The photosynthetic rate measured at 20°C was higher in rice grown under 20/18°C day/night temperature and 350 μmoI quanta m−2s−1 than in rice grown under 25/20°C and 1,000 μmol quanta m−2s−1, whereas there was no difference in the photosynthetic rate measured at 25°C between rice grown in these two ways. This difference was suggested to be caused by an enhanced ribulose-l,5-bis-phosphate-regeneration capacity in the low-temperature/ir-radiance-grown rice.

Keywords: Gas exchange (photosynthesis); Low irradiance; Low temperature; Oryza sativa; Ribulose-1,5-bisphosphate (RuBP) regeneration capacity
