Abstract：As the important forest resource of tropical and subtropical plants, high quality rattans are important materials for processing and utilization which have great economic value. Leaf photosynthetic capacity has an important effect on the formation of rattan. The chlorophyll fluorescence parameters of Daemonorops jenkinsiana, Calamus faberii and C.balansaeanus were measured using chlorophyll fluorescence spectrometer, which will provide reference for the study on photosynthetic capacity of rattan and the selection of appropriate cultivation conditions. The result indicated that under laboratory conditions the value of photochemical efficiency Y (Ⅰ) in C.balansaeanus was the highest one, followed by those in C. faberii and D. jenkinsiana, and the value of Y (Ⅱ) in C. faberii was the highest one, followed by those in D. jenkinsiana and C.balansaeanus. The non-photochemical quenching coefficient (qN) ranked from high to low was in C. faberii, D. jenkinsiana and C.balansaeanus, and the photochemical quenching coefficient (qP) in C.balansaeanus wais the highest one, followed by those in D. jenkinsiana and C. faberii. Besides, the electron transport rate (ETR) of PSⅠranked from high to low was in C.balansaeanus, C. faberii and D. jenkinsiana, while that of PSⅡin C. faberii was the highest one, followed by those in D. jenkinsiana and C.balansaeanus. The average values of Fv/Fm of three rattan species ranged from 0. 78 to 0. 8, in which the value of Fv/Fm in C. faberii was obviously higher than those in other rattan species (P < 0. 01). Therefore, it could be concluded that under the laboratory conditions the photosynthetic efficiency of C.balansaeanus was the highest, followed by D. jenkinsiana and C. faberii, and C. faberii had the highest ability of photoprotection, followed by D. jenkinsiana and C.balansaeanus.
