Conteúdo: | The liming effects on the growth of fifteen woody species from Cerrado region (the Brazilian savannah) were evaluated under glasshouse conditions. The species used belong to different ecologic groups, namely: pioneer, secondary and climax trees. The soil treatments consisted in the absence of liming (-LIM) and liming sufficient to reach soil pH 6.0 (+LIM). In general, the pioneer and secondary species presented higher responses in total dry matter production (TDM) to soil liming, whereas the TDM of the climax species were not affected by the soil treatments. Thus, the ranking of species in relation to soil acidity tolerance ranged from highly sensitive to highly tolerant. The pioneer and secondary species growing in limed soil (+LIM) showed higher calcium (Ca), magnesium (Mg) and phosphorus (P) contents, and, at the same time lower Ca, Mg utilization effeciency (CaUE and MgUE respectively), whereas the P utilization (PUE) was higher. In contrast, the Ca, Mg and P content in the climax species were only slightly affected by the soil liming. In general the climax species were less efficient in the CaUE and MgUE than the pioner and secondary species.
