Genetic variation of juvenile wood properties in a loblolly pine progeny test

摘要

Forest biologists and wood,paper scientists,and forest company have collaborated to study the genetic variation of several important phys-iochemical wood properties of loblolly pine [Pinus taeda L).Taking cores from 11-year-old trees,these scientists studied the genetic variation and the breeding potential to improve cellulose yield,fiber length,fiber coarseness,and lignin content for pulp andvpaper production.Earlywood and latewood of juvenile wood(Ring 3)and transition wood(Ring 8)were analyzed separately for these key traits.
