Other claims from this paper (5)
- Association Stem stiffness declined with leaf node frequency.
- Association Xylem density declined with leaf node frequency in adult trees.
- Observation Node and gap tissue contained twisted and contorted cells.
- Mechanism The authors link node frequency to vertical expansion, light capture, and wind-stress damping.
- Observation Ultimate stems were the most bendable.
