چکیده

شمارش کروموزومی 19 جمعیت متعلق به 7 جنس و 11 آرایه ازتیره اسفناج (زیرتیره Salicornioideae ) از ایران گزارش می شود. کلیه واحدهای مورد مطالعه دارای عدد پایه کروموزومی 9=x می باشد. اولین گزارش کروموزومی برای گونه های Halostachys belangeriana ، Halopeplis pygmaea و Kalidium caspicum ارائه می شود. گونه های جنس Salicornia به دو گروه تتراپلویید و دیپلویید تقسیم‌بندی می شوند. گونه Salicornia persica که اخیرا به عنوان گونه بومی مرکز ایران شرح داده شده است، تتراپلویید می باشد. گروه دیپلویید را می توان در سه آرایه متفاوت تقسیم بندی کرد.
