Influence of Harvest Age on Kraft Pulp Production for Eucalyptus globulus planted in Uruguay

Abstract

Genetic materials of two E. globulus provenances (Jeeralang and Chivilingo) grown in western litoral and southeastern areas in Uruguay, with two shifts each harvest were evaluated. For each shift growth, cellulose productivity, and properties of cellulose fibers were evaluated. Age at harvest ranged from 6.6 to 10.7 years, and the period between assessments was approximately two years. In general results indicate an improvement in pulping properties, in the productive efficiency of transforming wood into pulp, and in fiber properties, with an increasing age of harvest.
