The morphological and karyological investigation of Artemisia spicigera C. Koch populations that araund the Van Lake

The Morphological and Karyological Investigation of Artemisia Spicigera C. Koch Populations that Araund the Van LakeThis research have been included the morphological and karyological studies on the populations around Van Lake of Artemisia spicigera C. Koch and Artemisia fragrans Willd. that identified as new to Turkey in this research between the 2010-2011 years. The roots, stems, leaves, flowers structures of the plant samples collected from different populations belong to these species were investigated within the framework of morphological studies. The chromosome counts and karyotype analysises of plants collected from different populations of these species were made and idiograms of ones were drawn In the karyological studies. The studied three populations of Artemisia spicigera have the same chromosome numbers that 2n = 18, and the studied ten populations of Artemisia fragrans have different chromosome numbers as nine of them are 2n = 36 and only one of them is 2n = 34 were found. Aneuploidy for Artemisia fragrans was identified.The significant variations of some morphological features in the level of populations of both species were determined. Also, the some new morphological features that are the first record for better recognition of these species were obtained by us.Key Words: Artemisia spicigera, Artemisia fragrans, Caryology, Asteraceae, Morphology
