Abstract

We conducted the present study on seven important medicinal species of Achillea (in a total of 28 populations) in their natural habitats. The results indicated that the populations had a base number (x= 9) and the diploid, tetraploid, and hexaploidy levels were observed. In addition to the inter-species diversity, there was the intra-species genetic diversity as A. millefolium (4x, 6x), A. vermicularis (2x, 4x), A. tenuifolia (2x, 4x), A. Aleppica (2x), A. talagonica (2x), A. biebersteinii, and A. wilhelmsii (4x). Furthermore, studies also indicated that 11 out of 28 populations had 1A symmetry, 15 populations had 2B symmetry, a population had 2A, and another population had 2B. Cluster analysis of cytogenetic variables could differentiate only the species of A. aleppica, A. talagonica and A. wilhelmsii but others could not separate differences between species appropriately, probably due to the superiority of intra-species diversity of populations to inter-species diversity. Furthermore, we found %TF and DRL are useful parameters for differentiating intrachromosomal variation of species.

标题伊朗库尔德斯坦7种阿基米德属植物的核形态比较

本文对7种重要药用植物阿基那(Achillea)的28个居群进行了研究。结果表明，该群体具有基数(x= 9)，具有二倍体、四倍体和六倍体水平。除种间多样性外，种内遗传多样性主要表现为:千叶麻(4x, 6x)、蛭形麻(2x, 4x)、细叶麻(2x, 4x)、阿勒皮麻(2x)、塔拉根麻(2x)、比伯斯泰尼麻和威廉麻(4x)。此外，研究还表明，28个种群中有11个具有1A对称性，15个种群具有2B对称性，一个种群具有2A对称性，另一个种群具有2B对称性。细胞遗传变量的聚类分析仅能区分阿勒皮、塔拉冈和威廉姆三种，而其他的聚类分析不能很好地区分种间差异，这可能是由于种群的种内多样性优于种间多样性。此外，我们发现%TF和DRL是区分物种染色体内变异的有用参数。

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.
