Abstract:
Taking Bidens alba L.,Dicranopteris dichotoma L. and Commelina communis L.as materials,effect of Wedelia trilobata L.invasion on protective enzymes,content of osmotic adjustment substances and chlorophyll content of three weeds were studied.The results showed that under invasion stress of Wedelia trilobata L.,activities of peroxidase (POD),catalase (CAT) and superoxide dismutase (SOD) as well as content of soluble protein,soluble sugar and chlorophyll in leaves of Bidens alba L.,Dicranopteris dichotoma L. and Commelina communis L.increased at different degree.Specially,SOD activities,soluble sugar content and chlorophyll content increased significantly.Three weeds made adaptive reaction to invasion of Wedelia trilobata L.through adjusting activities of protective enzymes,content of osmotic adjustment substances and photosynthetic pigment.
