Abstract

The effects of diethylene triamine pentaacetic acid (DTPA) on cadmium (Cd) accumulation of hyperaccumulator Galinsoga parviflora were investigated through pot experiment. The results showed that the biomass, chlorophyll content of G. parviflora decreased with the increase of DTPA concentrations in the soil. Applying DTPA increased Cd content in G. parviflora, and the maxima of Cd content in shoots of G. parviflora were the dose of 4 mmol/kg DTPA, which increased by 347.39% compared with the control. Applying DTPA also increased Cd extraction by G. parviflora, and the dose of 4 mmol/kg DTPA was the best concentration in this experiment to improve Cd extraction by G. parviflora. Therefore, DTPA enhanced the Cd extraction ability of G. parviflora from Cd-contaminated soil, and 4 mmol/kg DTPA demonstrated to be the best dose that could be used to enhance the phytoremediation ability of G. parviflora efficiently.
