A 0.5% solution of potassium naphthenates (KNap) was applied to the foliage of hydroponically grown 14‐ day‐old bush bean ( Phaseolus vuigaris L., cultivar ‘Top Crop’) plants to determine the effect of this chemical mixture on the uptake and distribution of root‐fed 32 P among leaf blade, stem, and root tissues. The plants were grown in eiither a phosphate‐free (−P plants) or a complete nutrient solution. The uptake of 32 P was not changed by KNap treatment. The percentage distribution of 32 P among the various plant organs, however, was markedly affected by the presence or absence of phosphate in the nutrient solution and by treatment. The enhanced translocation of 32 P observed, especially in −P plants, may be associated in a casual way with the characteristic stimulation of metabolic processes in the aerial portions of naphthenate‐treated plants.
