摘要：

Seedlings of Sorghum bicolor (L.) Moench were subjected to 180 mM NaCl with or without 0.25 mM spermine (SPM) for 7 d. NaCl treatment resulted in the inhibition of growth and increased the content of free proline, soluble protein and malondialdehyde (MDA). Additionally, it also enhanced the activity of catalase (CAT), peroxidase (POX) in both shoots and roots, while decreased that of glutathione reductase (GR). When exogenous spermine was added to the test solution, the growth of sweet sorghum seedlings was improved, and a smaller increase in the free proline and MDA contents was observed. The addition of spermine also partially increased the activities of POX and GR, but had no effects on soluble protein content or the activity of CAT.
