[Effects of chelating agents on toxicity of copper to Elsholtzia splendens].
Effects of chelating agents on toxicity of copper to and bioaccumulation in Elsholtzia splendens were investigated. EDTA (ethylenediaminetetraacetic acid) and DTPA (diethylenetriaminepentaacetic acid) inhibited plant growth, decreased the biomass, chlorophyll content and root activity. EDTA had very low or no influence on the toxicity of copper to Elsholtzia splendens. DTPA decreased copper-induced toxicity. DTPA decreased copper accumulation in Elsholtzia splendens. EDTA increased copper transfer from the subterranean part to the aerial part of the plant.
