Karyological Investigate of Endemic Species Taraxacum bellidiforme and Taraxacum revertens

Abstract

The chromosome number and morphology on two endemic species of the genus Taraxacum Wiggers. (Asteraceae) (T. bellidiforme Van Soest., T. revertens G.Hagl.) were investigated using karyological techniques. Sample plants were collected from natural habitats in 2013. The basic chromosome number in these species: x= 8 and chromosome numbers were found to be T. bellidiforme 2n=24, T. revertens 2n=24 and 2n=32 in these species. Chromosomes had median point (M), median region (m), submedian (sm) centromers. Satellit were seen some of the chromosomes of these species.

Taraxacum bellidiforme ve Taraxacum revertens Endemik Türlerinin Karyolojik Yönden Araştırılması

Abstract

Taraxacum Wiggers. cinsine (Asteraceae) ait olan endemik iki türün (T. bellidiforme Van Soest., T. revertens G.Hagl. ) kromozom sayısı ve morfolojisi karyolojik teknikler kullanılarak araştırıldı. Bitki örnekleri 2013 yılında doğal habitatlarından toplandı. Çalışılan bu türlerde temel kromozom sayısı x= 8 dir. Türlerin kromozom sayıları; T. bellidiforme 2n=24, T. revertens 2n=24 ve 2n=32 olarak bulundu. Türlere ait kromozomların noktalı median (M), median (m), submedian (sm) sentromerli olduğu gözlendi. Bu türlerin bazı kromozomlarında satellit görüldü.
