Levantamento de fungos micorrízicos arbusculares em associação a espécie vegetal Manihot esculenta Crantz

Cassava production in the state of Alagoas is mostly carried out by small rural producers who adopt little management technology, and routinely do not replace nutrients due to high cost chemical inputs. In this agricultural model, knowledge use strategies that include natural biological processes soil, mainly microbiota present environment, such as arbuscular mycorrhizal fungi (AMF), can be presented an alternative for biofertilization, since, Arbuscular mycorrhizae are symbiotic associations established between roots most plants non-pathogenic soil have beneficial effects, which improve plant growth productivity structure. Thus, aim study was evaluate density glomerospores native AMF genera rhizosphere cassava, Sergipana variety, well determine colonization evaluated culture. Soil collections were made cassava rhizosphere, at 90, 180, 270 360 days after planting (DAP). The average number each treatment DAP, main present, evaluation DAP performed. cultivation showed increase approximately 174.46% showing a significant difference AMFs when compared 90 period. Diversispora sp, Entrophospora Acaulospora Scutellospora Racocetra sp. cultivation, positive result colonization, with 61% rate species.
