Shape Changes in Hornbeam (Carpinus betulus L.) Lumber Induced by Spiral Grain

BioResources
Hornbeam (Carpinus betulus L.) wood often has a spiral grain character, which contributes to shape instability in the resulting products. Spiral grain refers to the deviation of wood fibers from the longitudinal axis. This study identified and quantified

Responses in leaf water status of Quercus castaneifolia C.A.Mey and Carpinus betulus L. exposed to cement dust pollution in Northern Iran

Journal of Forest Science, 2023
Industrial air pollution, particularly cement dust, affects the leaf water status and resource utilisation and finally decreases primary production. Evaluating the relative water content (RWC), leaf mass per unit area (LMA), specific leaf area (SLA), and

Effects of climate change on the ecological niche of common hornbeam (Carpinus betulus L.)

Ecological Informatics, 2021
Abstract There is an urgent need to conduct scientific research in order to comprehend the impact of climate change on the geographical distribution of species that constitute an ecological niche. To meet this need, the current and future distribution areas of a species can be predicted by applying machine learning techniques.

Comparitive study of different hornbeams (carpinus betulus L.)

Gradus
The industrial application of hornbeam is significantly hindered by its fluted growth, mainly due to the poor output of the sawmill. Our study seeks to enhance the understanding of wood science and the wood business by examining the physical-mechanical characteristics of cylindrical and fluted hornbeams, while considering various site factors. Hornbeam

Thinning effects on soil and microbial respiration in a coppice-originated Carpinus betulus L. stand in Turkey [PDF]

iForest - Biogeosciences and Forestry, 2016
Effects of thinning on soil respiration and microbial respiration were examined over a 2-year period (2010-2012) in a coppice-originated European hornbeam (Carpinus betulus L.) stand in Istanbul, Turkey. Four plots within the stand were selected; tree density was reduced by 50% of the basal area in two plots (thinning treatment), and the other two ...

Evaluation of the Chemical Stability, Membrane Permeability and Antiproliferative Activity of Cyclic Diarylheptanoids from European Hornbeam (Carpinus betulus L.). [PDF]

Int J Mol Sci, 2023
Four cyclic diarylheptanoids—carpinontriols A (1) and B (2), giffonin X (3) and 3,12,17-trihydroxytricyclo [12.3.1.12,6]nonadeca-1(18),2(19),3,5,14,16-hexaene-8,11-dione (4)—were isolated from Carpinus betulus (Betulaceae).

Drought Effects on Physiology and Biochemistry of Pedunculate Oak (Quercus robur L.) and Hornbeam (Carpinus betulus L.) Saplings Grown in Urban Area of Novi Sad, Serbia

South-East European Forestry, 2016
Background and Purpose: Water stress is one of the major problems for urban trees. It affects a wide range of plant responses, from changes at the cellular level to the reduction in growth rates.

The Differences in Shape Stability for Hornbeam (Carpinus betulus L.) Lumber with and without Spiral Grain

Applied Sciences
Spiral grains are one of the most important tree growth defects that can remarkably affect the shape stability of lumber. This growth defect is observed by an oblique arrangement of axially oriented cell elements in the wood. This research focused on identifying and measuring selected shape changes caused by the spiral grains in the log.

Testing common hornbeam (Carpinus betulus L.) acetylated with the Accoya method under industrial conditions

iForest - Biogeosciences and Forestry, 2017
Hornbeam wood is known for its high density, hardness, toughness, and wear resistance, but due to its low durability (Class 5 according to EN 350), limited wood quality, and rather small sawmill yield, it is mainly utilized as firewood today.
