Abstract:
Research on chromosomes helps to clarify the relationship between taxa. Chromosome number is the simplest parameter that generates valuable information in cytotaxonomic and genome studies of a species. In the plant genome, genetic information includes plant phenotypes, which is why cellular studies are so important.Chromosome number is one of the most important and helpful factors in examining the boundaries of species and genera in plants. In this study, the somatic chromosomal number of 7 species of native plants of Iran was investigated. In this study, Achillea vermicularis (2n=36), Codonocephalum peacockianum (2n=20), Cousinia multiloba (2n=26), Nepeta heliotropifola (2n=36), Pteropyrum aucheri (2n=22), Rumex elbursensis (2n=30), Reaumuria oxiana (2n=22) was reported. Chromosome numbers of Nepeta heliotropofila, Pteropyrum aucheri, Rumex elbursensis, Reaumuria oxiana were reported for the first time. The Chromosome numbers of mitosis of Codonocephalum peacockianum and Cousinia multiloba were reported for the first time. The purpose of this research is to complete the index chromosome of native plants of Iran. Analyses were performed by Micromeasure 3.3 and Excel softwares.
