Generalized height-diameter models for Picea orientalis L.
The purpose of this paper is to compare major models for height estimation of Picea orientalis L trees based on the individual tree diameter and certain other stand variables. The data were collected from 440 trees of pure and even-aged P. orientalis stands that are located near Artvin in the northeastern part of Turkey. The data from 406 trees were used for model development and the remaining ...
متن کاملClassifying Oriental Beech (Fagus orientalis Lipsky.) Forest Sites Using Direct, Indirect and Remote Sensing Methods: A Case Study from Turkey
Determining the productivity of forest sites through various classification techniques is important for making appropriate forest management decisions. Forest sites were classified using direct and indirect (site index) and remote sensing (Landsat 7 ETM and Quickbird satellite image) methods. In the direct method, forest site classifications were assigned according to edafic (soil properties), ...
متن کاملMicrosatellite analysis for differentiation and identifica- tion of the source tree of Fagus orientalis Lipsky
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...
متن کاملThe Efficiency of Mechanization in Weed Control in Artificial Regeneration of Oriental Beech (Fagus orientalis Lipsky.)
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...
متن کاملRemoval of Lead from Aqueous Solutions using Fagus orientalis Lipsky: Box-Behnken Experimental Design
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...
