Fifteen grass species were grown in sand culture solution with varying concentrations of NaCl (Na: 0ppm, 100ppm, 1000ppm.) and compared the growth of plant tops and contents of their Na, K, Ca, and Mg. 1) There were observed marked specific differences in growth response to Na concentrations in culture solution. 2) The increase of Na concentrations in culture solution resulted in the increase of Na content and the decrease of K content in the plant tops of each species. However, the effect of increasing Na on Ca and Mg contents was not consistent among species. 3) Species were divided into three groups in relation to their Na, and K accumulation ratios (equivalent percentage of Na or K content to total cation content); 1 Species with low Na and high K ratios under the low Na medium, whereas high Na, low K ratios under the high Na medium, 2 Species with similar response to 1 under the low Na medium, but low Na, high K ratios under the high Na medium and 3 Species with high Na and low k ratios under the both low and high Na media.
