Gravity sensing, a largely misunderstood trigger of plant orientated growth

open access: yesFrontiers in Plant Science, 2014
Gravity is a crucial environmental factor regulating plant growth and development. Plants have the ability to sense a change in the direction of gravity, which leads to the re-orientation of their growth direction, so-called gravitropism.

The Cytoskeleton and Its Role in Determining Cellulose Microfibril Angle in Secondary Cell Walls of Woody Tree Species

open access: yesPlants, 2020
Recent advances in our understanding of the molecular control of secondary cell wall (SCW) formation have shed light on molecular mechanisms that underpin domestication traits related to wood formation. One such trait is the cellulose microfibril angle (

The Effect of Alkali Concentration and Hydrolysis Time on the Production of Oxalic Acid from Wood Sawdust Waste by Alkali Hydrolysis Process

open access: yesChemical Engineering Transactions, 2023
Mahogany wood is a type of wood often found in sawmills because the wood grows faster than other types of wood, so a lot of mahogany sawdust is wasted and not utilized in a product that is discarded and has economic value.

The Molecular Mechanisms of Reaction Wood Induction [PDF]

open access: yes, 2013
The book is an essential reference source on reaction wood for wood scientists and technologists, plant biologists, silviculturists, forest ecologists, and anyone involved in the growing of trees and the processing of wood. It brings together our current understanding of all aspects of reaction wood, and is the first book to compare and discuss both ...

Growth Stresses in Trees: The Nature, Formation and Manifestations of Growth Stresses

open access: yesForestist, 2007
Growth stresses are characteristic of normal growing trees and occur in both hardwoods and softwoods. Growth stresses are not visible and can not be measured directly. However, theyare estimated by strain measurements in wood.

Physical and Mechanical Properties of Reaction Wood [PDF]

open access: yes, 2013
Reaction wood produces very peculiar maturation stresses at the tree periphery i.e. compressive stress or very high tensile stress, for compression and tension wood respectively, as compared to moderately high tensile stress for normal wood. This means that both its mechanical state and its mechanical and physical properties differ from normal wood ...

Investigation the acoustic behavior of poplar and spruce species reaction wood using ultrasonic technique [PDF]

open access: yesتحقیقات علوم چوب و کاغذ ایران, 2012
The acoustic behavior of reaction and normal woods, phase velocity, group velocity and attenuation coefficients in the main directions for two wood species (Populus deltoids & Picea abies), were measured and compared.

Comparison of Reaction Wood and Normal Wood of Some Commercial Tree Species

open access: yesDrvna Industrija, 2023
This study aims to analyze the reaction wood samples for some industrial tree species naturally grown in Kastamonu province in Turkey and compare them with the relevant standards.

Preparation and Luminescence Properties of Europium(III) Ternary Complex-modified Poplar Wood-based Materials [PDF]

open access: yesMaterials Research, 2019
Inspired by the ultraviolet induced properties of biological materials, we developed fluorescent wood as a new type of functional material which can be applied to anti-counterfeit label technology and wood-emitting artwork.

Soil conditions required for reaction wood formation of drunken trees in a continuous permafrost region

open access: yesArctic, Antarctic, and Alpine Research, 2020
Black spruce trees lean to form “drunken” forest on degrading permafrost; however, the causes of tree leaning on continuous permafrost remain unclear. Leaning events are recorded by reaction wood formation in tree rings, and it remains unclear what soil ...
