“…Among these parameters, there are seven different quantitative indices. The TF%, Syi and Rec values decrease with increasing asymmetry and the As K%, the A1-A2 and the A values increase with increasing asymmetry (Zuo and Yuan 2011). According to the As K%, TF% and Syi indices, L. peltata has the most symmetrical karyotype.…”

which is represented by three taxa growing naturally in Turkey, were studied. The somatic chromosome numbers observed in each taxa was 2n=14. The classification of chromosomes, the length of long and short arms, haploid chromosome length, arm ratio, centromeric index and relative chromosomal length were measured by Software Image Analyses (Bs200Pro). Also their karyotype asymmetry indices (TF%, As K%, Syi, Rec, A, A1 and A2) were calculated. According to the asymmetry index, L. peltata has a more symmetrical karyotype than L. canescens. This is the first study for account of chromosome counts and karyotypes for the studied taxa.

“…Preparations were examined using an Olympus BX53 light microscope equipped with a digital camera. Moreover, measurements of somatic chromosomes were taken by CAMERAM software; they were calculated with a formula of the relative variation in chromosome length (CV CL ) and mean centromeric asymmetry (M CA ) (Zuo and Yuan, 2011;Peruzzi and Eroğlu, 2013). The classification of chromosomes as having metacentric (m), submetacentric (sm), subtelocentric (st), and telocentric (t) centromeres was used, according to Levan et al (1964).…”

“…Thus, we used other indices to determine the most symmetrical or asymmetrical karyotype. The TF% and Syi-Rec values decrease with increasing asymmetry, while the As K %, the A1-A2, and the A values increase with increasing asymmetry (Zuo and Yuan, 2011;Eroğlu et al, 2013). When we compare S. violacea and S. ahmetduranii based on these indices, S. ahmet-duranii has the most symmetrical karyotype and S. sericea has the most asymmetrical karyotype in subgenus Scorzonera.…”

In the present study, chromosome morphology of 32 Scorzonera L. taxa, including 19 species endemic to Turkey, was analyzed. The plant materials were collected from different natural populations of Turkey between 2005 and 2011. The classification of chromosomes, the length of the long and short arm, haploid chromosome length, arm ratio, and relative chromosomal length were measured by software image analyses. The basic chromosome numbers were determined as x = 6 and x = 7. Two types of ploidy levels were observed as diploidy and tetraploidy. Karyotype asymmetry indices, TF%, As K%, Syi, Rec, A, A1, and A2 were also calculated.
