To explore the effects of citric acid concentration on the remediation of uranium contaminated soil by Lolium perenne and it's physiological characteristics,pot experiments were conducted to investigate the effects of different citric acid concentrations (0,1,5,10 mmol/kg) on the growth, physiology and uranium accumulation and distribution of Lolium perenne under the environment of 15 mg/kg uranium stress. The results show that with the increase of citric acid concentrations, cell inclusion parameters including growth, photosynthetic pigments, ...
