Other claims from this paper (9)
- Intervention effect In wheat, O2 uptake was maximum at 60 microliters per liter CO2 at 2% or 21% O2.
- Intervention effect At lower CO2 concentrations, O2 uptake was strongly inhibited in wheat.
- Intervention effect At lower CO2 concentrations, photosynthetic O2 evolution was inhibited in wheat.
- Observation At 2% O2, a substantial O2 uptake remained in wheat even at high CO2 levels.
- Observation No saturation of O2 uptake was observed at high light intensities in wheat.
- Observation No significant change in gas-exchange patterns occurred in wheat during a long period of plant life.
- Observation Wheat adapted to low light intensities after 3 hours of illumination.
- Mechanism Functioning of the photosynthetic apparatus in wheat is regulated by electron acceptors and a specific action of CO2.
- Mechanism The O2 uptake behaviour and CO2 compensation point suggest persistence of mitochondrial respiration during photosynthesis in wheat.
