Deformation induced by ethanol substitution in normal and tension wood of chestnut and simarouba
Résumé
Normal wood swells in the longitudinal direction during serial ethanol substitution and this swelling is larger when the MFA is larger. However, tension wood shrinks under these conditions. This was observed both in a species with G-layer and in a species lacking a G-layer. We propose a mechanism explaining this difference in behaviour, based on the differential relaxation of internal stress during molecular substitution.
