Abstract

Çalışmanın amacı: Bu çalışmanın amacı Sarıçamın kozalak ve tohum morfolojik özelliklerinin çeşitli doğal popülasyonlarda incelenmesidir.
Çalışma alanı: Bu çalışma Türkiye'nin Batı Karadeniz Bölgesinde yer alan 12 farklı doğal Sarıçam popülasyonlarında gerçekleştirilmiştir.
Materyal ve yöntem: Toplamda 12 farklı popülasyondan 600 kozalak ve 1727 tohum örneği elde edilmiştir. Popülasyonlar arasında kozalak ve tohum özelliklerindeki (kozalak boyu, kozalak çapı, tohum uzunluğu, tohum genişliği, tohum kanat uzunluğu, tohum kanat genişliği ve bu karakterlerin en/boy oranları) farklılıkları araştırmak için Çok Değişkenli Varyans Analizi ve post-hoc testi kullanılmıştır.
Temel sonuçlar: Sarıçam bireylerinin kozalak ve tohum morfolojik karakterleri popülasyonlar arasında istatistiksel olarak anlamlı farklılıklara sahip bulunmuştur. Hem çap hem de boy olarak en büyük kozalaklar Dedemdağ (Tosya) popülasyonunda bulunmuştur. Bunun yanında, en küçük kozalaklar Kızılkaya (Yenice) ve Kartalkaya (Aladağ) popülasyonlarından elde edilmiştir.
Araştırma vurguları: Doğal sarıçam popülasyonlarının korunması özellikle tohum kaynaklarının muhafazası için oldukça önemlidir. Bu çalışma Batı Karadeniz bölgesindeki potansiyel sarıçam populasyonları hakkında önemli bilgiler sağlamaktadır.

Investigation of The Morphological Characteristics of Cones and Seeds of The Scots pine (Pinus sylvestris L.) in Natural Populations in Northwestern Türkiye

Abstract

Aim of study: The aim of this study is to investigate the morphological characteristics of Scots pine cones and seeds in a variety of natural populations.
Area of study: The study was carried out in 12 different natural Scots pine populations in the Western Black Sea Region of Türkiye.
Material and method: A total of 600 cone and 1727 seed samples were collected from 12 natural Scots pine populations. Multivariate Analysis of Variance and post-hoc test were used to investigate differences in cone and seed characteristics including cone length (cl), cone diameter (cd), cl/cd ratio, seed length (sl), seed width (sw), sl/sw ratio, seed wing length (wl), seed wing width (ww) and wl/ww between populations.
Main results: Cone and seed morphological characteristics of Scots pine individuals showed statistically significant differences between populations. The Dedemdağ (Tosya) population had the largest cones in terms of both diameter and length, while the Kızılkaya (Yenice) and Kartalkaya (Aladağ) populations had the smallest cones.
Research highlights: The protection of natural populations of Scots pine is very important, especially for the conservation of seed resources. This study provides important information about potential Scots pine populations in Northwestern Türkiye.
