Abstract:
Impact of drought stress,high temperature stress,low temperature stress and diverse intensities of shade on activity of POD，SOD，content of soluble protein，chlorophyll，etc.of Bredia sinensis was studied.The results showed that net photosynthesis rate falled to a certain extent，but content of chlorophyll somewhat increased，as soil moisture decreased；activity of POD，SOD，content of soluble protein of Bredia sinensis showed a trend of first rising and then falling，only extent of rising or falling was different，as temperature increased under high temperature stress；activity of POD，SOD of Bredia sinensiss also showed a trend of first rising and then falling，as temperature falled under the low temperature stress；content of chlorophyll of Bredia sinensis rised and the light saturation point(LSP) and the light compensation point(LCP) were low，as shading rate increased.It showed the drought resistant of Bredia sinensis was not strong，but shade tolerance was strong,and cold and heat tolerance was a certain extent strong.
