The diffusive resistance and the transpiration rates of 35 species, both exotic and indigenous were measured at four study sites throughout Thailand. The diurnal changes of transpiration rate were observed from morning to evening. The diffusive resistance of most species temporally increased around noon. The transpiration rate fluctuated remarkably with the Photosynthetic Photon Flux Density (PPFD). The effect of leaf ages and the upper and the lower surfaces of leaf on the transpiration rates were discussed. Water consumption in stand level and the transpiration ratio were calculated for E. camaldulensis and A. mangium. E. camaldulensis showed higher water consumption but lower transpiration ratio based on stem biomass compared to A. mangium.
