Effects of exogeneously supplied substances on the reduction of Na^+ transport to shoots from roots of rice (Oryza sativa L.) plants under 100 mM NaCl salinity were examined. Polyethylene glycols (PEGs) and Ca^<2+> 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 pathway to the Na^+ delivery to shoots under salinity stress in rice plants.
