase activity at -2 and -4 bar NaCl was coupled with the increase in total phenol level in the root tissues. Electrophoretic separation revealed that the peroxidases were markedly inhibited by increasing salt concentration after 2 days of treatment. Appearance of two new iso-enzymes after 4 days of treatment with -4 bar NaCl suggest
