Abstract

The quality breeding for high pulp yield and strength in the pulp production has attracted interest especially for Eucalyptus. The increment core method without cutting a tree is effective and efficient in the practical quality breeding program [1], but this is an indirect selection method that requires the prediction of whole-tree properties using clear implications between wood and pulp properties. Derived wood properties, such as Runkel ratio, solid factor, vessel R/T ratio and fiber coarseness, have been recognized an important traits for pulp and paper properties in Eucalyptus [2]. We examined the within-tree variations of derived wood properties in E. camaldulensis and E. globulus trees with the aim of determining the representative height in the trunk to indicate whole-tree values.
