Other claims from this paper (12)
- Intervention effect Ozone exposure reduced the mean leaf size and the leaf area of birch relative to ambient ozone.
- Intervention effect Ozone exposure accelerated autumn yellowing and loss of leaves of birch relative to ambient ozone.
- Intervention effect Ozone exposure increased palisade layer thickness of birch relative to ambient ozone.
- Association Ozone and nitrogen supply interacted to increase leaf biomass production, root dry weight and spongy intercellular space.
- Association Ozone and nitrogen supply interacted to decrease leaf loss, yellowing of leaves and palisade layer thickness.
- Association High nitrogen availability increased height growth, mean leaf size and leaf area of birch.
- Association High nitrogen availability increased the shoot/root ratio, leaf water content and stem dry weight of birch.
- Association High nitrogen availability decreased the number of leaves and the leaf dry mass per area of birch.
- Association High nitrogen availability retarded autumn senescence of leaves of birch.
- Association High nitrogen availability reduced the leaf and palisade layer thickness of birch.
- Association High nitrogen availability increased the intercellular space of the palisade layer of birch.
- Observation No significant differences in response to each treatment were found between the birch clones.
