Abstract | ||
جهت بررسی نمونه های خاکزی خانواده Nostocaceae Kützing، تاکسونهای موجود در خاک 20 ایستگاه از 7 استان دارای کشت برنج کشور مورد مطالعه قرار گرفت. طی این تحقیق در مجموع تاکسونهایی متعلق به 6 جنس از این خانواده شناسایی شد که از میان تاکسونهای شناسایی شده، 18 گونه و 1 واریته از 4 جنس Nostoc Vaucher ex Bornet & Flahault، Trichormus (Ralfs ex Bornet & Flahault) Komárek & Anagnostidis ، Nodularia Mertens ex Bornet & Flahault و Aulosira Kirchner ex Bornet & Flahault دارای ساختار ترایکمی آپوهتروسیتیک و 20 تاکسون از 2 جنس Anabaena Bory ex Bornet & Flahault و Cylindrospermum Kützing ex Bornet & Flahault دارای ساختار پاراهتروسیتیک میباشند. از میان گونه های شناسایی شده از این خانواده، چهار گونه زیر برای نخستین بار از ایران گزارش میشوند و کلید شناسایی، محدوده پراکنش و تصاویر کامرا لوسیدای گونه های شناسایی شده، به همراه شرح گونه های جدید با تاکید بر تاکسونهای دارای ساختار آپوهتروسیتیک ارائه میگردد. Nostoc linckia var. arvense C. B. Rao, Nostoc alatosporum Sant Anna & al., Nostoc spongiaeforme Agardh ex Born. & Flah. and Nostoc verrucosum Vaucher ex Born. & Flah. | ||
