Abstract

This study performed statistical analyses based on chromosome micromorphology of 18 Centaurea taxa, two of which are endemic. ANOVA, Correlation analysis, 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.) Wagenitz 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 Acrocentron, 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.

分布在土耳其东安纳托利亚的半人马属植物(centaurrea L.)分类群染色体特征的统计综述

本研究对18个半人马属植物分类群的染色体微形态进行了统计分析，其中2个是地方性的。采用方差分析(ANOVA)、相关分析(Correlation analysis)、判别分析(Discriminant analysis)和聚类分析(Cluster analysis)等方法，根据染色体特征确定类群间的关系。此外，根据这些分析得到的数据，试图解释分类群和剖面之间的关系。分析结果表明，黄花楸属植物的分类群为黄花楸属。floccosa木香。瓦格尼茨和格鲁特，C. kotschyi。& Heldr)。Hayek变种絮状(Boiss)Wagenitz和C. behen L.和C. polypodiifolia Boiss pseudobehen (Boiss.)瓦格尼茨号彼此挨得很近。这些分类群在形态分类上位于同一剖面。此外，在判别分析中，Acrocentron、Microlophus、Cheirolepis的剖面与其他类群的定位较为接近。然而，结果并未覆盖所有剖面的分类群。本研究揭示了分布在安纳托利亚东部的半人马属植物的各种染色体特征。并对这些数据进行了统计分析。在根据染色体特征确定类群间的关系时，对染色体公式和指标进行集体比较，评价其关系，发现与形态分类比较一致。

期刊介绍： Caryologia is devoted to the publication of original papers, and occasionally of reviews, about plant, animal and human karyological, cytological, cytogenetic, embryological and ultrastructural studies. Articles about the structure, the organization and the biological events relating to DNA and chromatin organization in eukaryotic cells are considered. Caryologia has a strong tradition in plant and animal cytosystematics and in cytotoxicology. Bioinformatics articles may be considered, but only if they have an emphasis on the relationship between the nucleus and cytoplasm and/or the structural organization of the eukaryotic cell.
