Description:
Due to the low infectivity potential of arbuscular mycorrhizal fungi (AMF) in a mining area located at the State of Bahia, Northeastern Brazil, the effect of mycorrhization on the seedlings of Leucaena leucocephala was investigated, in order to use this species for revegetation of the area. Caatinga soils from both, natural (control) and mining impacted areas, were used to maintain seedlings inoculated with Glomus etunicatum. The soil from the impacted area was diluted 0, 25, 50, 75 and 100% with soil from the control area. In general, the increase in the proportion of contaminated soil had a negative effect on plant growth. Inoculated plants presented greater height, leaf number and dry matter of roots and shoots than the non-inoculated plants, when cultivated in soil with up to 50% of contaminated soil. Higher spore number was produced in substrate with 25% soil contamination. Mycorrhizal colonization was higher than 40% in those treated with <50% disturbed soil. Proportions of copper contaminated soil higher than 50%, inhibited plant growth, development of the AMF in the roots and consequently, the benefit of mycorrhization. The pattern of Cu and P absorption in Leucaena, associated or not with G. etunicatum, is maintained when the soil is up to 50% contaminated.
