Strength changes in ash, beech and maple wood modified with a N-methylol melamine compound and a metal-complex dye

open access: yes, 2013
Ash, beech and maple wood was modified with aqueous solutions of methylated N-methylol melamine (NMM) and a metal-complex dye (BS) consisting of 10, 20, and 30 % NMM and 5 % BS.

Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

open access: yesNew Phytologist, EarlyView.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.

Fine‐root trait variation in temperate trees follows arc‐shape pattern along deep soil profiles

open access: yesNew Phytologist, EarlyView.
Root trait variation along the soil depth profile in four temperate tree species. Summary Roots are plants' interface with the soil, controlling access to water and nutrients. Yet, fine‐root trait variation along deep soil profiles and its functional implications remain poorly understood.

Temperate tree species show cross‐tolerance to heat, drought, and late spring‐frost stress

open access: yesNew Phytologist, EarlyView.
Significant cross‐tolerance of leaf traits to heat, drought and late spring‐frost were found. (a) Turgor loss point vs lethal spring‐frost temperature. (b) Heat thermal threshold temperature vs lethal spring‐frost temperature. (c) Heat thermal threshold temperature vs turgor loss point.

Discolouration and Chemical Changes of Beech Wood After CO2 Laser Engraving

open access: yes
This study evaluated the influence of infrared laser radiation produced by a CO2 laser, performing under different engraving parameters, on the colour changes and chemical composition of a beech wood surface. The results showed that the lightness clearly

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Effects of some impregnation chemicals and water repellents on the hygroscopicity of beech wood

open access: yes, 2007
Salt based chemicals tend to increase in hygroscopicity of wood. This phenomenon is known as one of the disadvantages of these salts in wood preservation in spite of their protective effectiveness against biological agents and fire.
