e6“The most ozone-tolerant genotypes were hybrid aspen clones, indicating that populations that have already experienced selection for ozone-tolerant genotypes should be used to cross-breed with ozone-sensitive populations to achieve tolerance of a climate with increasing tropospheric ozone concentrations”

- 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 differed significantly in their ozone responses.
- Observation Aspen clones were clustered into ozone sensitivity groups based on their growth responses.
- Recommendation Populations that have experienced selection for ozone-tolerant genotypes should be used to cross-breed with ozone-sensitive populations.
