Abstract

Chromosome numbers of two native species from Iran were determined. The samples were collected from natural habitats. Astrodaucus orientalis (2n=20) of Apiaceae family and Althaea officinalis (2n=42) of Malvaceae family were investigated in this research. Ideograms were depicted for each species. Althaea officinalis had metacentric chromosomes. In Astrodaucus orientalis the karyotype formulas are 8m+ 2sm. These results are the first report for the Iranian flora.

Abstract [Persian]

تعداد کروموزوم دو گونه بومی از ایران مشخص شد. نمونه ­ها از رویشگاه طبیعی جمع­ آوری شدند.Astrodaucus orientalis (2n=20  از خانواده Apiaceae و Althaea officinalis(2n=42) از خانواده Malvaceae در این تحقیق مورد بررسی قرار گرفتند. برای هر گونه ایدیوگرام رسم شد. کروموزومهای گونه Althaea officinalis متاسانتریک می­ باشد.فرمول کاریوتایپی Astrodaucus orientalis ، 8 m+ 2sm است. این نتایج اولین گزارش برای فلور ایران است.
