Shinkage of the gelatinous layer of poplar and beech tension wood

Clair Bruno, Thibaut Bernard. 2001. Shinkage of the gelatinous layer of poplar and beech tension wood. IAWA Journal, 22 (2) : 121-131.

Résumé : Macroscopic longitudinal shrinkage of beech and poplar tension wood is higher than in normal wood. This shrinkage is the result of mechanical interactions of cell wall layers. SEM observation of cut, dried surfaces showed that longitudinal shrinkage is much greater in the gelatinous layer than in other layers. AFM topographic images of the same cells, both in water and in air-dry conditions, confirm this result. Measurements on sections indicate around 4.7% longitudinal shrinkage for the G layer.
