EFFECT OF CHELATING AGENTS ON THE UPTAKE OF Y$sup 91$, Rh$sup 106$, Ce$sup 144$, AND Pm$sup 147$ BY BEANS GROWN IN A CALCAREOUS SOIL
The influence of cyclohexane-1,2-diaminetetraacetic acid (CDTA), diethylenetriaminepentaacetic acid (DTPA), and ethylenediamine di(o- hydroxyphenylacetic acid) (EDDHA) on the uptake of Y/sup 91/, Ru/sup 106/, Ce/sup 144/, and Pm /sup 147/ by bean plants grown in a calcareous soil was studied. DTPA greatly increased the amount of Y/sup 91/, Ce/sup 144/, and Pm/sup 147/ accumulated in plant parts, especially the leaves. CDTA increased the Y/sup 91/ and Pm/sup 147/ uptake but the uptake of Ce/sup 144 was affected only slightiy. EDDHA slightly increased the Y/sup 91/ and Pm/sup 147/ accumulation in the leaves but did not affect that of Ce/sup 144/. In general, the three chelates did not significantly affect the uptake of Ru/sup 106/ by plants. Application of chelating agents to the soil did not significantly change the dry weight yield of the plants. Paper chromatography of leaf extract indicated that Y/sup 91/-DTPA complex was present in the leaves of bean plants grown in a soil treated with Y/sup 91/ and DTPA. This indicated that Y/sup 91/-DTPA complex may have been translocated from the roots to the leaves. (auth)
