  rdf:value "The wood extending from the pith to the sapwood, the cells of which no longer participate in the life processes of the tree. Heartwood may contain phenolic compounds, gums, resins, and other materials that usually make it darker and more decay resistant than sapwood."@en, "Madera que se extiende desde la albura hasta la médula, cuyas células ya no participan en los procesos vitales del árbol. Puede contener compuestos fenólicos, gomas, resinas y otros materiales que suelen volverla más oscura y más resistente a la pudrición que la médula."@es ;
