The relationships between growth of Pinus sylvestris ssp. hamata forests with ecological factors in Central

Abstract

In this research, relationships in Pinus sylvestris ssp. hamata (Yellow pine) forests spreading over TÜrkmen Mountain (Turkey) were investigated between ecological factors. Although a positive relationship was found between site index and altitude and exposure which are among physiographic habitat factors, a meaningful relationship was not found between exposure and slope position (distance from the top edge of the slope). There was a positive relationship between site index and annual rainfall; however, there was not a meaningful relationship between annual average temperature and main rock. A negative relationship was found between site index and B in the litter and humus layer of the forest floor, and a positive relationship N and P in the litter layer was found. The relationship was found site index and Mg and Zn in the needle as positive, it was negative in B. It was determined that there were meaningful statistical relationships between site index and variables of soil horizons. When physiographic habitat factors were evaluated with climatic characteristics and litter characteristics, percentage values of soil horizons variables on the total effect of Yellow pine's maximum height growth was 47.6% in joining grade.
