The effects of sodium and magnesium chlorides and sulphates on carbohydrate metabolism of corn seedlings and their component parts were studied. There was a decrease in the total carbohydrate content of seedlings with advance of time, in control and in different concentrations of salts. The decrease became less marked with increase of salt concentrations. The main effect of salinization, on the changes in carbohydrates, was strongest on the roots and grains. The roots contained the lowest proportion of the various carbohydrate fractions. This feature suggests that the mobilization of carbohydrates from grains to roots is greatly retarded by salinization. Both cations and anions exert an influence on the conversion of reserve carbohydrates
