Plants roots are colonized by soil inhabitants known as arbuscular mycorrhizal fungi (AMF), which increase plant productivity, and enhance carbon storage in the soil. We found mycorrhizal vesicles, arbuscles, and mycelium in the root of more than 89% of the selected plants of University of Rajshahi campus, Bangladesh. The rate of their presence differed in plant to plant of a family and different families. The highest root colonization (98±1.0%) was found to be present in Xanthium strumarium (Asteraceae). Mycorrhiza was not found in the root of Sphagneticola calendulacea (Asteraceae), Cestrun nocturnum (Solanaceae), Acacia nilotica and Acacia catechu (Mimosoidae), Rorippa nasturtium, Brassica oleracla var botrytis (Brasicaceae), Punica granatum (Lythraceae), Tecoma capensis (Bignoniacea), Spinacia oleracia (Chenopodiaceae), Chenopodium album (Goosefoot). Result of soil analysis reveals that the rhizospheric soils were deficient in nutrients which might be suitable for mycorrhizal symbiosis with plants. In the rhizospheric soils, 22 species of Glomus, Scutelospora, Gigaspora, Archaeospora, and Acullospora were found. We also found the genera 'Glomus' dominance in the plant root and rhizospheric soil. So, it can be concluded that the highly colonized roots as well as spores can be used to prepare mycorrhizal inoculum for future purposes.
植物的根系被土壤中的居民（称为丛枝菌根真菌，AMF）所定植，这些真菌可以提高植物的生产力，并增强土壤中的碳储存。我们在孟加拉国拉杰沙希大学校园的超过 89%的选定植物的根中发现了菌根泡囊、丛枝和菌丝体。它们的存在率在同一科的不同植物之间以及不同科之间存在差异。在 Xanthium strumarium（菊科）中发现了最高的根系定植率（98±1.0%）。在 Sphagneticola calendulacea（菊科）、Cestrun nocturnum（茄科）、Acacia nilotica 和 Acacia catechu（含羞草科）、Rorippa nasturtium、Brassica oleracla var botrytis（十字花科）、Punica granatum（千屈菜科）、Tecoma capensis（紫葳科）、Spinacia oleracia（藜科）和 Chenopodium album（藜科）的根中未发现菌根。土壤分析的结果表明，根际土壤缺乏营养物质，这可能有利于与植物的菌根共生。在根际土壤中，发现了 22 种 Glomus、Scutelospora、Gigaspora、Archaeospora 和 Acullospora。我们还发现“Glomus”属在植物根和根际土壤中占优势。因此，可以得出结论，高度定植的根系以及孢子可以用于为未来的目的制备菌根接种剂。
