Abstract

This study reports on the evaluation of the taxonomical, macro- and micro morphological, anatomical, palynological and cytological features, together with the geographical distribution of Arabis kaynakiae Daşkın (Brassicaceae), a Critically Endangered (CR) species from Turkey. The description of the species was updated following detailed studies on new specimens found in Karaman/Ermenek. The surface microphotographs of seeds and pollen were obtained using Scanning Electron Microscopy. The seed surface ornamentation is papillate and its margins minutely tuberculate. Pollen grains appear tricolpate, isopolar, subprolate in shape, with polar axis of 19.62 ± 0.33 µm and equatorial axis of 12.94 ± 0.17 µm. The exine thickness ranges from 1.68 to 1.87 µm; however, the intine thickness ranges from 0.21 to 0.39 µm. Arabis kaynakiae has pollen of coarse reticulate type surface ornamentation with slightly undulated muri. Anatomical characters of root, stem and leaf of the species were also given. The cytological investigations revealed that A. kaynakiae is diploid with 2n = 2x = 16 chromosomes. The discovered population of A. kaynakiae increased the known distribution range of the species in Turkey, and an updated evaluation of the species considering the IUCN criteria was provided.

Özet

Bu çalışma, Türkiye'den kritik olarak tehlike altındaki endemik (CR) bir tür Arabis kaynakiae Daşkın'ın (Brassicaceae) taksonomik, makro ve mikro morfolojik, anatomik, palinolojik ve sitolojik özelliklerinin coğrafi dağılımıyla birlikte değerlendirilmesini rapor etmektedir. Türün deskripsiyonu Karaman/Ermenek'te bulunan yeni örnekler üzerinde yapılan detaylı çalışmaların ardından güncellenmiştir. Tohum ve polenlerin yüzey mikrofotoğrafları Taramalı Elektron Mikroskobu kullanılarak elde edilmiştir. Tohum yüzey ornamentasyonu papillattır ve kenarları az çok tuberkulattır. Polen taneleri trikolpattırlar, 19,62 ± 0,33 µm polar ekseni ve 12,94 ± 0,17 µm ekvator ekseni ile izopolar ve subprolat şeklindedirler. Eksinin kalınlığı 1,68 ila 1,87 µm arasında değişmiş; buna karşın, intin kalınlığı 0,21 ila 0,39 µm arasında değişmiştir. Arabis kaynakiae hafif dalgalı muri ile kaba ağsı tip yüzey ornamentasyonuna sahiptir. Türün kök, gövde ve yaprak anatomik karakterleri de verilmiştir. Sitolojik araştırmalar A. kaynakiae’nin 2n = 2x = 16 kromozomlu diploit olduğunu ortaya koymuştur. A. kaynakiae’nin Keşfedilen popülasyonu, Türkiye'de türün bilinen dağılım aralığını artırmış ve türün IUCN kriterleri dikkate alınarak güncellenmiş bir değerlendirmesi sağlanmıştır.
