Forests, 2023 Understanding the maturation stress and wood properties of poplar tension wood is critical for improving lumber yields and utilization ratio. In this study, the released longitudinal maturation strains (RLMS), anatomical features, physical and mechanical properties, and nano-mechanical properties of the cell wall were analyzed at different peripheral ...

Comparison of tension wood and normal wood for oxidative nanofibrillation and network characteristics [PDF]
Cellulose, 2020 AbstractCellulose nanofibrils (CNFs) are top-down nanomaterials obtainable from abundant lignocelluloses. Despite recent advances in processing technologies, the effects of variations in the lignocellulose structure and composition on CNF isolation and properties are poorly understood. In this study, we compared the isolation of CNFs from tension wood (

The influence of initial tension on blunting of chain saw blades and cutting efficiency
Leśne Prace Badawcze, 2018 The initial tension of the chainsaw is a decisive factor in making the operator’s work more efficient and at the same time it is a parameter that the operator can adjust and thus affect significantly.

Frontiers in Plant Science, 2021 Lignin in Populus species is acylated with p-hydroxybenzoate. Monolignol p-hydroxybenzoyltransferase 1 (PHBMT1) mediates p-hydroxybenzoylation of sinapyl alcohol, eventually leading to the modification of syringyl lignin subunits.

Tension Wood and Opposite Wood in 21 Tropical Rain Forest Species [PDF]
IAWA Journal, 2006 Wood samples were taken from the upper and lower sides of 21 naturally tilted trees from 18 families of angiosperms in the tropical rain forest in French Guyana. The measurement of growth stresses ensured that the two samples were taken from wood tissues in a different mechanical state: highly tensile stressed wood on the upper side, called tension ...

Possibility of using non-destructive spectrophotometery to detect the poplar tension wood and spruce compression wood in freshly cut and dried timbers [PDF]
تحقیقات علوم چوب و کاغذ ایران, 2012 In this study, the potential use of spectrophotometery and CIELAB technique was evaluated to detect reaction woods, including poplar tension wood and spruce compression wood. Thus, two trees of spruce ( Picea abies) and poplar (Populous nigra) containing

Precautions for the Structural Analysis of the Gelatinous Layer in Tension Wood [PDF]
IAWA Journal, 2005 The gelatinous layer (G-layer) of tension wood fibres in hardwood contributes to the mechanical function of the living tree and has significant consequences on properties of solid wood. Its size, shape and structure observed by optical or electron microscopy exhibits characteristic anatomical features.
