Summary To provide a better understanding of plant responses to salt and water stresses, the effects of high concentrations of sodium chloride (NaCl) and polyethylene glycol (PEG) on the growth and ion absorption in plants were examined at similar osmotic potential conditions, using the water culture method. The inhibitory effect on plant growth appeared to be only slightly larger in PEG treatment than in NaCl treatment. However, the depressive effects on K, Ca and Mg contents of plants were more severe with NaCl treatment than with PEG treatment. No depressive effects of NaCl or PEG were observed for P content. From the short term absorption experiment using a tracer technique, it was also evident that the inhibition of K absorption was more drastic in NaCl treatment than in PEG treatment. On the other hand, the inhibitory effects of high concentrations of NaCl and PEG were very small on P absorption.
