Nutrient‐Nitrate Levels and the Accumulation of Chloride in Leaves of Snap Beans and Roots of Soybeans¹

Abstract

The concentration of chloride in leaves of ‘Encore’ snap beans ( Phaseolus vulgaris var. humilis ) and in roots of ‘S‐100’ soybeans ( Glycine max (L.) Merr.) varied inversely with nitrate concentration in the nutrient solution. Plants were grown in a greenhouse in perlite cultures automatically irrigated with complete nutrient solution. Although the concentrations of chloride and other anions were varied in some experiments, accumulated chloride was more closely related to nutrient nitrate than to nutrient chloride.
