  Background and Objective: The study growth performance of afforestation and adaptation species planting in the new region increasing succes the future afforestation. The aim of this study is growth performance of Pinus brutia Ten in the plantation stand (ca. 41 ha and 2×3 m spacing) located in the north part of the khoramabad city.Method: For this purpose, 5 pine trees were randomly selected and cut. current annual increment volume obtained by trunk analysis. 35 samples were taken from Pinus Brutia trees at breast height by increment borer for closer examination. in the study area and according to regression analysis, the annual volume increment of these 35 samples were obtained and finally the data of annual increment were extracted from 40 Pinus Brutia trees.Findings: Results showed in comparison to Pinus Bruttia afforestation of origin (Turkey), Annual growth volume in hectare less growth Volume and Average growth volume and Dominant Height (DH) more. Generally, region located between good and medium site conditions. Also in the study Mean annual increment Pinus Brutia befor 30 years is 11.95 m3/ha.Discussion and Conclusion: This growth performance showes fast growing and adaptation species to ecological conditions region. Therefore, regions with same ecological conditions can be considered as suitable sites for, pinus brutia plantation for the industrial wood production and paper industry suppliers to avoid excessive outflow of currency from the country.  Manuscript profile

  Background and Objective: Afforestation stand of Ghapan region (with 232 ha-1 area) was selected for investigation of quantitative and qualitative characteristics of Pinus brutia ten. Method: Three altitude classes (200-400, 400-600 and 600-800m) were classified and&nbs More

  Background and Objective: Afforestation stand of Ghapan region (with 232 ha-1 area) was selected for investigation of quantitative and qualitative characteristics of Pinus brutia ten. Method: Three altitude classes (200-400, 400-600 and 600-800m) were classified and  number of 30 sample plots (with 400m2 area) were selected by using of random – systematically method in every classes. Some of quantitative and qualitative characteristics were recorded in every sample plots. Also, three soil profiles (A and B horizons) were excavated in every three altitude classes for investigation of soil properties. Findings: Results of this research showed that mean D.B.H and height was similar to normal distribution. Volume of high class (600-800m) was estimated more than the other two classes. Qualitative characteristics showed that plummet of stem, stem without branch, fresh of crown were climbing as crown symmetry and stem curvature were reducing with increase of altitude. Multi branch and stem healthy don’t show regular changes in relation to altitude changes. Soil studies showed no significant different in relation with altitude changes. Discussion and Counclusion: The final result shows that pinus brutia ten stands with the best quality and quantity and it is visible in high altitudes.   Manuscript profile
