The effects of water stress on soluble protein content,the activity of SOD,POD and CAT of two ecotypes of reeds (Phragmites communis)

WANG Jun-gang 1*,CHEN Guo-cang 2,ZHANG Cheng-lie 2 (1 Department of Resources and Environment,Zhejiang Forestry College,Lin'an,Zhejiang 311300,China;2 College of Life Science,Lanzhou University,Lanzhou 730000,China)  
Two ecotypes of reeds were used as experimental material and stressed under PEG6000.The results showed that the drought-resistant reed (dune reeds) contained less soluble proteins than that of the drought-sensitive reed (swamp reeds).However,the soluble protein content of dune reeds declined less than that of swamp reeds under water stress.Dune reeds exhibited higher activity of SOD,POD and CAT when compared with swamp reeds.When two ecotypes of reeds were stressed with PEG,the activity of SOD,POD and CAT increased while that of POD decreased continually.In general,there were higher activities of SOD,POD and CAT in dune reeds than in swamp reeds.Therefore,the results suggest that the drought resistance of plants is closely related to their activity of ROS scavengers.
