Influence of salinity on alpha-amylase and acid protease and the biochemical changes induced were investigated in two varieties of sorghum, differing in their salt tolerance during germination. Increase in the salt concentration of the external medium, resulted in the decrease of alpha-amylase and acid protease in both the varieties i.e., T. 8B (tolerant) and M.P. Chari (susceptible). The decrease was comparatively more in the susceptible variety, resulting in delayed mobilization of food reserves. The salt tolerance of variety T. 8B is attributed to its better malting capacity during germination.
