Abstract
Series of pot experiments were conducted to study effects of lead stress on the physiological characteristics of potted Brassica chinensis. The results showed that the synthesis of chlorophyll and soluble protein were first not affected markedly and then inhibited significantly,the content of MDA decreased first and then increased with the increasing of Pb concentration. But POD activities were decreasing with the increasing of Pb concentration. The physiological indices indicated that the critical concentration of Pb in soil was about 600 mg·kg-1,and Brassica chinensis could maintain normal growth and the metabolic process proceeded smoothly at this concentration.
