Study on Growth Performance of Pinus Brutia Ten in the Oldest Plantation Stand of in Khorramabad

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.

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.

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.

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.
