Abstract

In this study, chromosome number and karyomorphologic features of Onosma sieheana Hayek (Ak emcek in Turkish) which is the endemic taxon for Turkey were investigated for the first time. Performed by squashing method in the root tips with Acetoorcein, the chromosome number were counted 2n=24, and karyotype formula of the taxon were determined to be and 24 m. Basic chromosome numbers of the genus Onosma ranged from 6 to 11. According to this finding, it is thought that the species would be tetraploid (2n=4x=24). Besides with, it is founded that the chromosomes of O. sieheana is symmetric according to the used different karyotype indices in this paper.

Özet

Bu makalede Türkiye için endemik olan Ak emcek (Onosma sieheana Hayek) türünde kromozom sayısı ve karyomorfolojik özellikler ilk kez araştırılmıştır. Kök ucundan ezme yöntemiyle Aseto-orsein kullanılarak gerçekleştirilen bu çalışmada, türün kromozom sayısı 2n = 24, karyotip formülü ise 24 m olarak belirlenmiştir. Önceki çalışmalara göre Onosma cinsinin temel kromozom sayısı x=6-11 arasında değişmektedir. Bu çalışmanın sonuçlarına göre, O. sieheana türünün tetraploid bir tür olduğu düşünülmektedir (2n = 4x = 24). Ayrıca, bu çalışmada kullanılan farklı kromozom indekslerine göre O. sieheana'nın simetrik kromozomlara sahip olduğu belirlenmiştir.
