The Cross-section Variations in Red Pine (Pinus brutia Ten.) Needles as an Indicator of Atmospheric Pollution: Gökova Thermal Power Plants

Abstract

In this study, the anatomical and morphological anomalies on the cross-section of calabrian pine needles (Pinus brutia Ten.) caused by air pollutants emitted from the Kemerköy (Gökova) Thermal Power Plant (KTPP) were investigated with fieldworks and microscopic techniques.

 

At the end of the land researches, it was found out that air pollutants such as sulfur dioxide, nitrogen oxides and fly ash had caused serious injury, so that 3 year-old-needles fell very early.

 

On the microscopic observation on the cross-sections of the needles, it was determined that the diameter of the main and especially subordinate resin canal dilated too and the number of resin canals increased. It was also observed that the endodermis layer in transmission corymbs and the cells in transfusion texture had become thin, and the intra-cellular material had disappeared owing to air pollutants.

THE CROSS-SECTION VARIATIONS IN TURKISH PINE (Pinus brutia TEN.) NEEDLES AS AN INDICATOR OF ATMOSPHERIC POLLUTION: GÖKOVA THERMAL POWER PLANTS

Abstract

Bu çalışmada Kemerköy (Gökova) Termik Santrali’nin (KTS) oluşturduğu hava kirleticilerin kızılçam iğne yaprak enkesitlerinde oluşturduğu anatomik ve morfolojik anomalilerin arazide ve mikroskobik çalışmalarla ortaya konulması hedeflenmiştir. Arazi çalışmaları sonucunda kükürt dioksit, azotoksit ve uçucu küllerin ibrelerde ciddi zararlar yarattığı ve 3 yaşındaki ibrelerin çok hızlı bir şekilde dökülmesine neden olduğu gözlemlenmiştir. Mikroskobik olarak yapılan gözlemlerde ise ana ve özellikle tali reçine kanallarında genişleme olduğu ve reçine kanalı sayısının arttığı tespit edilmiştir. İletim demetlerindeki endodermis tabakasında ve iletim demetlerinde incelmelerin meydana geldiği ve hücre içi dokuların kirlilikten ötürü zarar gördüğü gözlemlenmiştir
