چکیده
The systematic state of the genus Fritillaria at the subgeneric level has been the subject of long debate. The genus was classified into various subgenera ranging from two to ten in different morphological e.g., bulbs, style, nectaries, and capsule, Karyological, and molecular studies. In this study scanning electron microscopy imaging of the filament and anther was used to revise the systematics of the genus at the subgeneric level. Several quantitative and qualitative characteristics including filaments' morphology, length, color, ornaments, and anthers' length, color, and attachment were studied in ۲۷ Fritillaria species. For the species under study, a clustering dendrogram was constructed based on these characters, and a phylogenetic tree was built using a phylogenetic backbone based on the botanical nomenclature of The Plant List in R software. The results showed some correspondence between the dendrogram and phylogenetic tree, indicating the relative usefulness of filament and anthers' ultrastructure characters in the systematics of Fritillaria at the subgeneric level. Moreover, both trees were correspondent in suggesting that the members of subgenus Fritillaria were not monophyletic, and a sister relationship between the subgenera Petilium and Theresia.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
