for maintaining of zagros forests role in wild life, water and soil conservation, the suitable solutions and methods for assessing the existing conditions and planning for management of this forests should be given. to detection of suitable sampling method to study tree density in the northern zagros forest, blake forest, in baneeh region, kurdistan province, and west of iran was selected. 40 s...

The present study was focused to examine the combined effects of climate and ultraviolet-B radiation on conifer tree-ring density. Statistical methods were employed to extract tree responses in annual ring density and to identify functional relationship in trees when the level of ultraviolet-B radiation changes regardless of climate variations. In this study, the consideration was given to the ...

In order to evaluate the possible correlation between the tree density and the human population density, the forested area in Nav Asalem district located in Guilan Province was selected. The descriptors of tree number and basal area per hectare as well as the stand density index were used to determine the tree density, which was conducted from a 2014 forest inventory including 62 cluster (558 p...

high-density planting system is one of the effective methods for improving production and profitability of tree orchards. in this research, the effects of four planting densities (1904, 2666, 3137 and 4800 tree/ha) on annual shoot growth, tree yield, physicochemical properties of fruit and leaf mineral contents of apple (malus domestica borkh cv ‘granny smith’treegrafted on m26 clonal rootstock...
