Abstract

An evaluation was conducted of A. yamadagensis, which is a Critically Endangered (CR) species that is endemic to Turkey, comprising an analysis of its taxonomical, micromorphological, macromorphological, cytological and palynological features, in addition to its geographical distribution. Scanning Electron Microscopy was used to obtain seed and pollen surface microphotographs. The shape and sculpturing of the seed periclinal walls are convex and granulose. The shape of the pollen grains appears monocolpate, with polar and equatorial axes of 23.65 ± 0.29 and 14.92 ± 0.33 µm, respectively. A. yamadagensis has a pollen ornamentation that is foveolate-microreticulate. Cytological analyses revealed that A. yamadagensis is diploid and has a chromosome number of 2n = 2x = 16.

Özet

Bu çalışma, Türkiye'den Kritik Tehlike Altındaki (CR) bir endemic tür olan A. yamadagensis'in coğrafi dağılımı ile birlikte taksonomik, makro ve mikro morfolojik, palinolojik ve sitolojik özelliklerin değerlendirilmesini rapor etmektedir. Tohumların ve polenin yüzey mikro fotoğrafları Taramalı Elektron Mikroskobu kullanılarak elde edildi. Tohum periklinal duvarları (şekil ve yontma) dışbükey ve granül. Polen taneleri, 23.65 ± 0.29 μm kutup eksenleri ve 14.92 ± 0.33 μm ekvator eksenleri ile tek kolpat şeklinde görünür. A. yamadagensis'in polen süslemesi foveolat-mikroretikülattır. Sitolojik araştırmalar, A. yamadagensis'in 2n = 2x = 16 kromozomlu diploid olduğunu ortaya çıkarmıştır.
