The present study describes approaches for the identification of individual beech trees using maternal tissues from their seeds or fruits. Four microsatellite markers were used for genetic analysis of seedlots from Fagus orientalis Lipsky, a highly out-crossing tree species. Seeds from 11 single-tree harvests belonging to one population, (7 seeds from each), as well as non-paranchymatic materna...

In this study which has been conducted in Akçasu Forest Range District of Devrek Forest Directorate; 3 methods (weed control with labourer power, cover removal with Hitachi F20 Excavator, and weed control with agricultural equipment mounted on a Ferguson 240S agriculture tractor) were utilized in weed control efforts in regeneration of degraded oriental beech forests have been compared. In this...

Reforestation with autochthonous species should take into account the preservation of the temporal variability and the geographic structure of genetic diversity in forest species. In order to provide empirical data about the suitability of methods of sampling material, genetic comparison of 10 beech populations (at least 40 trees per population) and their progenies (seeds of 10 mother trees per...

Surface roughness and discoloration of thermally modified Scots pine (Pinus sylvestris L.), Kazdağı fir (Abies equi-trojani Asch. et Sint.), Eastern beech (Fagus orientalis Lipsky) were evaluated. The surface the samples sanded with 60, 80, 120-grit grades evaluated at temperature levels 160, 180, 200, 220 °C. Findings subjected to multiple analysis variance Duncan’s homogeneity tests; using SP...

Bu çalışmada, tahribatsız test yöntemlerinden birisi olan stres dalga yöntemi kullanılarak belirlenen dinamik elastikiyet modülü ile TS ISO 13061-2 (2021) standardına göre statik arasındaki ilişkiyi incelenmiştir. kapsamda rastgele seçilmiş 12x13x110 cm3 boyutlarındaki kayın (Fagus orientalis Lipsky) keresteler kullanılmıştır. Kerestelerin radyal ve boyuna yöndeki uçuş süreleri, 1 μs hassasiyet...

the present research was performed in patom, namkhaneh, gorazbon, chelir and baharbon districts in kheyrud forest. due to existence of forest typology map and extension of study area, this study was confined to beech dominated forests. a stratified sampling method based on landform is used to locate 1000 m2 circular sample plots. the number of fagus orientalis lipsky trees ? 7.5 cm in dbh withi...

Bu çalışmada ülkemizde ticari önemi olan ağaç türleri odunların da mikrodalga işlemi ile verniklerin parlaklık özellikleri üzerine etkileri araştırılmıştır. Odun yüzey işlem maddeleri arasındaki etkileşimin belirlenmesi, odun özelliklerinin iyileştirilmesi ve farklı kullanım yerleri için uygunluklarının belirlenerek ortaya konulması oldukça önemlidir. amaçla 3 türü; yapraklı türlerinden doğu ka...

In this research, the effect of wood species and particle size on mechanicalproperties of wood plastic composites (WPC) made of fir (Abies alba) and beech(Fagus orientalis L.) sawdust and high density polyethylene (HDPE) wereinvestigated. Wood plastic composite (WPC) were made with 30% HDPE in abatch process at 185˚C, at two particle sizes of 40 mesh and 80 mesh. Maleicanhydride polypropylene (...
