- Intervention effect Ozone exposure reduced Rubisco, chlorophyll and carotenoid contents in birch leaves.
- Intervention effect Ozone exposure reduced starch and nutrient contents in birch leaves.
- Intervention effect Ozone exposure lowered stomatal conductance in birch.
- Intervention effect Ozone exposure decreased new shoot growth and net assimilation rate in birch.
- Intervention effect Ozone exposure decreased shoot dry weight by 7·5% over the long term.
- Intervention effect Ozone exposure decreased root dry weight by 15·2% over the long term.

- Observation Relative growth rates showed a slow recovery in the two seasons after elevated ozone exposure ended.
- Observation In the sensitive clone, allocation shifted from growth towards defensive phenolics such as chlorogenic acid.
