The influence of forest litter on the endomicorritic fungi community in a natural regeneration area in São Paulo State, Brazil¹

Influência da serapilheira florestal na comunidade de fungos endomicorrízicos em área de regeneração natural no interior do Estado de São Paulo, Brasil

ABSTRACT

Natural areas of high biological diversity are being degraded to meet man’s need to convert them to various uses. The ecological restoration through litter transposition enables for the reestablishment of ecological processes and may contribute to the increase of microorganisms. It aimed to evaluate the influence of litter on the community of mycorrhizal fungi in an area of Cabreúva, São Paulo State, Brazil. Ten plots were delimited, five control and five treatment. Soil samples were collected during two distinct periods for physical, chemical and microbiological analysis. Results indicated that the edaphic conditions of the place are consistent with the presence of AMF; also, the transposed organic matter did not increase species richness and did not facilitate the colonization of plant species, whereas gravimetric humidity and grass may have influenced species richness.
