          Abstract

          RESUMO O objetivo deste trabalho foi avaliar os estoques de biomassa, carbono e nitrogênio da serapilheira acumulada em um fragmento de Floresta Estacional Semidecidual Montana e dois plantios florestais puros (um de Pterogyne nitens e outro de Eucalyptus urophylla), no sudoeste da Bahia. As amostragens da serapilheira foram realizadas nos períodos chuvoso e seco. A biomassa da serapilheira acumulada foi superior no povoamento de eucalipto (13,1 Mg.ha–1) e inferior no povoamento de P. nitens (1,5 Mg.ha–1), atingindo valores intermediários na floresta nativa (6,3 Mg.ha–1). Essa mesma sequência foi verificada para os estoques de carbono: 5,6 Mg.ha–1 (eucalipto), 2,7 Mg.ha–1 (floresta nativa) e 0,6 Mg.ha–1 (P. nitens). O povoamento P. nitens apresentou teores de N da serapilheira foliar compatíveis aos da floresta nativa. As maiores diferenças de biomassa, carbono e nitrogênio da serapilheira acumulada entre as estações chuvosa e seca foram verificadas nos povoamentos puros.

          ABSTRACT This study aimed to evaluate the biomass, carbon and nitrogen stocks in accumulated litter in a Semidecidual Seasonal Forest fragment and two pure forest plantations (Pterogyne nitens and Eucalyptus urophylla), located in the Southwest of Bahia. Litter samplings were carried out in the rainy and dry season. The biomass from accumulated litter was higher in eucalyptus stand (13.1 Mg ha–1) and lower in the Pterogyne nitens (1.5 Mg ha–1), reaching intermediate values in the native forest (6.3 Mg ha–1). This same sequence was checked for carbon stocks: 5.6 Mg ha–1 (eucalypt) 2.7 Mg ha–1 (native forest) and 0.6 Mg ha–1 (P. nitens). The P. nitens stand has N content of leaf’s litter compatible to the native forest. The greatest differences in biomass, carbon and nitrogen of accumulated litter between the rainy and dry seasons were found in pure stands.
