Abstract:

Biodegradable chelating ligands Ethylenediaminedisuccinic acid (EDDS), Hydroxyimi-nodisuccinic acid (HIDS) and Methylglycindiacetic Acid (MGDA) for iron (Fe) and arsenic (As) bioavailability and uptake were investigated using hydroponic rice (Oryza sativa L.). The growth of rice seedlings decreased significantly (P < 0.05) with increasing pH. The highest growth was observed at pH 7 which was related to Fe concentrations in roots and shoots. As and Fe uptake in rice roots was increased by significantly (P < 0.05) by EDDS and HIDS, while their translocation to shoots were not influenced by the ligands. EDDS and HIDS were more efficient in As and Fe uptake than MGDA indicating that EDDS and HIDS would be good ligands for the increase of Fe uptake and Fe phytoextraction. © 2012 Taylor & Francis Group.
