Arbuscular mycorrhizal fungi in different forest covers in Vitória da Conquista, Bahia state, Brazil

Abstract

Arbuscular mycorrhizal fungi (AMF) are obligate mutualistic organisms that facilitate the survival and development of plants. They are influenced by forest cover and other biotic and abiotic factors. In this study, we aimed to evaluate the composition and diversity of AMF in the soil under three different forest covers in the municipality of Vitória da Conquista, Bahia state. The planting of Madeira nova showed greater abundance of spores then the planting of Eucalyptus. The Native Forest fragment showed a larger number of species when compared with plantations, with six unique species of the area studied, with potential to develop even greater diversity. AMF presented significant differences in composition and diversity in the forest covers assessed. The great abundance of spores and the homogeneity of sample species in the planting of Madeira nova are facilitating factors for further isolation of AMF.
