| Abstract: | Li-6400 portable photosynthesis system was used to measure the photosynthetic parameters of Pinus tabulaeformis and Prunus armeniaca planted in the sunny slope in Daqing Mountains.The water use efficiency(WUE) was calculated according to WUC=Pn/Tr.The response processes of some parameters to SWC were studied,including net photosynthetic rate(Pn),carboxylation efficiency(Ce),transpiration rate(Tr),water use efficiency(WUE).The effects of different soil water stress on the photosynthesis and the fitting range... |
