Abstract

Abstract

The research mainly studied whether the use of different concentrations of nano-titanium dioxide (TiO₂-NPs) (0, 25, 50, 100 and 200 mg/L) in hydroponic environment could alleviate the physiological toxicity of Cd to wheat seedlings. The oxidative stress on wheat caused by Cd was alleviated by TiO₂-NPs application in the hydroponic environment. The toxicity of Cd to wheat seedlings was alleviated, the biomass, root length and plant height of wheat were significantly increased, and the photosynthesis of wheat was improved. The net photosynthetic rate of wheat seedlings was increased significantly at medium concentrations (50, 100 mg/L) of TiO₂-NPs. For all concentrations of TiO₂-NPs, the POD enzyme activity was significantly lower than the Cd treatment group; the SOD enzyme activity was significantly lower than Cd treatment group at lower concentrations (<200 mg/L). Results showed that the use of TiO₂-NPs effectively alleviated the toxicity of Cd to wheat seedlings and improved the photosynthesis of wheat seedlings by reducing the oxidative stress caused by Cd.
