Abstract
JACOBSON1 was the first to show that plants could utilize iron supplied as the ferric chelate of ethylenediamine tetraacetic acid (Fe–EDTA). Subsequent workers2,3 have concluded from experiments with isotopically labelled chelating agents that the iron was released after the uptake of the entire molecule by plant roots. Tiffin and Brown4, however, showed that, at least initially, iron was absorbed by roots from a phenolic analogue of Fe–EDTA while most of the chelating agents remained in the culture solution. The absorption of Fe–EDTA was therefore further examined, using the iron chelate labelled in both portions of its molecule.
