Other claims from this paper (6)
- Intervention effect Chemlali was more drought resistant than Meski.
- Intervention effect Chemlali had a greater capacity for osmotic adjustment through solute accumulation than Meski.
- Mechanism Under acute water stress, the effect of osmoregulation on leaf cell turgor was largely counteracted by xylem cavitation.
- Observation Both olive varieties were highly resistant to embolism formation.
- Observation In Meski, the xylem water potential inducing 50% loss of stem conductivity approached -7 MPa.
- Observation In Chemlali, the xylem water potential inducing 50% loss of stem conductivity was only slightly less than in Meski.
