Effect of Fe availability on Cu, Zn, Fe contents, Fe use efficiency for dry weight (FeUE), Fe efficiency based on root dry weight (FeE), Fe uptake efficiency (FeUp), Fe transport efficiency (FeT) and Fe acquisition efficiency (FeAE) in roots of three genotypes of <i>Medicago truncatula</i> grown in the presence of Fe (C), under Fe deficiency (DD) and induced Fe deficiency by bicarbonate (ID) during the treatment period (21 days).
