The physiological basis of photosynthesis during winter was investigated in saplings of five evergreen broad-leaved species ( Camellia japonica  L.,  Cleyera japonica  Thunb.,  Photinia glabra  (Thunb.) Maxim.,  Castanopsis cuspidata  (Thunb.) Schottky and  Quercus glauca  Thunb.) co-occurring under deciduous canopy trees in a temperate forest. We focused on temperature dependence of photosynthetic rate and capacity as important physiological parameters that determine light-saturated rates of net photosynthesis at low temperatures during winter. Under controlled temperature conditions, maximum rates of ribulose bisphosphate carboxylation and electron transport ( V  cmax  and  J  max , respectively) increased exponentially with increasing leaf temperature. The temperature dependence of photosynthetic rate did not differ among species. In the field, photosynthetic capacity, determined as  V  cmax  and  J  max  at a common temperature of 25 °C ( V  cmax  (25)  and  J  max  (25) ), increased until autumn and then decreased in species-specific patterns. Values of  V  cmax  (25)  and  J  max  (25)  differed among species during winter. There was a positive correlation of  V  cmax  (25)  with area-based nitrogen concentration among leaves during winter in  Camellia  and  Photinia . Interspecific differences in  V  cmax  (25)  were responsible for interspecific differences in light-saturated rates of net photosynthesis during winter.
