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.
