A large remaining of dry deciduous forest (woody Caatinga) in semi-arid Brazil has been reached by successive fires and exploratory actions what leads to the invasion of low load trees and shrub mesh, called ?Carrasco vegetation?. As it restrains the sprouting of woody species, land recuperation was performed using a mixed plantation of native and Eucalyptus species to both preservation and to supply the demand for wood. In order to evaluate the recuperation, a study of microbial communities was proposed. In addition to the highest soil phosphorus content found in the Carrasco area, the greatest spore density of arbuscular mycorrhizal fungi (AMF) communities occurred in the rhizosphere of the both pioneer species: Carrasco and Eucalyptus. In contrast to the DGGE bacteria profile, it was possible to group AMF species of the preserved and experimental sites which were not clustered with Carrasco species through the DGGE of Glomales DNA and also by the principal component analysis (PCA) based on diversity index. Glomus and Acaulospora were the dominant genera at both the preserved site and Carrasco. Nevertheless, Gigaspora species were preferentially found in Dry Forest, while Scutellospora were absent. In contrast, Carrasco favoured the genus Scutellospora and the species Acaulospora scrobiculata. Our results allow one to conclude that vegetation type modifies the AMF communities, which may be used as good indicator of soil quality. Based on AMF communities as soil quality indicator, the mixed forest plantation appears to be underway towards the preserved site two years after transplantation.

Trinta cultivares de arroz de sequeiro, foram selecionadas para verificação de tolerância a M em solução nutritiva, a concentrações de 0, 10, 20, 40 e 60 ppm. Foram observados os efeitos do AI na produção de matéria seca das partes aéreas e raízes, o comprimento das raízes, e a altura da planta. Os modelos de regressão foram ajustados aos dados de comprimento das raízes do grupo de cultivam, tendo por base a sensibilidade delas a toxidez do alumínio. Partindo de testes de regressão, as cultivares foram agrupadas em alta, média e baixa tolerância ao alumínio. |
