Other claims from this paper (10)
- Intervention effect Increasing ozone from 19 to 42 nmol mol−1 reduced root dry weight.
- Intervention effect The 19-to-42 ozone increase did not reduce shoot dry weight.
- Intervention effect Ozone at 44 nmol mol−1 also decreased shoot dry weight.
- Intervention effect Higher ozone concentrations further decreased shoot and root dry weights.
- Intervention effect Moderate ozone exposure increased plant height and leaf size.
- Intervention effect Further ozone exposure decreased height and leaf size.
- Observation Birch provenances generally responded similarly to ozone.
- Association Shoot and root dry weights correlated best with AOT40 and AOT30.
- Association Shoot dry weight was estimated to decrease 10% at AOT40 of 7.0 μmol mol−1‐h.
- Association Visible ozone injury correlated most strongly with AOT40.
