Karyological investigation of four endemic hyacinthella Schur species distributed in Turkey

In this thesis study, four endemic species of the Hyacinthella genus (Hyacinthella acutiloba, Hyacinthella campanulata, Hyacinthella micrantha and Hyacinthella siirtensis), belonging to the Asparagaceae family of monocot plants, were examined karyologically. Root tips obtained by germinating the bulbs of these four species collected for cytotaxonomic studies were used. As a result of the examinations carried out on dividing somatic cells, chromosome counts of the species were made, karyotype analyzes were performed and ideograms were drawn. It was determined that the chromosome numbers of the species were 2n=18 in Hyacinthella acutiloba, 2n=18 in Hyacinthella campanulata, 2n=22 in Hyacinthella micrantha and 2n=22 in Hyacinthella siirtensis.
