Abstract

To clarify the gas exchange characteristics of temperate broad-leaved tree species, we investigated net photosynthetic rate (Pn), stomatal conductance (Gw), and intrinsic water-use efficiency (WUE,=Pn/Gw) of leaves of 41 species grown in the arboretum within the campus of Forestry and Forest Products Research Institute. Maximum value of Pn (Pn_<max>) varied 9 to 24μmolCO_2m^<-2>s^<-1> among species, and was not different between deciduous and evergreen species. Maximum value of Gw (Gw_<max>) varied 50 to 900mmol m^<-2>s^<-1>, and was relatively high in deciduous species than evergreen species. WUE (Pn_<max>/Gw_<max>) varied 10 to 90×10^<-6>molCO_2molH_2O^<-1>, and was relatively high in deciduous species than evergreen species. Based on these gas exchange traits, we classified the 41 species into three categories; dry type, wet type, and medium type. In 21 species, results of this study coincided with the ecological traits of the species. However, the gas exchange traits were not consistent with the ecological traits in the other species.
