Resumo: In an experiment with 3 stand densities and 12 prune treatments there were analyzed the effects of stand density, prune and interaction between them on the yield of a Pinus taeda L. plantation. The stand variables analyzed were diameter at breast height (DBH), stem volume, volume per hectare, height, basal area, diameter over stubs (DMSM), Girard form coefficient (CFG), diameter of branch (DRBC) and branche’s angle (ARBC) at crown base. In the treatments with high density there were observed higher volume per hectare, basal area, CFG and lower DBH, stem volume, DMSM, DRBC and ARBC. In the treatments with lower prune height there were observed higher DBH, stem volume, volume per hectare, basal area than the treatments with larger prune height. Lower DMSM was observed with final prune height of 3,30 m and 4,40 m made at the age of 4 year. Higher DMSM were observed with final prune height of 5,5 and 6,6 m made at the age of 5 year. No statiscaly significant effects were found of the prune treatments over DRBC, ARBC and CFG or interaction between stand density and prune height. The density and prune yield effects were independent from each other.

Las variables evaluadas fueron el diámetro a la altura de pecho medio (DAP), la altura media, el volumen individual, el volumen por unidad de superficie, el área basal, el diámetro máximo sobre muñón (DMSM), el coeficiente de forma de Girard (CFG), el diámetro de ramas (DRBC) y el ángulo de inserción de las ramas (ARBC) en la base de la copa. En los tratamientos con mayor densidad de plantación se observaron mayores volúmenes por unidad de superficie, área basal y CFG que en los tratamientos con menor densidad. Estos produjeron mayores DAP, volúmenes individuales, DMSM, DRBC y ARBC que los tratamientos con mayores densidades. Los tratamientos con menores alturas finales de poda produjeron mayores DAP, volúmenes individuales, área basal y volúmenes por unidad de superficie que los tratamientos con mayores alturas de poda. Los menores DMSM se obtuvieron con alturas finales de poda de 3,30 m y 4,40 m realizadas a los 4 años de edad y los mayores DMSM ocurrieron al no efectuarse podas a los 5 años hasta 5,50 m y 6,60 m. No se encontraron diferencias significativas entre los valores medios de DRBC, ARBC y CFG producidos por los 12 tratamientos de poda. La interacción entre densidad y los tratamientos de poda no fue significativa para ninguna de las variables respuestas.Universidade Federal de Santa Maria2005-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/186510.5902/198050981865Ciência Florestal; Vol. 15 No. 3 (2005); 275-284Ciência Florestal; v. 15 n. 3 (2005); 275-2841980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1865/1112Costas, RubénDonagh, Patricio MacWeber, ElizabethFigueredo, SantiagoIrschick, Pedroinfo:eu-repo/semantics/openAccess2017-05-16T10:59:05Zoai:ojs.pkp.sfu.ca:article/1865Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-16T10:59:05Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
