Managed vs. unmanaged Fagus orientalis Lipsky forests: Structure and diversity of natural regeneration in northern Iran | Pejman Parhizkar, Mohammad Hosein Sadeqzadeh Hallaj, Majid Hassani Agricultural Journals

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...

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...

Effects of drying temperature and artificial UV irradiation on the pH of veneer surfaces, water absorption, thickness swelling, as well as shear strength of plywood manufactured from untreated and treated veneer sheets were evaluated. Rotary cut veneer sheets from beech (Fagus orientalis Lipsky) log were selected. The veneer sheets were dried at either 100C or 180C after peeling. Then the sur...

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...

Fagus orientalis Lipsky tree leaves, which are abundant in Iran, were evaluated for removal of lead from aqueous solutions. The optimization strategy is carried out by using two level full factorial designs. Results of the two levels full factorial design (2) based on an analysis of variance demonstrated that the initial pH, contact time and concentration of biomass are statistically significan...

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...
