PLoS ONE, 2022 Tree improvement programs often focus on improving productivity-related traits; however, under present climate change scenarios, climate change-related (adaptive) traits should also be incorporated into such programs.

Wood anatomy of boreal species in a warming world: a review
iForest - Biogeosciences and Forestry, 2020 Global warming is affecting tree growth and forest productivity, especially in the Northern boreal ecosystems. Wood quality, which is largely determined by anatomical traits of wood, is vital for the forest industry and global carbon sequestration ...

Models for predicting microfibril angle variation in Scots pine [PDF]
Annals of Forest Science, 2012 Context Microfibril angle (MFA) is one of the key determinants of solid timber performance due to its strong influence on the stiffness, strength, shrinkage properties and dimensional stability of wood.

Nanostructural deformation of high-stiffness spruce wood under tension
Scientific Reports, 2021 Conifer wood is an exceptionally stiff and strong material when its cellulose microfibrils are well aligned. However, it is not well understood how the polymer components cellulose, hemicelluloses and lignin co-operate to resist tensile stress in wood ...

Journal of Wood Science, 2022 The current stumpage price in harvesting of a 50-year-old sugi (Japanese cedar, Cryptomeria japonica) plantation is not enough to motivate forest owners to reforest. Therefore, it is vital to reduce the cost for reforestation after logging as well as for

Frontiers in Forests and Global Change, 2022 While it is known that modifying the hydroxyls in wood can improve the decay resistance; what is often missing in the literature is whether these modifications alter wood nanostructure, and how these changes correlate to the improved decay resistance ...

The Influence of Microfibril Angle on the Wood Stiffness Parameters
Procedia Engineering, 2017 Abstract The cellulose microfibrile angles /MFA/ in tracheids of spruce wood were observed using the polarization microscope treatment. For the wood samples tested, the modulus of elasticity in compression strain was performed. The close dependency of the MFA values on to the parameters of modulus of elasticity was established.

The influence of the microfibril angle on wood stiffness: a continuum micromechanics approach
Computer Assisted Methods in Engineering and Science, 2022 Wood exhibits an intrinsic structural hierarchy. It is composed of wood cells, which are hollow tubes oriented in the stem direction. The cell wall is built up by stiff cellulose fibrils which are embedded in a soft polymer matrix.

Fiber Characteristics and Mechanical Properties of Oxytenanthera abyssinica
Plants, 2023 Unlike the culm hollow structure of most bamboo species, Oxytenanthera abyssinica has a unique solid or semi-solid culm, which may endow it with superior mechanical performance.
