Other claims from this paper (4)
- Intervention effect Even with more than 25% open vessels, xylem embolism thresholds P12, P50 and P88 resemble those of branches with no open vessels.
- Observation Native embolism in Eucalyptus globulus is 10% under natural conditions.
- Observation Native embolism in Acacia mearnsii is 20% under natural conditions.
- Association Pre-existing native embolisms at the field percentages (<25%) would not increase xylem embolism vulnerability.
