Özet:

This study, the coastal tree in Turkey (Pinus pinaster Ait.) The trees are made in order to determine the carbon levels of the tree components, the weight carbon levels of the surface and the total mass of the tree and the relationship between the weight carbon levels and the characteristics of the cultivation environment. Examples were made in a total of 69 areas in the tree age, showing differences in terms of the characteristics of the growing environment and the development of the cattle. The environmental characteristics of the sample fields are determined. Then, in each sample area, a tree in the upper height of the shell was cut and from the cut tree were taken samples of ibre, branch, wood, cortex and root. Carbon analyses were performed in plant samples taken from sample fields in the laboratory. The data obtained was evaluated through variance analysis, Duncan test and correlation analysis. There have been significant differences between the carbon levels of the tree components (P<0,001). The carbon intensity was found at the lowest root (48.8%) and the highest in the cortex (53.9%. The weight of carbon for coastal strawing is estimated to be 51.9 per cent for the mass of the ground tree and 51.4 per cent for the total mass of the tree. There have been significant differences between the geographical areas (Marmara and the Black Sea) in terms of the weight of carbon of the total tree mass (P<0,05).

Özet:

The aim of this study was to determine the carbon concentration of various components of maritime pine (Pinus pinaster Ait.) plantations in Turkey, as well as the weighted carbon concentration of above-ground and total tree biomass, and to examine site-related differences in weighted carbon concentration. Samples were collected from 69 sampling plots at a mature stage with different site characteristics and stand growth, and site characteristics of the sample plots were determined. Then, an individual tree representing the top height in each sampling plot was cut, and needle, branch, wood, bark, and root samples were collected from the these trees. Carbon analysis on plant samples collected from the sampling plots was carried out in the laboratory. The data were evaluated by using variance analysis (ANOVA), Duncan’s test, and correlation analyses. Statistically significant (at P<0.001) differences were found between carbon concentrations of tree components. The lowest carbon concentration was in roots (48.8%), while the highest carbon concentration was in barks (53.9%). The weighted carbon concentration of maritime pine plantations was found to be 51.9% for the above-ground biomass while it was 51.4% for the total tree biomass. Statistically significant (at P<0.05) differences by weighted carbon concentrations of total tree biomass were also found between the Marmara and the Black Sea Regions.
