Title: Photosynthetic characteristics and antioxidant capacity of centipedegrass under different shading levels
Abstract: The photosynthetic characteristics and antioxidant capacity of centipedegrass under different shading levels(50% and 70% of full sunlight)were studied.The results indicated that compared with the control(full sunlight),the contents of chlorophyll a and b were significantly increased,particularly at 50% shading level,however,the net photosynthetic rate(Pn)and light saturation point(LSP)in leaf were deceased.No significant changes were observed in MDA content and chlorophyll a/b ratio.With increase of shading level,SOD activity was decreased correspondingly,the leakage of electrolytes was increased.And the accumulation free proline was reduced.It could be concluded that antioxidant capacity of centipedegrass was decreased when growing in shading environment.
