composition and structure of a three-storied fagus orientalis-dominated forest was investigated in the caspian forests, north of iran. circular sampling plots of 1000 m2 occupied by advance growth and natural regeneration were randomly chosen where the initial cuttings (with shelterwood aim) were performed. abundance of species at different growth stages and quality of seedlings and saplings we...

resource sustainability requires a thorough understanding of the influence of forest management programs on the conservation of genetic diversity in tree populations. to observe how differences in forest management affect the genetic structure of fagus orientalis lipsky (oriental beech), we evaluated thirteen beech sites across hyrcanian forests, based on six microsatellite loci. significant di...

This study is carried out in order to increase the retention performance of synthetic boron compounds. For this purpose, test samples prepared from Scots pine (Pinus sylvestris Lipsky), European oak (Quercus petraea Liebl.) and Oriental Beech (Fagus orientalis Lipsky) woods impregnated with dipping method accordance principles TS 6193 EN 84 by using 12 different composisiton Developed Impregnat...

In this study, the differences in terms of fiber morphology and chemical composition between heartwood sapwood red gum (Eucalyptus camaldulensis Dehnh.), black willow (Salix nigra Marsh.), oriental beech (Fagus orientalis Lipsky) were investigated. The results showed that samples had shorter fibers lower slenderness ratios than those samples. vessel element length sampled tree species statistic...

this study aims at analyzing spatial pattern and associations of fagus oriantalis lipsky in different vertical classes in intact beech forests. data collection was done in 25 ha plot in gorazbon district of educational and experimental forests of university of tehran. species and dbh of all trees with dbh > 7.5 cm were recorded. the location of each tree was determined using azimuth and distanc...
