Diurnal changes in gas exchange, chlorophyll fluorescence and leaf water potential (ψ leaf) were measured to determine the environmental and physiological factors that limit carbon gain in the horizontal leaves of Fagus crenata Blume at the canopy top. Although midday depression of the net CO2 assimilation rate (A n) and stomatal conductance (gH2O) were clearly evident on a fine day, the potential quantum yield of PS II (F v/F m) was fairly constant around 0.83 throughout the day.
