Bu araştırmada Arbutus unedo'nun farklı orman
habitatlarındaki yaprak özellikleri karşılaştırıldı., Spesifik yaprak alanı ve spesifik
yaprak ağılrığı yaprak karakterleridir. Bu karakterler ekosistem dinamiği için
çok önemli yaprak özellikleridir. SLA ve LMA, çevreye karşı verilen tepkide ve
bitki fonksiyonları üzerindeki etkilerde (örneğin; yaprak besinleri ve ekonomisi,
atmosfer ile gaz alışverişi vb.) önemlidir. A.
unedo, doğal olarak Avrupa-Sibirya floristik bölgesinde yetişen bir Akdeniz
enklav türüdür. A. unedo'nun yaprak
özellikleri doğal ve P. pinaster
ekili ormanlarda incelenmiştir. Vejetasyon dönemi boyunca ormanlardan yaprak
örnekleri toplandı ve SLA ve LMA değerleri hesaplandı. Doğal ormandaki ortalama
SLA değerlerinin P. pinaster ekili
ormandan yüksek olduğu, P. pinaster
ekili ormanda, LMA değerlerinin doğal ormandan yüksek olduğu bulunmuştur. Fakat
orman habitatları arasında istatistiksel olarak fark bulunmadığı tespit
edilmiştir.

The leaf traits of a Mediterranian species (Arbutus unedo L.) in an undisturbed and planted forests in Euxine Region

Öz

We compared the leaf traits of Arbutus unedo in different forest
habitats in this research. Leaf traits are spesific leaf area and specific leaf
mass. These traits are very important leaf features in ecosystem dynamics. SLA
and LMA response to environment and effect on plant functions (i.e. leaf
nutrients and economy, gas exchanges with atmosphere and etc.). A. unedo is a mediterranian enclave
species, naturally growing in Euro-Siberian floristic region. Leaf traits of A. unedo were investigated on a natural
and P.pinaster planted forest. We
collected leaves during vegetation period from forests and calculated SLA and
LMA values. We found that mean SLA values in natural forest are high than the P. pinaster planted forest and LMA
values in P. pinaster planted forest
are high than the natural forest. But statistical differences were not found
between forest habitats.
