İnterseks Çiçekli Salix caprea L. (Salicaceae)’nın Kuzeydoğu Anadolu’da Varlığı

Çalışmanın amacı: Bu çalışmada, Salix caprea'nın interseks çiçeklere sahip erkek veya dişi kedicikli aynı popülasyondaki dört bireyinin varlığı Türkiye'den ilk kez bildirilmektedir. Çalışma alanı: Gümüşhane (Kuzeydoğu Anadolu)’de sarıçamın baskın olduğu Köse Dağı yol kenarları. Materyal ve yöntem: Çalışma materyalleri, Köse Dağı’ndaki aynı keçi söğüdü popülasyonundan 2017 ve 2018 yıllarında gerçekleştirilen arazi çalışmalarında toplanmıştır. Erkek, dişi ve metamorfoz çiçekli sürgünlerin herbaryum örneklerinden oluşan tüm materyaller önce standart herbaryum tekniğine göre hazırlanmıştır. Temel sonuçlar: Keçi söğüdünün metamorfoz veya interseks çiçeklerden oluşan çiçek kurullarına sahip bireyleri Türkiye’den kaydedilmektedir. Önemli vurgular: Ülkemiz dışındaki kimi söğüt türlerinde metamorfoz çiçekler çok nadir olarak gözlenmektedir. Bu çalışmada ise metamorfoz çiçekli doğal keçi söğüdü bireyleri Türkiye florasına kaydedilmiştir. Bu durumun olası nedenleri çalışma alanındaki dinamikler çerçevesinde tartışılmıştır.

Reporting Intersex Florets in Salix caprea L. (Salicaceae) from NE Anatolia

Aim of the study: In the present paper, male or female catkins composed of several intersexes florets in four individuals (all in the same population) of Salix caprea are reported from Turkey for the first time. Study area: Roadsides at Köse Mountain in Gümüşhane (NE Anatolia) wherein Scots pine forest is dominant. Material and method: Plant materials were collected from the same population belong to goat willow during the excursion around Köse Mountain in 2017 and 2018. All materials consisting male, female and metamorfosans flowered shoots were first processed according to standard herbarium techniques. Main results: Metamorphosans or intersexes florets in Salix caprea were recorded for the first time from Turkey. Research highlights: In extremely rare cases, metamorphosans florets have been reported in several willow species distributed outside of Turkey. However, native goat willow individuals, in which these florets appear, were recorded here for the Turkish flora. Beside its possible reasons were discussed at local scale.
