Effects of Lead Stress on Chlorophyll Content and the Activity of Antioxidant Enzymes in Waxy Corn Seedling Leaves

doi:10.7668/hbnxb.2010.S1.027

Abstract

Abstract: We studied the effects of lead stress on chlorophyll content and the activity of antioxidant enzymes in waxy corn seedling leaves. The experiment results showed that with the increase of lead concentration the contents of chlorophyll a,chlorophyll b,and total chlorophyll decreased in waxy corn leaves; and the activities of SOD,POD,CAT first increased then decreased; The treatment of low concentrtion lead stimulated the growth of waxy corn,however the treatment of high concentration lead hold it.

Key words: Waxy corn, Lead stress, Antioxidant enzyme
