Transverse shrinkage in G-fibers as a function of cell wall layering and growth strain [PDF]
Wood Science and Technology, 2007 Transverse drying shrinkage was measured at microscopic and mesoscopic levels in poplar wood characterised by an increasing growth strain (GS), from normal to tension wood. Results show that: (a) The drying shrinkage, measured as a relative thickness decrease, was significantly higher for G-layer (GL) than the other layers (OL), GL shrinkage was not ...

Transverse shrinkage variations within tree stems of Melia azedarach planted in northern Vietnam [PDF]
Journal of Wood Science, 2018 This study quantified variations within tree stems in tangential shrinkage (αT), radial shrinkage (αR), and tangential/radial shrinkage ratio (αT/αR) of Melia azedarach grown in two different sites in northern Vietnam. The overall values of αT, αR, and αT/αR were 7.05%, 4.38%, and 1.64, respectively.
