Abstract
- The effects of uniconazole (S-3307) application on the growth and cadmium (Cd) accumulation of accumulator plantMalachium aquaticum(L.) Fries. were studied through a pot experiment. The application of S-3307 increased the biomass and photosynthetic pigment content ofM. aquaticumin Cd-contaminated soil, and also improved the superoxide dismutase (SOD) and peroxidase (POD) activities inM. aquaticum. Application of S-3307 increased Cd content in shoots and decreased Cd content in roots ofM. aquaticum, but the translocation factor (TF) ofM. aquaticumincreased with the increase of S-3307 concentration. For phytoextraction, the application of S-3307 increased Cd extractions by roots, shoots and whole plants ofM. aquaticum, and the maxima were obtained at 75 mg L−1S-3307, which increased by 22.07%, 37.79% and 29.07%, respectively, compared with their respective controls. Therefore, S-3307 can be used for enhancing the Cd extraction ability ofM. aquaticum, and 75 mg L−1S-3307 was the optimal dose. [ABSTRACT FROM AUTHOR]
