| 英文摘要 | In this study,a polysaccharide from Enteromorpha prolifera(EP)was extracted and its effect on maize seedlings under NaCl stress was investigated.Firstly,the components and structure of the EP were determined.We found that EP is a sulfated polysaccharide of high-molecular weight(Mw,1 840 KDa)heteropoly saccharides and the main mono saccharide is rhamno se.The poly saccharide was applied to explore its effect on the growth of maize seedlings and its defense response under a salt stress.The results show that EP could promote the growth of maize seedlings under the salt stress.In addition,EP was shown able to significantly regulate membrane permeability and adjustment of osmotic substances such as soluble protein,soluble sugar,and proline,antioxidant enzymes containing superoxide dismutase,catalase,peroxidase,and ascorbate peroxidase.Therefore,EP is an effective salt-resistant substance for the growth of maize seedlings under NaCl stress. |
