The effects of EDTA on the mechanism of accumulation under Pb²⁺ stress in Typha orientalis Presl were investigated. The results indicated that addition of the chelator with Pb limited metal phytotoxicity. The mean total chlorophyll concentration and protein content were increased with the addition of EDTA in Pb²⁺ solution. We also demonstrated a significant effect of EDTA on the reduced glutathione (GSH) content which was obviously increased both in leaves and caudices. It was supposed that EDTA elevated the tolerance of Typha orientalis Presl under Pb²⁺ stress primarily by increasing the GSH level.
