Measuring wood specific gravity… correctly
GB Williamson, MC Wiemann - American Journal of Botany, 2010 - Wiley Online Library
The specific gravity (SG) of wood is a measure of the amount of structural material a tree
species allocates to support and strength. In recent years, wood specific gravity, traditionally …

Diversity in the organisation and lignification of tension wood fibre walls–A review
Tension wood, a tissue developed by angiosperm trees to actively recover their verticality,
has long been defined by the presence of an unlignified cellulosic inner layer in the cell wall …

Structural characteristics of reaction tissue in plants
To maintain or adjust posture under the challenges of gravity and increased self-weight, or
the effects of light, snow, and slope, plants have the ability to develop a special type of tissue …

Evidence of the late lignification of the G-layer in Simarouba tension wood, to assist understanding how non-G-layer species produce tensile stress
To recover verticality after disturbance, angiosperm trees produce 'tension wood'allowing
them to bend actively. The driving force of the tension has been shown to take place in the G …
