Resumo: This study aimed to structure the production in volume of Pinus taeda L. stands, through a management diagram, based on the following parameters: population density, dominant height, average diameter of basal area and relative spacing index. The data used came from 128 permanent plots, which were measured annually up to 18 years of age and conducted at full density, with spacing of 1.5x1.0 m and 1.5x2.0 m. At the same time, data from permanent plots subjected to different thinning intensities were used, and the density was regulated by the relative spacing index. The management diagram elaborated allowed the prognosis of the volume per hectare, the average diameter of the basal area and the availability of growth space, through the relative spacing index, from the variables dominant height and number of trees with precision and low error of estimate.

Os dados utilizados são oriundos de 128 parcelas permanentes, as quais foram medidas anualmente até aos 18 anos de idade e conduzidas em densidade completa, com espaçamentos de 1,5 x 1,0 m e 1,5 x 2,0 m. Concomitantemente, foram utilizados dados de parcelas permanentes submetidas a diferentes intensidades de desbaste, sendo a densidade regulada pelo índice de espaçamento relativo. O diagrama de manejo elaborado permitiu a prognose do volume por hectare, do diâmetro médio de área basal e da disponibilidade de espaço de crescimento, através do índice de espaçamento relativo, a partir das variáveis altura dominante e número de árvores com precisão e baixo erro de estimativa.Universidade Federal de Santa Maria2020-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2721910.5902/1980509827219Ciência Florestal; Vol. 30 No. 3 (2020); 669-676Ciência Florestal; v. 30 n. 3 (2020); 669-6761980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/27219/33578Copyright (c) 2020 Ciência Florestalinfo:eu-repo/semantics/openAccessSchneider, Paulo RenatoSchneider, Paulo Sérgio PigatoLonghi, Solon JonasMendes, Junior OliveiraMeyer, Evandro Alcir2020-09-02T20:52:05Zoai:ojs.pkp.sfu.ca:article/27219Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2020-09-02T20:52:05Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
