Copper Uptake and Translocation of Terminalia catappa Linnaeus (Talisay) in EDTA Amended Soil

This study evaluated the phytoextraction capability of T. catappa in soils that are artificially contaminated with 250, 1250, and 2500 mg?kg-1 of copper. Also, this study assessedthe accumulation and the translocation of copper byT. catappaif chelating agent EDTA is added. Results of the studyshowed a significant increase of copper accumulation with the addition of EDTA at 250 and 1250 mg?kg-1 of copper contaminated soils (p < 0.05). Whilst translocation of copper was observed in all treatments, translocation of copper is not significantly enhanced by the addition of EDTA (p > 0.05). This mechanism is not positively affected with the presence of EDTA. Furthermore,this study suggests that the T. catappa is not a hyperaccumulator of copper, and there is no relationship observed between the length of the plant and the copper uptake in all treatments.
