Chemical properties of wood are under stronger genetic control than growth traits in Populus tomentosa Carr.

摘要

The genetic development of some wood quality characteristics in early stage is particularly attractive since these properties are generally inherited. A clear understanding of the genetic control of chemical properties of wood (extractives, holocellulose, and lignin content) and growth traits (tree height, diameter at breast height, and stem volume) of corewood is a prerequisite for breeding for higher wood quality in triploid hybrid clones of Populus tomentosa.
