- Association Predawn water potential declined with increasing water stress.
- Association Midday water potential remained unchanged with increasing water stress.
- Intervention effect Water stress reduced gas exchange.
- Intervention effect Elevated carbon dioxide increased photosynthetic rates.
- Intervention effect Elevated carbon dioxide reduced leaf conductance.
- Intervention effect Elevated carbon dioxide nearly doubled instantaneous transpiration efficiency.
- Intervention effect Elevated carbon dioxide decreased dark respiration.
- Intervention effect Water stress reduced dark respiration in trees at ambient carbon dioxide.
- Observation Willow had 56% lower whole plant hydraulic conductivity than poplar.
- Intervention effect Elevated carbon dioxide increased willow whole plant hydraulic conductivity by 14%.
- Intervention effect Poplar whole plant hydraulic conductivity was unresponsive to elevated carbon dioxide.
- Intervention effect Elevated carbon dioxide mitigated water stress effects in willow.
- Intervention effect Elevated carbon dioxide did not mitigate water stress effects in poplar.
