- Intervention effect Ozone reduced photosynthetic capacity and quantum yield in shaded sugar maple.
- Observation Ozone did not reduce photosynthetic capacity and quantum yield in the contrasting light treatments.
- Intervention effect Elevated ozone decreased CO 2 saturated photosynthesis in unshaded poplar.
- Intervention effect Elevated ozone decreased CO 2 saturated photosynthesis in shaded poplar.
- Intervention effect Elevated ozone decreased CO 2 saturated photosynthesis in shaded sugar maple.
- Intervention effect Ozone significantly reduced chlorophyll in unshaded and shaded poplar.
- Intervention effect Older leaves of unshaded poplar had greater ozone-related chlorophyll reductions than older shaded leaves.
- Intervention effect Ozone significantly reduced chlorophyll in shade-grown maple leaves.
