SALT STRESS TOLERANCE AND STRESS PROTEINS IN WHEAT

Abstract

One of the unique properties of living organisms is growth. Growth is a complex phenomenon and represents the end result of metabolic pathways bringing about an overall irreversible change. Growth is the final morphological expression of various metabolic activities taking place in the plant. Salt stress influences all these metabolic activities and hence influences growth also. Salt stress is caused by concentrations greater than the required for optimum growth of a typical crop plant. If excessive amounts of salt enter into the plant, salt will eventually rise to toxic levels and reduce the photosynthetic leaf area of the plant that cannot sustain growth. Because of the importance of wheat in Indian Agricultural Economy and in order to understand the processes that give rise to tolerance of salt and to identify the salt stress proteins into salt stress effect on plant growth was studied using different salt solutions like copper sulphate, cadmium chloride and zinc sulphate with different concentrations like 200µM, 150 µM and100 µM
