Abstract

The MDA content in detached wheat leaves was decreased by Spm, in a dose dependent manner (Fig.1). The activities of SOD,CAT,POD and ASP in wheat seedlings were increased by Spm 0.2 mmol/L. The results of test in vivo and in vitro showed that exogenous Spm not only stimulated the enzyme synthesis of SOD and POD, but also promoted the activity of the existing enzyme (Figs.2,3); exogenous Spm stimulated the synthesis of CAT, but had no effect on the activity of the existing enzyme (Fig.4); exogenous Spm had no effect on the synthesis of ASP, but promoted the activity of the existing enzyme (Fig.5). It indicated that the ways through which Spm increases the activity of SOD, CAT, POD and ASP in wheat seedlings were different.
