Resumo: The objective of this study was to estimate the litter production and decomposition rate, litter renewal and decomposition period in Tectona grandis Linn. F. (Teca) populations. The research was carried out in three different populations located in the city of Nossa Senhora do Livramento – MT state. Litter fall was collected from a limited forest area of 1 (one) ha containing plots with five, six and seven years old, from 20 wood collectors suspended and cast, covering an area of 0,64 m². The accumulated material was collected every 30 days, for 12 months, sent to the laboratory and segregated into leaves, branches (less than one centimeter in diameter) and mixed material, then dried and weighed. The litter fall collected from plots with seven, six and five years old had, respectively, 7,280.25; 6,739.42 and 6,419.61 kg ha-1. The leaves corresponded to 86% of the deposited litter, branches, 4%, and mixed material, 10%. The decomposition rate constant (K) of the plots with five, six and seven years old were, respectively, 0.54; 0.60 and 0.58. The average time of material renewal per plot, in years, was of 1.84 (671 days) for those with five, 1.67 (609 days) for those with six and 1.71 (624 days) for those with seven years old. The estimated time to decompose 50% of the litter material in the plots consisted in 1.28 years (467 days), 1.15 years (419 days) and 1.19 years (434 days) to the plots with five, six and seven years old, respectively. The estimated time to decompose 95% of the litter fall collected from plots with of five, six and seven years old consisted in 5.53 years (2018 days), 5.00 years (1825 days) and 5.14 years (1876 days), respectively.

F. (Teca). O estudo foi realizado em três povoamentos de teca localizados no município de Nossa Senhora do Livramento - MT. Para as coletas da serapilheira foi delimitada uma área de 1 (um) ha em cada talhão com idades de cinco, seis e sete anos, na qual foram distribuídos, aleatoriamente, 20 coletores de madeira suspensos e vazados, com área de 0, 64 m2. O material vegetal depositado nos coletores foi recolhido a cada 30 dias, durante 12 meses, levado ao laboratório separando-se folhas, ramos (menores que um centímetro de diâmetro) e miscelânea, e depois de secos foram pesados. A serapilheira produzida nos talhões com sete, seis e cinco anos de idade foi, respectivamente, 7.280,25; 6.739,42 e 6.419,61 kg ha-1. As folhas representaram 86% do total de serapilheira depositada, os ramos, 4%, e as miscelâneas, 10%. As constantes de decomposição da serapilheira (K) nas árvores com cinco, seis e sete anos de idade foram, respectivamente, de 0,54; 0,60 e 0,58. O tempo médio de renovação, em anos, foi de 1,84 (671 dias) aos cinco anos, 1,67 (609 dias) aos seis anos e 1,71 (624 dias) aos sete anos. Para que ocorresse a decomposição de 50% da serapilheira, o tempo médio estimado foi de 1,28 anos (467 dias), 1,15 anos (419 dias) e 1,19 anos (434 dias) para as árvores com cinco, seis e sete anos, respectivamente. Para a decomposição de 95% da serapilheira, o tempo médio estimado foi de 5,53 anos (2.018 dias), 5,00 anos (1.825 dias) e 5,14 anos (1.876 dias) para a mesma sequência das idades.Universidade Federal de Santa Maria2017-12-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3028810.5902/1980509830288Ciência Florestal; Vol. 27 No. 4 (2017); 1117-1127Ciência Florestal; v. 27 n. 4 (2017); 1117-11271980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/30288/pdfCopyright (c) 2017 Ciência Florestalinfo:eu-repo/semantics/openAccessRosa, Tania de Fátima de DeusScaramuz, Walcylene Lacerda Matos PereiraFeitosa, Isadora PiresAbreu, Fernanda Feboli Mansano de2017-12-11T22:38:44Zoai:ojs.pkp.sfu.ca:article/30288Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-12-11T22:38:44Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
