|Description: ||This paper presents the results of a research carried out to evaluate the defects caused by growth stresses on boards produced from Eucalyptus grandis and Eucalyptus dunnii, using two different sawing models. Logs tested came from fast growing plantations belonging to two diametric classes. The first sawing model used aimed to produce mainly flat sawn boards and the second aimed to maximize the production of quarter-sawn boards. The results obtained pointed out that quarter-sawn boards were more prone to twist and bow. Splits were more evident in flat sawn boards. Bow was only observed in flat sawn boards. As a result of the drying schedule used, collapse was not a problem. Under the conditions of the study, regardless the species or log diameter, the best result is obtained when flat sawn boards are produced. Eucalyptus grandis was found to be a better species for producing sawnwood than Eucalyptus dunnii. |
