Tolerance of Eucalptus Trees to the Action of Storms and Their Relationships with Wood Properties

摘要：

Summerstorms have caused serious damage in Eucalyptus plantations at several regions in Brazil．The pattern of damage varies from a light bending of stems through to the tree breaking．At the Vale do Rio Doce region，Minas Gerais State，it appears that the tolerance of the trees to the storms depends on both the genetic material and the environment where they grow．It has also been reported that damage mostly occur when the trees are twenty—four—months—old．Thus，the objective of this work was to report the results of research on wood of Eucalyptus clones．Non—destructive and destructive assessments were carried out in the trees and wood．Up to this stage of the studies it has been found that trees cultivated on flat land are less tolerant to storms．These trees normally produce wood with higher values of fibre length，width，lumen diameter and wall thickness；small microfibril angles，small values of mechanical properties and low growth stresses． Analyses of regression revealed that the tolerance of clones to storms was better estimated by fibre width and by growth stresses．
