Abstract
II is possible that side by side with a moderate secretion of phytosid erophore by maize, cyclic hydroxamic acids may also play a role in the Fe-uptake of the plant. The dynamics of the release of phytosideropho res of the mugienic acid type and that of cyclic hydroxamic acids are different: the secretion of the latter is enhanced not by a deficiency but by the presence of iron. Its daily pattern is also different, and its maximum is rather more characteristic of the dark period.
