e0“Scotch pine seedlings (Pinus sylvestris L.) were subjected to 6 week photoperiod and thermoperiod treatments to induce different levels of cold acclimation”
e2“There was a close correlation between relative water content and water content of woody stems and needles as well as a decrease in xylem pressure potentials of hardy needles, indicating that the reduction in water content was at least partially due to increased water deficit”

Other claims from this paper (8)
- Intervention effect Cold acclimation decreased water content in woody stems and needles of Pinus sylvestris.
- Intervention effect Cold acclimation did not change water content in roots and green stems of Pinus sylvestris.
- Association Xylem pressure potentials decreased in hardy needles of Pinus sylvestris.
- Association Transpiration rates decreased in hardy shoots of Pinus sylvestris.
- Association The increased water deficit in Pinus sylvestris was not caused by increased water loss.
- Mechanism Reduced water uptake may account for the shoot water deficits, through decreased root hydraulic conductance.
- Intervention effect Root hydraulic conductance and transpiration rate returned to non-acclimated levels after warm temperature exposure.
- Association ABA levels in root exudate were highest in the morning from non-acclimated Pinus sylvestris plants.
