In this study, 17 kinds of vegetables were selected to make a contrast test ina nutrient solution cultured under the condition of 50 mg/L Ce pollution. Lactuca Sativa L., a low enrichment and normal growth, was selected by soil experiment to analyze the accumulation of Ce and its physiological and biochemical effects.The results of the experiments are showed as follows: (1) 17 kinds of vegetables grew in good condition under the same cerium concentration hydroponics.Theresults showed that the content of Ce was the highest in the edible part of Brassica Juncea, up to 98.21 mg/kg, while cerium accumulation in the edible part of Lactuca Sativa L. was the lowest, only 6.64 mg/kg. From the results we can identify that Lactuca Sativa L. belonged to the low accumulative vegetable.(2) Total and available cerium in rhizosphere soil of Lactuca Sativa L. showed a highly significant positive correlation (P<0.01), and cerium accumulation in edible parts of vegetables is significantly positive correlated (P<0.05) with the cerium content in soil. (3) With the increase of cerium content in soil, Lactuca sativa L. as low-accumulation vegetable varieties, its'antioxidant enzymes (SOD, POD, CAT) activity, proline content in plants increased at first and then decreased, and the content of MDA manifests a rising trend in general. This research has significant meaning for ensuring vegetable food safetyin polluted areas dealing with especially in rare earth mining areas.
