- A pot experiment was carried out to investigate the effects of applying uniconazole on growth and cadmium (Cd) accumulation of accumulator plant Stellaria media. The results showed that application of uniconazole inhibited the growth of S. media, and promoted the absorption and transport of Cd from soil. The biomass and soluble sugar content of S. media decreased with the increase of the concentration of uniconazole, whereas the activities of SOD, POD and CAT, the contents of photosynthetic pigments and soluble protein improved. With the increase of concentration of uniconazole, the Cd content and Cd accumulation in the shoots of S. media increased first and then decreased, and reached the maximum up to 67.24 mg/kg and 190.42 g/plant respectively when the dose of uniconazole was 40 mg/L, which increased by 39.10% and 10.47% compared with the control, respectively. Therefore, application of uniconazole could enhance phytoremediation ability of S. media at the dose of 20-40 mg/L.
