Other claims from this paper (7)
- Observation PItot decreased over time in lower crown leaves.
- Observation PItot increased over time in upper crown leaves.
- Intervention effect Ozone depressed fluorescence parameters in basal leaves of well-watered plants.
- Intervention effect Ozone had little or no damaging effect on medium or upper crown leaves.
- Intervention effect Ozone stress increased PItot and IP-phase in upper leaves.
- Intervention effect Water stress increased PItot at all crown levels.
- Mechanism The authors suggest that young upper leaves partially compensate for ozone-related photosynthesis loss.
