Abstract
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.
