Abstract
The objective of the present study was to characterize the diversity of morphospecies of arbuscular mycorrhizal-forming fungi (AMF) associated with rhizosphere of Mombasa (Panicum maximum cv. Mombasa) pasture cultivation in Sampues María, Sucre, Colombia and bioaugmentation of AMF spores in trap crops with rice seedlings. The sampling was carried out in the rhizosphere of Mombasa plantations in the municipality Sampues, department of Sucre, Colombia. Spores, separation and identification of AMF morphospecies were isolated; biaumentation of spores was performed in trap culture and the growth capacity of AMF was evaluated. A total of 67 morphospecies were distributed in 9 genera: Glomus, Acaulospora, Ambispora, Sclerocystis, Diversispora, Funneliformis, Scutellospora and Entrophospora. Treatments with Glomus geosporum, Glomus multicaule, Glomus agreatum and the AMF consortium induce chlorophyll production, increased stem length and bioaugmentation of spores / g of soil. The individual and consortium AMF morphospecies become an alternative for the production of bio-inputs with these fungi for their use and the promotion of growth in of Mombasa pasture on livestock farms in the department of Sucre.
