Abstract

A 7-year plantation of Eucalyptus grandis x Eucalyptus urophylla hybrid established in the vicinity of Mogi-Guaçu/SP was evaluated, according to a simulation of multiple use of the wood. Part of the raw material produced was sent to sawn wood industry. The quality and yield of the cellulose produced in laboratory of three wood portions of the plantation was compared. In Treatment 1, the cellulose produced from the whole wood of the trees was evaluated; in Treatment 2 only the first portion of the tree was used, from wood of the soil base up to 4m height, wood that would be destined to sawnwood in a multiple use situation; finally, Treatment 3 evaluated the portion of the wood above 4 m of height. The possible interferences of multiple use of the wood in the yield and quality of the cellulose were evaluated. The results demonstrated that the retreat of the most vigorous logs of the trees didn't harm the quality and yield of the cellulose.
