| چکیده | ||
| In this study original mitotic chromosome counts are presented for 4 Oxytropis species from 4 sections of the genus Oxytropis in Iran including: O. bicornis (O. sect. Oxytropis) (2n = 2x = 16), O. suavis (O. sect. Ortholoma) (2n = 2x = 16), O. aucheri (O. sect. Eumorpha) (2n = 2x = 16) and O. karjaginii (O. sect. Janthina) (2n = 4x = 32). This report is the first cytogenetic analysis of these taxa. All taxa (with exception of O. karjaginii) are diploid and possess 2n = 2x = 16 chromosome number, consistent with the proposed base number of x = 8. In addition, meiotic chromosome count and behavior are presented for O. masanderanensis (O. sect. Ortholoma) (2n = 2x = 16). Although this taxon displayed regular bivalent pairing and chromosome segregation at meiosis, but some abnormalities were observed. | ||

| چکیده [English] | ||
| در این مطالعه، گزارش عدد کروموزومی میتوز برای 4 گونه متعلق به 4 بخش از جنس Oxytropis در ایران شامل O. bicornis از بخش Oxytropis (2n = 2x = 16)؛ O. suavis. از بخش Ortholoma (2n = 2x = (16،O. aucheri از بخش Eumorpha (2n = 2x = 16) وO. karjaginii از بخش Janthina (2n = (4x = 32 ارائه شده است. این گزارش اولین مطالعه سیتوژنتیکی بر روی این تاکسونها میباشد. تمام گونه های مورد مطالعه (به استثناء O. karjaginii) دیپلوئید هستند و عدد 2n = 2x = 16را نشان می دهند که با عدد کروموزومی پایه پیش بینی شده x = 8 مطابقت دارد. همچنین عدد کروموزومی و رفتار میوزی درO. masanderanensis متعلق به بخش Ortholoma مورد مطالعه قرار گرفت که عدد کروموزومی (2n = 2x = 16) را نشان داد. اگرچه جفت شدگی بیوالانها و تفکیک کروموزومها در این گونه عادی است، لیکن برخی ناهنجاریها در طی میوز در این گونه مشاهده میشود. | ||
