ABSTRACT The aim of this work was to evaluate the community of arbuscular mycorrhizal fungi spores in five areas cultivated with eucalipt ( Eucalyptus grandis W. Hill ex Maiden), pinus ( Pinus elliottii Engelm. var. elliottii) and native field, in arenization process, located in São Francisco de Assis-RS. The study of arbuscular mycorrhizal fungi spore community was carried out by direct and indirect identification and the diversity index determination. The analyzed areas were native field, 2 and 6 years-old eucalypt field and 2 and 12 years-old pinus field. The obtained results showed that the most frequent genera were Acaulospora , Scutellospora and Glomus . The highest diversity of species was found in area of native field, followed by 2 years-old Eucalyptus area. The Cluster analyses showed a similarity of the minimum 70 % to the species of FMAs identified through spores and 50 % to the areas being studied.

    • "Diferenças na esporogênese e na morfologia dos esporos (cor, tamanho, estrutura e espessura das paredes) podem ter contribuído para a predominância deste gênero (Santos & Carrenho, 2011). A dominância de um ou mais gêneros de FMAs em determinado ambiente pode ser o resultado da interação de alguns fatores do ambiente, como: as características físicas e químicas do solo, as características morfológicas e fisiológicas das plantas, a compatibilidade genética das espécies de fungos e plantas que ocorrem no local, a dispersão dos fungos e a extinção de algumas espécies do local (Zangaro & Moreira, 2010; Silva et al., 2008).

    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.
