Abstract

This study investigated the somatic chromosome numbers and morphometric 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. campestris, C. hyalina, C. approximata, C. lupuliformis, and C. palaestina 2n=28 and C. brevistyla 2n=42 is determined. Also, the species’ chromosome number, total chromosome length, relative length, arm ratio, centromere index and centromere states, and karyotype 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.

几种土耳其菟丝子(旋花科)的比较核学分析

菟丝子属(Cuscuta L.)是一种对农产品造成重大经济损失的寄生开花植物，对其11个不同类群的体细胞染色体数目和形态特征进行了研究。为此，对这些物种进行了核学检查和统计比较。属于菟丝子属，菟丝子属。， C. hyalina Roth, C. kotschyana Boiss。， C. babylonica Aucher ex Choisy, C. europaea L.， C. kurdica Engelm。A.Braun ex . A.Rich, C. planiflora， C.近似;C. lupuliformis Krock。巴勒斯坦Boiss;利用核生物学技术对该物种的染色体数目和形态进行了研究。物种的染色体数目;C. kotschyana, C. babylonica, C. europaea, C. kurdica, C.planiflora 2n=14;确定了C. campestris、C. hyalina、C. approximata、C. lupuliformis和C. palaestia 2n=28和C. brevistyla 2n=42。测定了该物种的染色体数目、染色体总长度、相对长度、臂比、着丝粒指数和着丝粒状态以及核型不对称值。本研究首次确定了小檗和小檗分类群的染色体数目。由此，揭示了这些物种系统分类学的新数据。

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.
