Resumo: | The objective of this work was to analyze the effect of single and double planting spacing on the basal area, stem wood and bark volume per hectare, stem basic density and above-ground biomass of Eucalyptus grandis Hill ex Maiden (G-21 clone) managed under the short rotation coppice system. Four planting spacings were considered: 3.0 m × 1.0 m × 2.0 m (double row), 3.0 m × 1.0 m (single row), 3.0 m × 1.0 m × 1.0 m (double row) and 3.0 m × 0.5 m (single row), which were evaluated at 12 months and at 24 months after planting. Main significant differences were found at 12 months after planting for both factors spacing and age. Basal area increased as planting densification, although the volume did not show the same trend at 24 months after planting. Basic density increased as age only at single rows. In the study of the biomass allocation in the different tree compartments, it was verified a higher proportion of stem biomass on older treatments and denser spacings. One of the highest forest productions (65 Mg ha-1) was found in the 3 m × 1 m planting spacing at 24 months of age. |

O ensaio foi composto por quatro espaçamentos de plantio: 3,0 m × 1,0 m × 2,0 m (linha dupla), 3,0 m × 1,0 m (linha simples), 3,0 m × 1,0 m × 1,0 m (linha dupla) e 3,0 m × 0,5 m (linha simples), sendo avaliado aos 12 meses e 24 meses após o plantio. As principais diferenças significativas foram encontradas no segundo período de avaliação para os fatores de variação considerados – espaçamento e idade. A área basal aumentou com o adensamento das florestas, embora o volume não tenha seguido a mesma tendência aos 24 meses de plantio. A densidade básica aumentou com a idade apenas nos espaçamentos simples. No estudo da alocação de biomassa nos diferentes compartimentos da árvore, verificou-se uma maior proporção de biomassa de tronco com a idade, bem como nos espaçamentos mais adensados. Uma das maiores produções florestais (65 Mg ha-1) foi encontrada no espaçamento 3,0 m × 1,0 m aos 24 meses de idade.Universidade Federal de Santa Maria2019-12-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3516610.5902/1980509835166Ciência Florestal; Vol. 29 No. 4 (2019); 1568-1578Ciência Florestal; v. 29 n. 4 (2019); 1568-15781980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/35166/35166Copyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessMachado, Felipe de CórdovaEufrade-Junior, Humberto de JesusSpada, GrasielaOguri, GuilhermeGarcia, Éder AparecidoGuerra, Saulo Philipe Sebastião2019-12-10T21:30:48Zoai:ojs.pkp.sfu.ca:article/35166Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2019-12-10T21:30:48Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
