e0“Impacts of elevated tropospheric ozone and soil nitrogen amendment on two native European aspen ( Populus tremula L.) and eight hybrid aspen”
e5“There were significant differences in ozone responses among the clones, and we were able to cluster the clones into sensitivity groups based on their growth responses”

- Intervention effect Ozone decreased leaf-level net photosynthesis of aspen, particularly early in the growing season.
- Intervention effect Ozone decreased maximum quantum yield of photosystem II of aspen at the end of the growing season.
- Association Nitrogen amendment increased the growth of all plant parts of aspen.
- Association Nitrogen amendment mitigated the adverse effects of ozone on aspen.
- Observation Aspen clones were clustered into ozone sensitivity groups based on their growth responses.
- Observation The most ozone-tolerant aspen genotypes were hybrid aspen clones.
- Recommendation Populations that have experienced selection for ozone-tolerant genotypes should be used to cross-breed with ozone-sensitive populations.
