Abstract
Abstract Effects of exogeneously supplied substances on the reduction of Na+ transport to shoots from roots of rice (Oryza sativa L) plants under 100 mgt NaCl salinity were examined. Polyethylene glycols (PEGS) and Ca2+ were found to reduce significantly the Na+ transport to shoots without affecting the transpiration. The effect of PEGs was reproduced in soil culture. Maintaining the pH of the rooting solutions neutral also reduced Na+ transport to the shoots. These experiments indicated the important contribution of an apoplastic at way to the Na+ delivery to shoots under salinity stress in rice plants.
