Abstract
The liming effects on the growth of fifteen woody species of Brazil 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 efficiency (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 pioneer and secondary species.
Em condições de casa de vegetação foram avaliados os efeitos da calagem no crescimento de quinze espécies florestais nativas do Brasil. Foram utilizadas espécies pertencentes aos grupos ecológicos de plantas pioneiras, secundárias e clímax. Os tratamentos de solo consistiram na ausência de calagem (-LIM) e calagem até atingir pH=6,0 (+LIM). Em geral, as espécies pioneiras e secundárias apresentaram as maiores respostas à calagem quanto à produção de matéria seca total (TDM), enquanto que as espécies clímax não foram afetadas pelos tratamentos de solo. A classificação das quinze espécies em relação à tolerância à acidez do solo variou de altamente sensíveis a altamente tolerantes. As espécies pioneiras e secundárias, quando cresceram em solo corrigido (+LIM), apresentaram maiores conteúdos de Ca, Mg e P e baixa eficiência de utilização de Ca e Mg (CaUE e MgUE, respectivamente); porém, a eficiência de utilização de P (PUE) foi maior neste tratamento. Em contraste, os conteúdos de Ca, Mg e P das espécies clímax foram apenas levemente afetados pela calagem. Em geral, as espécies clímax foram menos eficientes do que as pioneiras e secundárias em utilizar o Ca e o Mg.
