Other claims from this paper (6)
- Intervention effect Twenty minute tension relaxation produced less embolism than native tension harvest.
- Method / resource Relaxed petioles gave vulnerability curves like direct microCT curves.
- Observation Xylem refilling occurred only after overnight hydration.
- Method / resource The authors conclude that short relaxation reliably quantifies native embolism.
- Mechanism The authors infer that stomatal regulation avoids transpiration induced cavitation.
- Observation The authors infer a cavitation resistance strategy for grapevines.
