| Five aquatic sites of National Botanical Garden of Iran monthly were sampled from December 2003 to November 2004. Total number of 68 genera in 18 families and 11 orders of the planktonic Diatoms were identified. Among the families Bacillariaceae with 19 genera and species showed the highest species richness. Cymbellaceae (11 species), Naviculaceae (7 species), Surirellaceae (6 species), Pleurosigmataceae (4 species), Fragilariaceae and Achnanthaceae each with 4 species, Pinnulariaceae and Gomphonemaceae each with 2 species and Rhopalodiaceae, Cosmioneidaceae, Diadesmidiaceae, Amphipleuraceae, Catenulaceae, Melosiraceae, Mastogloiaceae, Stephanodiscaceae, Anomoeoneidaceae each with 1 species respectively presented in the studied sites. High population densities of species were observed in the cold seasons. | ||

| چکیده [English] | ||
| در طی این تحقیق دیاتومهای 5 برکه مصنوعی در باغ گیاهشناسی ملی ایران با نمونه برداری از آذر 1382 تا آبان 1383 مورد مطالعه و شناسایی قرار گرفتند. در این مطالعه 68 جنس و گونه متعلق به 18 تیره و 11 راسته از دیاتومها شناسایی گردید که تیره Bacillariaceae با 19 جنس و گونه بالاترین تنوع گونه ای را نشان داد. تیره های Cymbellaceae (11 گونه)، Naviculaceae (7 گونه)، Surirellaceae (6 گونه)، Pleurosigmataceae (4 گونه)، Fragilariaceae و Achnanthaceae (هر کدام با 4 گونه)، Pinnulariaceae و Gomphonemaceae(هر کدام با 2 گونه) و تیره های Catelunaceae، Amphipleuraceae، Diadesmidiaceae، Cosmioneidaceae ، Rhopalodiaceae، Anomoeoneidaceae، Stephanodiscaceae، Mastogloiaceae، Melosiraceae هر کدام با یک گونه در مراتب بعدی قرار گرفتند. حداکثر تراکم جمعیت گونه های مورد مطالعه در ماههای سرد سال مشاهده شد. | ||
