| Four species belonging to two subgenera of Iranian Allium species were chromosomally and karyotypically assessed, using squash technique and feulgen stain. Ploidy level of A. longivaginatum, A. hooshidaryae and A. remediorum (2n = 2x = 16) are reported for the first time. Results indicated that A. rotundum is tetraploid (2n=4x= 32). Two chromosome types (‘‘m’’, ‘‘sm’’) formed different karyotypic formulas. Mean chromosome length varied from 7.8-13.56 µm. The results show that Allium longivaginatum has the most asymmetrical karyotype. | ||

| چکیده [English] | ||
| چهار گونه از دو زیر جنس پیازهای ایران، با استفاده از تکنیک اسکواش و رنگ آمیزی فولگن، مورد ارزیابی کروموزومی و کاریوتیپی قرار گرفتند. سطح پلوییدی گونههایA. Longivaginatum ، A. hooshidaryae و A. remediorum (2n = 2x = 16) برای نخستین بار گزارش می شود. نتایج نشان داد که A. rotundum تتراپلویید (2n=4x= 32) است. دو تیپ کروموزومی (‘‘m’’, ‘‘sm’’) فرمول های کاریوتیپی مختلفی را تشکیل دادند. میانگین طول کروموزوم بین 8/7 -56/13 میکرومتر، متغیر بود. نتایج نشان می دهد که گونه A. longivaginatum دارای نامتقارن ترین کاریوتیپ است. | ||
