ACCUMULATION OF POTASSIUM, CESIUM$sup 137$, AND RUBIDIUM$sup 86$ IN BEAN PLANTS GROWN IN NUTRIENT SOLUTIONS
Journal Article

· Plant Physiology (U.S.)
By the addition of potassium to the nutrient substrate, Cs/sup 137/ and Rb/sup 68/ uptake by bean plants was reduced less than expected from an assumed physiological equivalence of those ions. Plants discriminated against cesium at low potasium nutrient concentrations; but with increasing substrate potassium. this discrimination diminished. Discrimination of Rb/sup 68/ from potassium approximated that observed for Cs/sup 137/. Potential errors from the use of ratios in predicting uptake of Cs/sup 137/ were discussed. Some toxicity was noted when significant quantities of nonradioactive cesium were in the nutrient solution. (auth)
