Exogenous Application Of Ethylenediamminetetraacetic Acid Enhanced Phytoremediation Of Cadmium By Brassica Napus L., M Farid, S Ali, W Ishaque, M Shakoor, Nabeel Niazi, I Bibi, M Dawood, R Gill, F Abbas

Dr Nabeel Khan Niazi

Performance of B. napus in phytoextraction—an in situ environment friendly technique for the cleanup of contaminated soils—was evaluated through its response to cadmium (Cd) toxicity in combination with a chelator ethylenediamminetetraacetic acid (EDTA) while growing hydroponically in greenhouse conditions under three levels of Cd (0, 10, and 50 µM) and two levels of EDTA (0 and 2.5 mM). Cadmium presence decreased plant growth, biomass and chlorophyll concentrations, while the application of EDTA enhanced plant growth by reducing Cd-induced effects in Cd-stressed plants. Addition of EDTA improved the net photosynthetic and gas exchange capacity of plants under Cd stress. Presence of …
