Abstract

Abstract: Salinized soil is widely distributed in China, and waxy maize has a broad development prospect, so it is of great significance to study the effects of exogenous substances on the seedling physiological characteristics and growth of waxy maize under salt stress. The effects of different concentrations of zinc sulfate on physiological characteristics of waxy maize seedlings were studied under salt stress soil. The results showed that the contents of soluble sugar, soluble protein and proline in seedlings treated with 0.20 g/L zinc sulfate significantly increased compared with the control group under soil salt content of 3.80 g/kg, the activities of catalase, superoxide dismutase, peroxidase and α-amylase significantly increased compared with the control group, and the content of malondialdehyde significantly decreased compared with the control group. The salt stress of waxy maize seedlings could be alleviated by increasing the activity of antioxidant enzymes, increasing the content of osmotic substances and decreasing the content of malondialdehyde with 0.20 g/L zinc sulfate.

Key words: waxy corn, zinc sulfate, enzyme activity, osmotic material
