Özet

The influence of air pollutants on the architecture of Calabrian pine (Pinus brutia Ten.) needles was examined in polluted and control forest sites around the Yenikoy thermal power plant (YTPP) in Mugla, Turkey. The aim of this research was to test the hypothesis that air pollutants emitted from the YTPP cause the dilation of resin canal diameter on the cross-sections of Calabrian pine needles. For this, the anatomical and morphological anomalies on the cross-sections of Calabrian pine needles were examined It was determined that the air pollutants caused resin canal dilation and epidermis/hypodermis layers slimming on the cross-sections of Calabrian pine needles. It was also observed that the endodermis layer, the transfusion tissue cells had deformed, and the intra-cellular material had disappeared in the inner side of the cells.
