| Abstract: | In this research,we analyzed the contents and activity of antioxidant enzymes of Poacynum hendersonii under different salt sinkness stress.Seed germination of Poacynum hendersonii adopt salt solution by cultural way,0,0.05,0.1,0.2,0.3,0.4,0.5,0.6mol/L salt solutions were set to analyze the varied trends of MDA,SOD and Pro.The results showed with the salt thickness rising,the trends of contents of MDA and SOD activity are similar roughly,it presents the tendency of raise firstly and then decrease,there is ma... |
