Açar, Mikail; Taşar, Neslihan
This study performed statistical analyses based on chromosome micromor-phology of 18 Centaurea taxa, two of which are endemic. ANOVA, Correlation analy-sis, Discriminant analysis and Cluster analysis were performed to determine the relationships between taxa based on chromosomal features. In addition, according to the data obtained from these analyses, the relationships between taxa and sections were tried to be interpreted. As a result of the analyses, the taxa C. drabifolia Sm. floccosa (Boiss.) Wagenitz & Greuter, C. kotschyi (Boiss. & Heldr.) Hayek var. floccosa (Boiss.) Wagenitz and C. behen L. and C. polypodiifolia Boiss pseudobehen (Boiss.) Wagen-itz were located close to each other. These taxa are located in the same sections in the morphological classification. Besides, in the Discriminant analysis, the taxa of Acrocen-tron, Microlophus, Cheirolepis sections were closely located compared to all other taxa. However, results were not seen to cover all taxa of the sections. This study revealed various chromosomal characteristics of some Centaurea taxa distributed in the Eastern Anatolia. It also performed statistical analyses on these data. While determining the relationships between taxa according to chromosomal characteristics, comparing chromosomal formulas and indices collectively and evaluating the relationships was found to be relatively consistent with morphological classification.

Taşar, Neslihan; Tekbudak, İlhan Kaya; Demir, İbrahim; Açar, Mikail; Kürşat, Murat
This study investigated the somatic chromosome numbers and morphomet-ric properties of 11 different taxa belonging to the genus Cuscuta L., which is one of the parasitic flowering plants and causes significant economic losses on agricultural products. For this purpose, the species were examined karyologically and compared statistically. Belonging to the genus Cuscuta, C. campestris Yunck., C. hyalina Roth, C. kotschyana Boiss., C. babylonica Aucher ex Choisy, C. europaea L., C. kurdica Engelm., C. brevistyla A.Braun ex A.Rich, C. planiflora Ten., C. approximata Bab., C. lupuliformis Krock. C. palaestina Boiss. the chromosome number and morphology of the species were investigated using karyological techniques. Chromosome numbers of the species; C. kotschyana, C. babylonica, C. europaea, C. kurdica, C.planiflora 2n=14; C. campes-tris, C. hyalina, C. approximata, C. lupuliformis, and C. palaestina 2n=28 and C. brevi-styla 2n=42 is determined. Also, the species’ chromosome number, total chromosome length, relative length, arm ratio, centromere index and centromere states, and karyo-type asymmetry values were determined. Chromosome numbers of C. kotschyana and C. kurdica taxa were defined for the first time in this study. Thus, new data on the systematics of these species have been revealed.

Genç, Hasan; Yildirim, Bekir; Açar, Mikail; Çetin, Tolga
In this study, a statistical analysis was performed on mitotic metaphase chromosomes of 26 Lathyrus taxa, four of which are endemic. ANOVA, correlation analysis, PCA and cluster analysis were performed to determine the relationships between taxa based on chromosomal criteria. The morphological similarities of plant taxa and chromosomal statistics results may not be always parallel to each other. According to the findings obtained as a result of analysis, the following taxa, which are close to each other were determined: L. hirsutus-L. odoratus, L. brachypterus var. haussknechtii-L. phaselitanus, L. stenophyllus-L. chloranthus, L. gorgoni var. gorgoni-L. nissolia-L. pratensis, L. tuberosus-L. annuus.
