Plant Response to Saline Substrates V. Chloride Regulation in the Individual Organs of Hordeum Vulgare During Treatment with Sodium Chloride

Abstract

This paper describes the effects of sodium chloride on H. vulgare during the whole of plant development. Rapid increases in sodium and chloride concentrations occurred during the early tillering, with little further change until grain formation. The net chloride and sodium intake did not change markedly during the major part of plant development, so that increases in sodium and chloride concentrations were prevented by the regulatory effect of rapid growth. During senescence the relative growth rate decreased and there were marked increases in chloride and sodium concentrations.
