Abstract

The present study is reported somatic chromosome number of two Tanacetum speciesincluding T. stapfianum (Rech.f.) podlech (2 population)and T. lingulatum (Boiss.) Bornm. (1 population) for the first time. They belong to Asteraceae family and are endemic species from Iran. Two species of Tanacetum were collected from their habitats to investigate their karyotypes. Both species were diploid and chromosome numbers were 2n=2x=18. Ideograms are depicted for each population.

Abstract [Persian]

تحقیق حاضر عدد کروموزومی دو گونه Tanacetum به نام‌های T. stapfianum (Rech. f.) podlech (2 جمعیت) و T. lingulatum (Boiss.) Bornm. (یک جمعیت) را برای اولین بار گزارش می‌کند. این گونه‌ها متعلق به خانواده Asteraceae و جزء گیاهان انحصاری ایران می‌باشند. پارامتر‌های کروموزومی آنها بررسی شد. هر دو گونه دیپلوئید و دارای فرمول کاریوتایپی 18x=2n =2 بودند. ایدیوگرام آنها نیز رسم گردید.
