Other claims from this paper (6)
- Observation Pine and spruce provenance responses to ozone differed significantly in germination and shoot increment.
- Intervention effect Ozone immediately reduced germination of Northern pine provenances.
- Intervention effect Biomass reductions appeared in all pine provenances during the second ozone exposure year.
- Observation Spruce was more tolerant to elevated ozone.
- Mechanism The authors conclude pine seedling development is vulnerable to increasing ozone.
- Recommendation The authors recommend attention to provenance selection.
