【Objective】To select broad-leaf species with high photosynthetic efficiency,we analyzed the light response curve of photosynthesis among Eucalyptus grandis×E.urophylla,Castanopsis fissaand Castanopsis hystrixin the country of Lingtian,Guilin,Guangxi.【Methods】The Li-6400 portable photosynthesis system was used to measure the light response curves among tree species.【Results】There was little difference in net photosynthetic rate(Pn)among species when photosynthetically active radiation(PAR)began to increase,w...
