- Intervention effect Twice ambient ozone caused chlorotic mottling and yellowing of current year needles in Scots pine.
- Intervention effect Chlorotic mottling was more pronounced at near zero UV-B than ambient UV-B.
- Intervention effect Twice ambient ozone reduced photosynthetic parameters in Norway spruce regardless of UV-B treatment.
- Observation Effects on photosynthetic capacity and carboxylation efficiency occurred only under near zero UV-B with twice ambient ozone.
- Observation Foliar symptoms developed faster in Scots pine than Norway spruce at higher accumulated ozone concentrations.
