Other claims from this paper (12)
- Observation Light and dark CO2 evolution in leaves differed in temperature response.
- Association CO2 evolution in light rose from 17 to 35 degrees and then declined.
- Association CO2 evolution in darkness increased continuously up to 40 degrees.
- Association Light intensity affected CO2 evolution in light.
- Observation Below 35 degrees at 1800 ft-c, CO2 evolution was greater in light than darkness.
- Observation Above 35 degrees at 1800 ft-c, CO2 evolution was lower in light than darkness.
- Association Apparent photosynthesis decreased as temperature rose from 20 to 40 degrees.
- Association Apparent photosynthesis was affected by light intensity.
- Association Apparent photosynthesis was affected by oxygen concentration.
- Mechanism Between 20 and 30 degrees at 21% oxygen, increased light CO2 evolution primarily explained the decrease in apparent photosynthesis in dicot leaves.
- Association Corn had little temperature effect on apparent photosynthesis.
- Mechanism The differing temperature responses support light and dark CO2 evolution as two distinct processes.
