Development of Douglas fir merchantable stem volume model in the conditions of the Czech Republic
(Česká akademie zemědělských věd, 2023)
A precise merchantable stem volume model of Douglas fir [Pseudotsuga menziesii (Mirb.) Franco] is missing in the Czech Republic. The aim of this study was to fit a new model through the reparametrization of volume equations ...
Properties of lightweight particleboard made with sunflower stalk particles in the core layer
(Elsevier Science BV, 2023)
In this study we assessed the efficacy of manufacturing lightweight particleboards using sunflower (Helianthus annuus L.) stalk particles. Three-layer lightweight particleboards with target densities of 350, 450 and 550 ...
Effect of different stand densities on xylem and phloem formation in Norway spruce plantations
(Brill, 2023)
Preliminary results of an investigation of the thinning effect on Norway spruce tree growth in terms of xylogenesis and phloemogenesis are presented. Three plots were selected where the stand densities were reduced by ...
Comparison of Methods for Estimating Damage by Wild Ungulates on Field Crops
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2023)
High numbers of large ungulates are locally accompanied by high levels of damage to field crops, causing economic losses and increased costs for the protection of agricultural fields. Quantifying the levels of damage can ...
Artificial Weathering Resistance and Biological Durability of Surface-Charred Beech Wood Combined with Linseed Oil Coating
(North Carolina State University, 2023)
Specimens of European beech wood (Fagus sylvatica L.) charred at 250 oC (4 min), 300 oC (2 min), and 350 oC (1 min) in combination with linseed oil coating were studied. The influence of the surface charring process and ...
Physical Properties of Silver Fir (Abies alba L.) Wood Cladding Modified by Traditional Japanese Charring Method
(North Carolina State University, 2023)
Silver fir (Abies alba L.) wood samples were charred on one surface using an enhanced version of the traditional Japanese Yakisugi method. The 15 charred boards obtained from five charring chimneys were divided into three ...
Sequence and phylogenetic analysis of a novel alphaendornavirus, the first virus described from the oomycete plant pathogen Phytophthora heveae
(Springer Wien, 2023)
Here, we report the discovery and complete genome sequence of a novel virus, designated as "Phytophthora heveae alphaendornavirus 1" (PhAEV1), from a single isolate of the plant pathogenic oomycete Phytophthora heveae ...
Forestry and wood technology research and education network for climate change adaptation strategies and ASFORCLIC - HORIZON 2020 project
(Univerza v Ljubljani, 2023)
Seven European universities and research institutions from four countries agreed to collaborate on the ASFORCLIC - HORIZON 2020 project to support the ambitious goals of raising the leading institution's MENDELU research ...
Invasive bark beetle Dryocoetes himalayensis (Coleoptera: Curculionidae: Scolytinae) – A threat for walnut trees (Juglans spp.) in Europe?
(Wiley-Blackwell, 2023)
As walnut trees (Juglans spp.) are of high economic importance, considerable attention has been given to invasive pests of these trees in Europe. In 2016, Dryocoetes himalayensis Strohmeyer, 1908, an alien bark beetle ...
The role of geometry precision in frequency-resonance method for non-destructive wood assessment - numerical case study on sugar maple
(CRC Press/Taylor and Francis Group, 2023)
The application of frequency-resonance method (FRM) for precise log bending testing is limited by complex geometry; usually the cone with variable cross. This case study presents the relationship among non-destructively ...
