Meticulous chemical analysis of decaying xylem and linking it to corresponding anatomical modification at the cellular level can improve our understanding decay process. The aim this study was monitor histological, chemical, photochemical, progression wood degradation by two white-rot fungi different intervals. Oriental beech (Fagus orientalis) blocks were exposed Pleurotus ostreatus Trametes versicolor investigate capabilities these fungi. Light microscopy used patterns in wood. Decayed...
The impacts of white-rot fungi on altering wood chemistry have been studied mostly in vitro. However, vivo approaches may enable better assessment the nature interactions between saprotrophic and host tree nature. Hence, decayed sound samples were collected from a naturally infected (Carpinus betulus L.). Fruiting bodies white rot fungus Trametes versicolor grown same identified using rDNA ITS sequencing. Chemical compositions (cellulose lignin) both studied. FT-IR spectroscopy was used to...
Summary Chemical, light and electron microscopic studies were carried out on wood of Oriental beech ( Fagus orientalis Lipsky) decayed by the white‐rot fungi Pleurotus ostreatus Trametes versicolor for 30, 60 120 days according to modified European standard EN 113. Mass loss as well lignin, cellulose carbohydrate content determined before after fungal attack. There no significant differences mass chemical composition between both at end incubation. After each incubation period, small...
Summary In this research, we examined decay patterns occurring in Quercus castaneifolia wood under natural conditions compared with controlled vivo . Pleurotus ostreatus ‐infected oak was obtained from the Sari forests north of Iran. The species causing verified as P. using rDNA ‐ ITS sequencing pure cultures infected sapwood. addition to , two wood‐inhabiting Ascomycota, Trichoderma harzianum and T. lixii, were present. Mass loss sapwood samples exposed for 60 days around 10 per cent....
As to the importance of permeability in preservation process solid woods, effects diffusion drying schedule with three different initial moisture contents (MC) on fluid flow sapwood and heartwood paulownia wood (Paulownia fortunei) were studied here.Boards MCs 113 % (D-1), 75.5 (D-2) 53.5 (D-3) dried final content 8 ± 2 %.Results showed a significant difference specific gas liquid these MCs.Although specimens was significantly different, no seen between two parts.D-2 D-1 highest...
Weekly rate of Beech tree ring increment were related to the changes climatic factors in weekly intervals. In order do so, small samples extracted from 5 Oriental beech trees located Nowshahr educational forest central part Hyrcanian forests Iran during 2008 growing season. Microscopic sections prepared and average increases width measured, standardized modeled using Gompertz equation. The results showed that minimum air temperature water evaporation had strongest positive effect on...
Abstract The use of pyrolysis acid (PA) as a liquid by‐product the slow wood or any other lignocellulosic biomass has been widely developed in agriculture for variety purposes such crop enhancement pesticide. Evidence from literature suggests that PA could be used sustainable preservative to protect against rot fungi and termites. experimental work presented here provides one first investigations into anti‐decay efficiency PA. Crude acquired three different types at two temperature ranges...
One strategy for improving the treatability of refractory wood species is biological incising, and its efficiency depends on how microorganisms modify porous structure wood. Evaluation bioincised a micro-scale can thus help to better understand enhancing mechanisms. In present study, biodegradation pattern Loblolly pine (Pinus taeda L.) heartwood were determined after bioincising with white-rot fungus Physisporinus vitreus (Pers.: Fr.) P. Karsten isolate 136 bacterium Bacillus subtilis...
