Other claims from this paper (6)
- Intervention effect At low VPD, ozone reduced biomass, leaf area and seed yield substantially in both snap bean genotypes.
- Intervention effect In clean air, high VPD reduced biomass and yield in both snap bean genotypes compared with low VPD.
- Mechanism High VPD is hypothesized to reduce snap bean growth and yield through unsustainable transpiration and water deficits.
- Intervention effect At low VPD, ozone increased transpiration relative to clean air in snap bean.
- Association Ozone-related biomass reductions at low VPD were proportionally higher in genotype S156 than in R123.
- Recommendation Assessments of potential ozone impacts on vegetation should incorporate interacting factors such as VPD.
