Synopsis Rice seedlings maintain an appreciable net photosynthesis rate at low temperature (40 or 60° F.) and a wide range of light intensities. Low light intensities at a higher temperature (80° F.) result in net losses of CO 2 from the plants. Respiration losses increase with increasing temperature, and the light intensity required at the compensation point increases with increasing temperature.
