| 摘 要： | Objective] The experiment aimed to study the effects of cadmium pollution in soil on physiological and biochemical index of Allium sativum L. and provided reference for the recovery of cadmium pollution in soil. Method]By setting eleven Cd concentrations from 0.21 to 500 mg/kg in soil and the pot test, ecological corresponding mechanism of plant height, chlorophyll (Chl) content, catalase (CAT) activity and malondialdehyde (MDA) of Allium sativum L. was analyzed. Result] The plant height had a strong tolerance to cadmium pollution in soil, while the total chlorophyll content and chlorophyll a content had no significant difference compared with control treatment, except Cd concentration was 500 mg/kg. The high Cd concentration would increase the damage to membrane of Allium sativum L. however with the regulation of physiological mechanism, the damage was gradually decreased.Conclusion] Allium sativum L. had strong eco-physiological adaptability to Cd contaminated soil and it had potential for recovering Cd contaminated soil.
