Other claims from this paper (9)
- Intervention effect Drought caused leaf osmotic adjustment in all three oak species, lowering osmotic potentials by 0.25 to 0.60 MPa.
- Intervention effect Drought adjusted root osmotic potential in Q. stellata.
- Intervention effect Drought increased root tissue elasticity in Q. macrocarpa.
- Intervention effect Drought increased root tissue elasticity in Q. alba.
- Observation At full saturation, leaf osmotic potential was generally below root osmotic potential.
- Observation Leaf and root osmotic potentials at turgor loss were similar.
- Observation Roots lost turgor at lower relative water content than leaves.
- Observation Root water potential fell more gradually with dehydration than leaf water potential.
- Observation Roots had greater relative tissue capacitance than leaves.
