Kooch Y, SM Hosseini, Hojjati SM, Fallah A. 2013. Variability of soil physical indicators imposed by beech and hornbeam individual trees in a local scale. Biodiversitas 14: 25-30. The objective of our study was to determine if soil physical indicators could be related to the influence of the individual trees in stands of mixed species growing on steep slopes in the Hyrcanian forests of Iran. Re...

Background and Purpose: Water stress is one of the major problems for urban trees. It affects a wide range of plant responses, from changes at the cellular level to the reduction in growth rates. Irrigation of trees in urban areas may provide numerous benefits important for increasing tree vitality to withstand other stresses that might occur. The aim of this study was to compare drought effect...

Vegetation phenology, as used and studied the related studies, refers to the relationship between climate and periodic development of photosynthetic biomass. selected 15 Hornbeam plots (Carpinus betulus) from study area in a mountainous region from 520m to 1310m above sea level. Ground observations of hornbeam tree growth process from January to December 2004 in 15 day intervals were performed ...

Cement bonded particleboards were manufactured from hornbeam (Carpinus betulus L.) wood particles. Hydration tests were carried out to determine the inhibitory index in order to characterise wood-cement compatibility. The results revealed that the mixture of hornbeam -cement can be classifi ed as moderate inhibition. Two wood: cement ratios were applied in this study, namely 1:3 and 1:4, for th...

chainsaw is an important machine for tree felling limbing and bucking in hyrcanian forest and the major problems related to using forest machines was sound intensity. the aim of this study was to measure the sound level in occupational exposure of workers, determine the exposure time of workers and comparison of the variables among the workers. this study was carried out in namkhaneh district i...

Since the early 2000s, reports on declining hornbeam trees (Carpinus betulus) are spreading in Europe. Two fungi involved decline phenomenon: One is Anthostoma decipiens, but other etiological agent has not been identified yet. We examined morphology, phylogenetic position, and pathogenicity of yellow fungal isolates obtained from Austria, Georgia Switzerland, compared data with disease norther...

The European hornbeam (Carpinus betulus L.) is a transitional species in the Polish flora, reaching its northeastern range limit just beyond the Polish border (Jalas and Suominen, 1976; Boratyńska, 1993). The species is a telocratic taxon which appeared in Central Europe ~5000 years ago and spread throughout Poland ~4000 years ago (Huntley and Birks, 1983; Środoń, 1993; Ralska-Jasiewiczowa et a...

Bu çalışmada, gürgen (Carpinus betulus L.) odunu zımpara tozu ile yüksek yoğunluklu polietilen (YYPE), çift burgulu ekstruderde karıştırıldıktan sonra kompozit malzemeler elde edilmiştir. Elde edilen kompozitlerin mekanik özelliklerini belirlemek için çekme, eğilme ve sertlik direnci testleri yapılmıştır. Bunlara ek olarak, termal Diferansiyel Taramalı Kalorimetre (DSC) analizleri Limit Oksijen...
