Claim · model-written summary
Sampling methods can generate PLC patterns that look like repair under tension, because excision induces embolism depending on xylem tension or gas supersaturation
- Taxon
- red maple and white ash
Fraxinus americana

Other claims from this paper (6)
- Intervention effect In red maple and white ash, PLC was higher in the afternoon when samples were excised under water at native xylem tensions than when tensions were relaxed first
- Intervention effect In red maple, cutting under tension had a dramatic effect on bench-drying vulnerability curves
- Intervention effect In sugar maple, cutting under tension had a moderate effect on bench-drying vulnerability curves
- Intervention effect In paper birch, cutting under tension had no effect on bench-drying vulnerability curves
- Intervention effect Air injection of cut red and sugar maple branches at 0.1 and 1.0 MPa gave PLC greater than predicted from vulnerability curves for samples cut 2 min after depressurization
- Intervention effect PLC in red and sugar maple returned to expected levels for samples cut after 75 min after air injection
