Abstract

Abstract Arbuscular mycorrhizal fungi (AMF) association in roots of four bamboo species Bambusa tulda Roxb., B. nutans Wall ex Munro, Bambusa pallida Munro and B. balcooa Roxb. grown in homestead area of five different localities of Assam were studied. AM spores were isolated from root rhizosphere soils of four bamboo species and identified tentatively and classified up to the genus level. Soil physico-chemical properties such as soil texture, pH, EC and per cent organic carbon were determined using standard methods. Five genera of AM spores including Glomus, Gigaspora, Acaulospora, Sclerocystis and one unidentified species were isolated from rhizosphere of bamboo species. Spores of Glomus species were found dominated over others. AM fungi spore number varied between sites and among four bamboo species. Variation in AM root colonization was not as marked as spore number and no correlation could be established in between AM spore and root colonization. Rhizosphere soils of B. nutans contained more diverse AM spore types i.e. 9) genera followed by B. pallida with 8 genera, 5 genera in B. tulda and least in B. balcooa with 4 genera. Texture of the soil is sandy loam and loamy. pH of the rhizosphere soils range from 5.0 to 7.3.E.C (µMho) ranges between 0.0918- 0.5529 and % soil organic carbon ranges between 1.81-3.49.
