| Abstract: | Objective] Photosynthetic diurnal variation of Cyclobalanopsis gilva was researched in this paper.Method] using the Li-6400 portable photosynthesis system,diurnal dynamics of net photosythetic rate(Pn),transpiration rate(Tr),stomatal conductance(Cond) and Ci of C.gilva were studied.Result] diurnal dynamics curve of Pn of C.gilva appeared to be a double peak curve,but presented a single peak curve in Tr and Ccond and W curve in Ci. |
