Abstract
Abstract Barley, wheat, and rice have widely differing abilities to tolerate saline conditions. In a study of the amounts of Na .and Ca accumulated by seedlings under progressively increasing saline conditions, seeds were allowed to germinate in glass dishes on filter paper saturated with distilled water. Eight days after germination started saline solutions having osmotic concentrations of 0, 2, 4, 6, 8, 10, and 12 atm were added to each germination flask. After 24 hours of the saline treatments, seedlings were washed with distilled water and dried in oven. Sodium and calcium contents of shoots and roots were then determined by flame photometer. During the period of investigation rice accumulated more Na and Ca in both shoots and roots than either barley or wheat. Wheat accumulated more Na and less Ca in shoots than barley whereas the roots have less Na and more Ca than barley. Rice roots were less selective between both cations than those of barley and wheat.
