  1. The plant ability to accumulate Fe was evaluated by 59Fe uptake experiments on Fe-sufficient (+Fe) and Fe-deficient (−Fe) plants treated for 1 and 24 h with three labelled 59Fe-sources: (59Fe)Ferrihydrite, 59Fe-Citrate or 59Fe-PS. Data are means ± SD of three independent experiments. Small letters, refer to statistically significant differences among Fe-sufficient plants; capital letters, refer to statistically significant differences among Fe-deficient plants, asterisks, refer to statistically significant differences between the two growth condition (−Fe vs + Fe).
