Karyotype Analysis Of Some Taxa Of Dianthus Section Verruculosi (Caryophyllaceae, Sileneae), Derya Altay, Hali̇l Erhan Eroğlu, Ergi̇n Hamzaoğlu, Murat Koç
Turkish Journal of Botany
The purpose of this study was to determine chromosome numbers and karyological features of six Dianthus taxa belonging to section Verruculosi from Anatolia, Turkey. The chromosome numbers were determined as 2n = 30 in all taxa. Karyological measurements were made in detail for the first time for all taxa. Chromosome counts were given for the first time for all taxa except D. cyri and D. strictus. A new chromosome number was determined for D. strictus. The intrachromosomal and interchromosomal karyotype asymmetries were estimated with MCA and CVCL values.

Turkish Journal of Botany
Forty wild populations belonging to five Asparagus species including the endemic A. altissimus were sampled in an east-west bioclimatic gradient of North Algeria. More than 250 individuals were taxonomically examined and karyologically investigated. Meiotic behavior was analyzed for each species. New chromosome numbers were consistent with the base number x = 10 for the genus Asparagus, and two cytotypes, diploid and hexaploid, were observed. Four species were found to have 2n = 20 chromosomes, highlighting the prominence of diploidy in North Africa. One polyploid with 2n = 60 is reported here as the first karyological information on the endemic A. …
