Abstract

This study aimed to estimate biomass and organic carbon in stands of Pinus taeda L. at different ages (14, 16, 19, 21, 22, 23 and 32 years) and located in the municipality of General Carneiro (PR). In order to estimate biomass and organic carbon in different tree components (needles, live branches, dead branches, bark and stem wood), the destructive quantification method was used in which seven trees from each age category were randomly sampled across the stand. Stocks of biomass and organic carbon were found to vary between the different age categories, mainly as a result of existing dissimilarities between ages in association with forest management practices such as thinning, pruning and tree density per hectare.Objetivou-se estimar a biomassa e carbono orgânico em plantios de Pinus taeda L. com diferentes idades (14, 16, 19, 21, 22, 23 e 32 anos), localizados no município de General Carneiro, PR. Para estimar a biomassa e o carbono orgânico nos diferentes componentes das árvores (acículas, galhos vivos, galhos mortos, casca e madeira do fuste) foi utilizado o método destrutivo de quantificação, utilizando-se para tanto a amostragem de sete árvores distribuídas aleatoriamente pelo plantio em cada uma das idades. O estoque de biomassa e carbono orgânico nas diferentes idades consideradas variou, principalmente, em função das diferenças existentes entre as idades, também relacionadas às condições de manejo, como desbastes, desramas e densidade de indivíduos por hectare.
