Gomes,Simone da Silva; Gonçalves,José Leonardo de Moraes; Rocha,José Henrique Tertulino; Menegale,Marcella Leite de Campos.
ABSTRACT: Tolerance to acid soil is an important trait of Eucalyptus and Pinus species introduced into commercial forestry plantations in tropical ecosystems. The objective of this study was to evaluate the effect of the exchangeable Al on growth of the seedlings of two species and one hybrid of Eucalyptus and two species of Pinus. We also wanted to identify the role of the root cation exchangeable capacity (CEC) on Al tolerance. The experiment was conducted under controlled conditions in a greenhouse. The soil used was collected from the top layer of a red yellow Oxisol, from the Brazilian savanna region. The treatments consisted of different rates of P and the presence or absence of liming with CaCO3 and MgCO3. The species of Eucalyptus and Pinus showed...
