This article describes changes in the genetic variation of wood density components with cambial age and their relationship with the within-ring area components. Wood samples from 31 half-sib families of radiata pine were submitted to X-ray densitometry procedures. Traits studied were earlywood (ED) and latewood (LD) density, earlywood (EA) and latewood (LA) area, and latewood proportion (LP). Between rings 2 to 5 (juvenile wood) and 11 to 14 (mature wood), heritability estimates suggest that breeding for increased ED is feasible. Upward selection for ED would also be associated with a phenotypic reduction in EA in juvenile and mature wood. Between rings 6 to 10, the heritability estimates for ED indicate low genetic variation in the transit...
