- Intervention effect Ozone reduced pine net assimilation rate after 79 days.
- Intervention effect Elevated CO2 increased pine net assimilation rate after 79 days.
- Intervention effect Total pine mass accumulation did not differ significantly with gas exposure, though ozone treated plants tended smaller.
- Intervention effect Elevated ozone shifted allocation priority toward shoots over roots.
- Intervention effect Elevated ozone significantly increased pine shoot nitrogen concentration.
- Intervention effect Elevated CO2 significantly increased photosynthetic N use efficiency.
- Intervention effect Ozone decreased photosynthetic N use efficiency.
- Intervention effect Elevated CO2 reduced symbiosis mediated pine nitrogen uptake.
- Intervention effect Ozone reduced symbiosis mediated pine nitrogen uptake.
- Mechanism Elevated CO2 may raise the carbon cost of symbiotic nitrogen uptake.
- Mechanism Ozone may shift pine nitrogen acquisition toward root uptake.
