Resumo: | The productive sustainability of eucalyptus planting is threatened when both diseases and disorders of growth occur. These interferences can have abiotic origin as environmental conditions can negatively affect the wood quality. This study has the goal of evaluating influence of different levels of physiological disorders in dendrometric variables and wood quality from seven-year-old Eucalyptus grandis x Eucalyptus urophylla hybrids intended for wood pulping production. The trees from commercial plantations in State of Maranhão, Brazil were separated into three levels of physiological disorders by means of morphologic changes. Then, they were evaluated according to dendrometric variables, anatomical characteristics, chemical properties, density of wood, and kraft pulp process. The physiological disorder levels significantly influenced all evaluated properties. Moreover, the wood from trees with higher severity of symptoms resulted in higher average values of dendrometric variables, basic density, and fibers dimensions. In addition, apparent density exhibited a different standard in the pith region with increase on radial wood profile. Trees with the least severe disorders exhibited changes in dendrometric and anatomical variables, mainly in wood volume and fibers dimensions, respectively. |

Essas interferências podem ter origem abiótica, e como condições ambientais podem afetar negativamente a qualidade da madeira. Este estudo tem como objetivo avaliou a influência de diferentes níveis de distúrbios fisiológicos em variáveis dendrométricas e qualidade da madeira dos híbridos Eucalyptus grandis x Eucalyptus urophylla de sete anos destinados a produção de polpa celulósica. As árvores de plantações comerciais no estado do Maranhão, no Brasil, foram separadas em três níveis de distúrbios fisiológicos por meio de alterações morfológicas visuais. Em seguida, foram avaliados de acordo com variáveis dendrométricas, características anatômicas, propriedades químicas, densidade de madeira e processo de polpa Kraft. Os níveis de distúrbio fisiológico influenciaram significativamente todas as propriedades avaliadas. A madeira de árvores com maior gravidade dos sintomas resultou em maiores valores médios de variáveis dendrométricas, densidade básica e dimensões das fibras. Além disso, a densidade aparente exibiu um padrão diferente na região da medula com aumento do perfil radial da madeira. As árvores com os distúrbios menos severos apresentaram alterações nas variáveis dendrométricas e anatômicas, principalmente no volume da madeira e nas dimensões das fibras, respectivamente.CERNECERNE2018-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://cerne.ufla.br/site/index.php/CERNE/article/view/1785CERNE; Vol. 24 No. 1 (2018); 27-34CERNE; v. 24 n. 1 (2018); 27-342317-63420104-7760reponame:Cerne (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAenghttps://cerne.ufla.br/site/index.php/CERNE/article/view/1785/1060Copyright (c) 2018 CERNEinfo:eu-repo/semantics/openAccessCâmara, Ana PaulaOliveira, José Tarcísio da SilvaBobadilha, Gabrielly dos SantosVidaurre, Graziela BaptistaTomazello Filho, MarioSoliman, Everton Pires2018-07-25T11:27:37Zoai:cerne.ufla.br:article/1785Revistahttps://cerne.ufla.br/site/index.php/CERNEPUBhttps://cerne.ufla.br/site/index.php/CERNE/oaicerne@dcf.ufla.br||cerne@dcf.ufla.br2317-63420104-7760opendoar:2024-05-21T19:54:35.179032Cerne (Online) - Universidade Federal de Lavras (UFLA)true |
