Other claims from this paper (4)
- Observation Needle and stem tracheids did not differ in bordered pit torus overlap.
- Method / resource Whole needle hydraulic conductance P50 from rehydration kinetics was significantly higher than needle xylem P50 from HRCT.
- Observation Native needle embolism appears limited.
- Mechanism Vulnerability segmentation appears valid only for whole needle hydraulic failure including extra-xylary pathways.
