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 ...

Tree mechanics and wood mechanics: relating hygrothermal recovery of green wood to the maturation process [PDF]
Annales des Sciences Forestières, 1994 Mecanique de l'arbre et mecanique du bois. Relation entre la recouvrance hygrothermique du bois vert et le processus de maturation. Les contraintes de croissance peuvent etre abordees du double point de vue de la tenue mecanique des arbres et de l'histoire du chargement applique sur le materiau jusqu'a l'abattage de l'arbre. Elles trouvent leur origine

Journal of Forest Science, 2008 The aim of this study was to compare the structure of beech juvenile and mature wood in relation to wood density. The comparative analysis between juvenile and mature wood examined the diameter of vessels, the width and height of pith rays, and the ...

Viscoelastic Behaviour of Maturating Green Poplar Wood [PDF]
, 2013 Trees can modify the orientation of their trunk and branches by asymmetrical production of reaction wood. Even though biomechanical models that simulate gravitropic movements are proposed in the literature, recent studies show that they cannot fit the righting-up movement of young, fast growing poplar trees at the intra annual scale.

Annals of Forest Science, 2023 Key message Larger differences of maximum load among families were found in mature wood compared to juvenile wood, suggesting the possibility of improving mature wood with higher resistance to rupture and maintaining characteristics of material in Larix ...

Dimensional Stabilization of Wood Originating from Small-diameter Trees through Heat Treatment
BioResources, 2014 Small-diameter wood resulting from thinning operations is an important secondary wood resource. Compared to wood originating from mature trees of the same species, it is less stable in shape and dimension when exposed to environmental humidity changes ...

Effect of ring shakes on mechanical properties of chestnut wood from a Greek coppice forest
The Forestry Chronicle, 2018 Measurements of several mechanical and physical properties were carried out to detect possible variations between ring shaken and non-ring shaken logs or between different areas of wood from the same log (i.e., ring shaken log). Mature wood from the ring

New Phytologist, 2022 Whether sources or sinks control wood growth remains debated with a paucity of evidence from mature trees in natural settings. Here, we altered carbon supply rate in stems of mature red maples (Acer rubrum) within the growing season by restricting phloem
