Other claims from this paper (9)
- Intervention effect Mature Phaseolus leaflets had an 80% reduction in light-saturated CO2 assimilation after three hours of treatment.
- Observation Young bean leaflets were photoinhibited.
- Observation Mature leaflets did not show the partial recovery seen in young leaflets.
- Association Photoinhibition depended markedly on exposure time.
- Intervention effect Photoinhibition was absent above 7% oxygen under CO2-free nitrogen.
- Intervention effect Photoinhibition was absent at 1% oxygen when intercellular CO2 reached the compensation point.
- Intervention effect Treatment reduced the light-limited CO2 assimilation rate.
- Intervention effect Apparent quantum yield decreased after treatment.
- Mechanism The authors infer that photorespiratory internal CO2 generation prevents photoinhibition.
