Resumo: | Litterfall is the main responsible for maintaining forest stands yield in soils with low natural fertility. This study aimed to evaluate seasonal and monthly litterfall deposition in a Pinus taeda L. stand, in Quedas do Iguaçu, Paraná State, Brazil. Three plots with 21.0 m x 20.0 m were randomly allocated, where four collectors of 1.0 m2 each were systematically distributed. The litterfall was monthly collected, between April 2007 and March 2009, respectively at eight and nine years after the stand plantation, and divided in needles, thin branches (diameter < 0.5 cm), and miscellaneous, being subsequently determined its dry mass. The litterfall annual deposition reached 7.1 Mg ha-1, being higher in the autumn. The average maximum temperature and average air temperature had inverse and significant influence on needles deposition and total litterfall. |

Objetivou-se, com este trabalho, avaliar a deposição mensal e estacional de serapilheira em um povoamento de Pinus taeda L., no município de Quedas do Iguaçu (PR). Instalaram-se, ao acaso, três parcelas de 21,0 m x 20,0 m, nas quais distribuíram-se, sistematicamente, quatro coletores de 1,0 m² cada. As coletas foram realizadas mensalmente, entre abril de 2007 e março de 2009, respectivamente aos oito e nove anos de idade do povoamento. A serapilheira foi separada nas frações acículas, galhos finos (diâmetro < 0,5 cm) e miscelânea, sendo, posteriormente, determinada a massa seca. A deposição anual de serapilheira foi de 7,1 Mg ha-1, com deposição superior no outono. A temperatura máxima média e a temperatura média do ar apresentaram influência inversa e significativa na deposição de acículas e na serapilheira total.Escola de Agronomia - Universidade Federal de Goiás2012-07-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/15131Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 42, n. 2, Apr./Jun. 2012; 206-211Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 42, n. 2, abr./jun. 2012; 206-211Pesquisa Agropecuária Tropical; v. 42, n. 2, abr./jun. 2012; 206-2111983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/15131/11184Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessPiovesan, GabrielSchumacher, Mauro ValdirViera, MárcioLopes, Vicente GuilhermeWelter, Carline2020-07-10T11:24:34Zoai:ojs.revistas.ufg.br:article/15131Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:53.010001Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
