ABSTRACT:     The objective of this study was to test the effect of shading levels and leaf reduction intensities on the survival and growth of Copaifera langsdorffii Guillem. ex Benth., Copaifera langsdorffii Desf. and Hymenaea courbaril L. seedlings rescued from natural regeneration. Three experiments were conducted in a completely randomized design with split-plots, in which four shading composed the plots (0 or full sun; 30; 50; and 70%) and three leaf reductions intensities composed the subplots (0; 50; and 100%). General average survival after six months from the rescue was 47.6% for C. tomentosum, 44.6% for H. courbariland 21.4% for C. langsdorffii. Considering the height, only C. tomentosum demonstrated a significant effect of leaf reduction and shading, with total or partial maintenance of leaves (0% or 50% of leaf reduction) and the when under up to 50% shading providing a greater increment. Leaf reduction is not necessary for rescuing the seedlings from H. courbaril and C. langsdorffii, whereas the leaf reduction of 50% intensity is advised to enhance the survival of C. tomentosum species. As for shading, 50% is the most suitable level for acclimatization of H. courbaril and C. tomentosum seedlings while for C. langsdorffii the level is 70%.

RESUMO:    Este  trabalho  teve  como  objetivo  avaliar  o  efeito  de  diferentes  sombreamentos  e  reduções  da  lâmina  foliar  na  sobrevivência e crescimento de mudas das espécies Copaifera langsdorffii Guillem. ex Benth., Copaifera langsdorffii Desf. e Hymenaea courbaril L.  provenientes do resgate da regeneração natural. Três experimentos foram conduzidos em delineamento inteiramente casualizado, em parcelas subdivididas, cujas parcelas foram quatro níveis de sombreamento (0 ou pleno sol, 30, 50 e 70 %) e as subparcelas três intensidades de redução foliar (0, 50 e 100 %). A sobrevivência média geral após seis meses do resgate foi de 47,6 % para a espécie C. tomentosum, 44,6 % para H. courbaril e 21,4 % para C. langsdorffii. Para a altura, apenas C. tomentosum apresentou efeito significativo da redução foliar e do sombreamento, sendo que a manutenção total ou parcial das folhas (0 % ou 50 % de redução foliar) e o acondicionamento sob até 50 % de sombra proporcionaram maior incremento. Para o resgate de plantas jovens de H. courbaril e C. langsdorffii não há necessidade de realizar a redução foliar, já para a espécie C. tomentosum recomenda-se a redução foliar de 50 % de intensidade, visando potencializar a sobrevivência. Quanto ao sombreamento, 50 % é o nível mais indicado para aclimatação de mudas de H. courbaril e C. tomentosum, e 70 % para a espécie C. langsdorffii..
