We grew bush bean plants in pots containing Yolo loam soil in a glasshouse for 15 days with a uniformly applied level of /sup 241/Am in soil and with various concentrations of DTPA applied to the soil. The objective was to demonstrate that the effects assigned to this chelating agent on uptake of /sup 241/Am by plants will vary with concentration of the chelating agent. On a concentration basis, the DTPA resulted in transport of much more /sup 241/Am into primary leaves than into trifoliate leaves. The ratio of /sup 241/Am in primary leaves to that in trifoliate leaves increased with increasing concentration of DTPA. The concentration ratios in each plant part also increased with increasing DTPA.
