This study describes the karyotypes of 10 Turkish species of Trigonella L. belonging to section Cylindricae Boiss.(Leguminosae). Excluding the karyotypes of T. velutina Boiss. and of T. sibthorpii Boiss., which were previously studied, all of the other 8 species were studied here for the first time. | Research Article Turk J Bot 34 (2010) 485-494 © TÜBİTAK doi: Karyology of ten Turkish Trigonella L.

(Leguminosae). Excluding the karyotypes of T. velutina Boiss. and of T. sibthorpii Boiss., which were previously studied, all of the other 8 species were studied here for the first time. The species of the section were gathered from different localities in Turkey, and it was determined that the somatic chromosome numbers for all species were the same (2n = 16). Also, satellite metaphase chromosomes were determined in T. velutina and T. strangulata. Key words: Fabaceae, Image Analysis System, karyotype Türkiye’de Cylindricae Boiss. seksiyonundan on Trigonella L. (Leguminosae) türünün karyolojisi Özet: Bu çalışmada, Türkiye’deki Cylindricae Boiss. seksiyonundaki on Trigonella L. (Leguminosae) türünün karyotipi belirlenmiştir. Trigonella velutina Boiss. ve T. sibthorpii Boiss. türleri hariç diğer sekiz tür ilk kez çalışılmıştır. Seksiyona ait türler Türkiye’nin farklı lokalitelerinden toplanmış ve somatik kromozom sayıları bütün türlerde aynı (2n = 16) elde edilmiştir. Ayrıca, T. velutina ve T. strangulata’da satellitli metafaz kromozomları tespit edilmiştir. Anahtar sözcükler: Fabaceae, Görüntü Analiz Sistemi, karyotip Introduction Trigonella L. (Leguminosae) includes about 135 species worldwide, and most of the species are distributed in the dry regions around the Mediterranean, western Asia, Europe, northern .
