Özet:

 Aim of the study: This study was undertaken to determine the effect of elevation on the characteristics of cones and seeds of black alder Alnus glutinosa subsp. barbata. Area of study: Cones were collected from three different elevations 270 m, 590 m and 860 m within the native range of the species in in Arhavi district of Artvin Province, in October 2017. Material and methods: Morphological characteristic such as diameter and length of cones, width, length and thickness of seeds were measured. In addition, germination percentage and mean germination time parameters were used to evaluate the germination ability of seeds. Germination experiments were carried out with four replications where each replicate contained 50 seeds. Stratification pre-treatment was applied to seeds for 2, 4, 6 and 8 weeks. Main results: Results showed that cone diameter, seed length, seed width and seed thickness were significantly affected by elevation. Differences in germination percentage and average germination time also were significant p0.05 with respect to elevation. Seeds collected from 270, 590 and 870 m had the 2.71, 2.63 and 2.61 mm, seed lengths, 2.45, 2.49 and 2.08 mm seed width and 0.49, 0.52 and 0.41 mm seed thickness, respectively. Research highlights: Seeds collected from 590 m had the greatest germination percentage 63.7.

 Çalışmanın amacı: Bu çalışma, yükseltinin sakallı kızılağaç Alnus glutinosa subsp. barbata kozalakları ve tohumlarının özellikleri üzerindeki etkisini belirlemek amacıyla yapılmıştır. Çalışma alanı: Sakallı kızılağaç kozalakları, Artvin İli Arhavi ilçesindeki türün doğal yayılış alanı içerisindeki üç farklı yükseltiden 270 m, 590 m ve 860 m 2017 yılı ekim ayında toplanmıştır. Materyal ve yöntem: Kozalaklarda, kozalak çapı ve uzunluğu, tohumlarda ise tohum genişliği, uzunluğu ve kalınlığı gibi morfolojik özellikler incelenmiştir. Ayrıca tohumların çimlenme kabiliyetini değerlendirmek için çimlenme yüzdesi ve ortalama çimlenme süresi parametreleri kullanılmıştır. Çimlendirme deneyleri, her tekerrürde 50 tohum olmak üzere dört tekerrürlü olarak gerçekleştirilmiştir. Tohumlara 2, 4, 6 ve 8 hafta katlama ön işlemleri uygulanmıştır. Temel sonuçlar: Sonuçlar, kozalak çapı, tohum uzunluğu, tohum genişliği ve tohum kalınlığının yükseklikten önemli ölçüde etkilendiğini göstermiştir. Çimlenme yüzdesi ve ortalama çimlenme süresindeki farklılıklar da yükseltiye göre önemli bulunmuştur p0.05. 270, 590 ve 870 mden toplanan tohumlar sırasıyla 2.71 mm, 2.63 mm ve 2.61 mm tohum uzunluğuna, 2.45 mm, 2.49 mm ve 2.08 mm tohum genişliğine ve 0.49 mm, 0.52 mm ve 0.41 mm tohum kalınlığına sahiptir. Araştırma vurguları: 590 mden toplanan tohumlar en yüksek çimlenme yüzdesine 63.7 sahiptir.
