RESUMO

The maln objectives of this research were: 1) to study the response of Copaifera langsdorffii Desf. of three distinct provenance, "cerrado" (cerrado provenance), gallery forest (gallery forest provenance) and deciduous Torest (deciduous forest provenance), to soils with distinct physical and chemical characteristics; 2) to establish the response of these three provenance to waterlogging. The work was divided in four main experiments:a) The first experiment focused on the response of the three provenances to acid and calcareous soils.The seeds of the experiment were collected in the Distrito Federal, between August and September 1985, from 16 trees of the cerrado provenance, 19 trees of the gallery forest provenance and 12 trees from the deciduous forest provenance. The seeds were sown in plastic bags four replicates. Origin (cerrado, gallery forest and decidouos forest) and soil (cerrado, gallery forest and deciduous forest ) were the variables considered. The seedlings were kept in a green house with a light filter (sombrite) that reduced 70% of sunlight, at the Fazenda Água Limpa in Brasília (DF). Seedlings were harvested 150, 180, 210, 240, 270, 300, 360, 390, 450, 510 and 570 days after sowing. ...
