Claim · model-written summary
The gain in flow from growing at 5 and measuring at 20 degrees C was similar to the loss from growing at 20 and measuring at 5 degrees C.

- Intervention effect At 5 degrees C, aspen root growth was completely inhibited relative to 20 degrees C.
- Intervention effect At 10 degrees C, aspen root growth was inhibited by 97% relative to 20 degrees C.
- Intervention effect The 5 and 10 degree C treatments reduced aspen shoot growth, leaf size and total leaf area.
- Intervention effect The 5 and 10 degree C treatments inhibited aspen root water flow.
- Observation Aspen grown at 5 degrees C for 28 days showed increased root water flow when measured at 20 degrees C.
- Association Reduced root flow in seedlings grown at 5 and 10 degrees C coincided with decreased stomatal conductance, net assimilation and shoot water potentials.
- Association Root water flow correlated positively with aspen leaf size, total leaf area and shoot length.
- Association Root water flow correlated positively with new aspen root growth.
- Intervention effect Transfer from 5 to 20 degrees C for 24 hours increased root flow, shoot water potential and net photosynthesis.
- Intervention effect Transfer from 10 to 20 degrees C slightly increased shoot water potential.
- Intervention effect Transfer from 20 to 5 degrees C greatly reduced root flow, stomatal conductance and net photosynthesis.
- Intervention effect Transfer from 20 to 5 degrees C slightly decreased shoot water potential.
