Summary
Bush bean plants were exposed to either Rb86 or Cs137 with and without carrier rubidium or cesium for 48 hours in a complete nutrient solution. These solutions were then discarded. The plants were then allowed to grow for 11 additional days in complete nutrient solution except that potassium was omitted. Measurement of Rb86, Cs137, and potassium in new leaves indicated that Cs137 was retranslocated to the new growth much slower than was potassium but that proportionately more Rb86 was in new leaves than potassium and these results were independent of the presence or absence of the respective carriers. Considerably more Rb86 than Cs137 was absorbed by the plants either with or without the carriers.
