Abstract

In this paper, using artificial controlled pot experiment to treat Sonchus arvensis L. with different concentrations of cadmium (Cd), the tolerance of Cd in S. arvensis was studied, and the results showed that with the increase of Cd concentration, biomass rises first and then falls, the chlorophyll showed a downward trend,SOD, POD and CAT three enzyme activities were increased first and then decreased. MDA has a certain increase. When the Cd concentration was 0.5mg/ kg, the biomass reached the maximum value, the increase was about 10.17% compared with the contrast group, and there was no significant difference in chlorophyll content compared with contrast in the low concentration Cd treatment (P<0.05). When the Cd concentration was 1.0mg/kg, SOD, POD and CAT showed higher activity. Compared with the control, SOD activity increased by 12.99%, POD activity increased by 80.39%, and MDA content did not increase, and significant reduced by 15.11%. It indicated that S. arvensis has strong tolerance to Cd pollution, and S. arvensis has certain potential application value in repairing Cd contaminated soil.
