Currently, the pollution of mercury in soil in China is getting worse. It's extremely urgent to search for the landscape plants with some resistance to mercury stress. This research took the two warm-season turf grasses Carpet grass and Centipede grass as materials, studied the effects of Hg2+on physiological and biochemical characteristics of them by using the method of pot simulation. The results showed that with the increase of the concentrations of Hg2+and the processing time of stress, the content of M...
