Abstract

The effects of paclobutrazol (PP333) on cadmium (Cd) accumulation of Stellaria media were investigated through a pot experiment. The results showed that the root biomass increased with the increase of PP333 concentrations, but the shoot biomass and total biomass decreased. PP333 enhanced the photosynthetic pigment content, antioxidant enzyme activity and soluble protein content of S. media, and decreased the soluble sugar content in shoots of S. media. The low concentrations of PP333 (25 and 50 mg/L) increased the Cd content in roots of S. media, and high concentrations of PP333 (100 and 200 mg/L) decreased that. The Cd content in shoots increased when applied the treatments of PP333. When applied PP333 on S. media, the Cd accumulation amount of roots was higher than the control, and the Cd accumulation amount of shoots and whole plants were lower than the control. Therefore, PP333 could not improve the phytoremediation ability of S. media.
