Other claims from this paper (5)

Association Stem stiffness declined with leaf node frequency.
Observation Node and gap tissue contained twisted and contorted cells.
Mechanism The authors propose that node cells may absorb compressive and tensile stresses.
Mechanism The authors link node frequency to vertical expansion, light capture, and wind-stress damping.
Observation Ultimate stems were the most bendable.
