Taking the precious timber tree of Phoebe bournei as experimental materials ,the photosynthetic pigment contents and chlorophyll fluorescence parameters in leaves of 21 provenances of Phoebe bournei were measured and analyzed .The results showed that the photosynthetic pigment contents varied significantly among the 21 provenances of Phoebe bournei.The provenances of the number 8 and 5 had higer chlorophyll content , which indicated they had better capability of light energy utilization;the value of PSⅡmaximal photochemical efficiency (Fv/Fm),the PSⅡpotential photochemical efficiency (Fv/Fo),the photochemicalquenching coeffi-cient (Qp),the PSⅡactual photochemical efficiency ( Qy),and the PSⅡquantum yield of linear electron (ΦPSⅡ) of the provenances of the number 8 and 5 were higer than those of the other provenances ,and the values of non-photochemical quenching coefficient ( NPQ) of the provenances of number 8,5 and 11 were higer than those of the other provenances ,which showed number 8 and 5 had better photosynthetic physiologi-cal function than the other provenances .
