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 the impact of production work on the skid roads that have been carried out for many years by manpower animal power or machinery in a beech (Fagus orientalis Lipsky) stand have been examined. For this purpose, herbaceous understory, forest floor and soil samples were collected from the undisturbed area and the skid road. Weight per unit area (kg ha(-1)), organic matter ratio and mo...
Knowledge of the nutrient content edible seeds oriental beech (Fagus orientalis Lipsky) as a food resource for rural people, is incomplete and there need studies that will provide this information. The collected from 12 different locations in primary distribution area Turkey were investigated their oil fatty acid composition. contents these populations determined by gas chromatography-mass spec...
The effects of soil pedoturbation (i.e., pit and mound microtopography, PM) on development of herbaceous plant species and woody species regeneration were examined in a temperate beech forest (Fagus orientalis Lipsky) in northern Iran. We recorded the vegetation in 20 pairs of disturbed and adjacent undisturbed plots and established a chronosequence of PM ages to study the effect of time since ...
The aim of this study was to investigate the effects of thermally compressed veneer laminating on some of the physical and mechanical properties of particleboard. Oriental beech (Fagus orientalis Lipsky) veneers were compressed under various press conditions. Commercially produced particleboard samples were laminated with such compressed veneer sheets. The density, 2-h and 24-h water absorption...
The goal is to protect semi-finished/finished wood components from burning/fires in a variety of settings (wooden buildings, historical sites, restoration, etc.). Natural (organic) sea mussel shells (Chamelea gallina) were crushed and prepared with water various solution concentrations (10%, 15%) after the pyrolysis process, either alone or together boron compounds (borax). limiting oxygen inde...
In this study, investigation of the combustion properties Oriental beech wood (Fagus orientalis Lipsky) impregnated with boron compound (borax (Na2B4O710H2O), boric acid (H3BO3) doped rosin (C19H29COOH) was aimed. For purpose, samples were prepared according to ASTM E 160-50 and by method medium-term dipping (24 hours) D 1413 producers’ definition. Combustion after process determined 160-50. As...
