Plant growth, metabolism and adaptation in relation to stress conditions. XIII comparative effects of salinity on the activity of certain enzymes in both french bean and maize plant

activity of certain enzymes in both french bean and maize plant Changes in the specific activity of 8 respiratory enzymes were measured in the extracts of seedlings, whole plants and of leaves during growth on Hoagland media supplemented or not with increaseing concertrations of Na2 SO4 The Different Enzymes Appeared to respond differently to salinity in seedlings, whole plants and leaves of both Phaseolus vulgaris and Zea mays. The present results may therefore be explained on the basis of differential effects of salinity on the different enzymes in the various tissues studied
