The experiment aimed at assessing the effects of the progressive salinity stress, as well as investigating the physiological behavior viz., soluble protein content, NRase enzyme activity, proline and catalase enzyme activity in green gram subjected to sodium chloride during the seed germination under laboratory conditions in the Vanavarayar Institute of Agriculture (TNAU affiliated), Pollachi, Tamil Nadu, INDIA. The parameters that were measured are the total soluble proteins, NRase enzyme activity, proline and catalase enzyme activity. The experimental design carried out was CRD, with eleven treatments and two cultivars of CO6 and CO8. There was decrease in the leaf relative water content and soluble protein content in plants under salinity, however NRase enzyme activity were increased by 32 per cent respectively. Indicating that the carbon metabolism is quickly modified and utilized as reserve source and membrane protector during the salinity stress. Besides this, there was an increase in proline and catalase enzyme activity was noticed to the salinity stress.
