The potential for arbuscular mycorrhizal fungi (AMF) to influence the host species depends on their affinities and effects. Twenty three different AMF strains from nearby localities were evaluated for their symbiotic response with Piper longum (long pepper). Saplings were raised in 10 cm thick sand-soil mix inoculated with isolates of different AM fungi. Almost all the studied AMF strains showed increase in plant growth, biomass and nutrient content (N&P) over the control, while retarded growth response was observed with the inoculation of 6 different AMF species. Considering the shoot length, total biomass, nutrient content, chlorophyll content and root infection, pre-inoculation with 6 AMF species viz; Glomus fasciculatum, G. versiforme, G. clarum, Glomus sp. 2, G. mosseae and G. etunicatum appeared to be the most promising AM fungi for inoculating this medicinal plant.
