Mature wood
As frost wood is wood denotes that in the central part ( core wood ) is significantly lower water content than the surrounding sapwood has (fresh) and no color core. At most it is a little darker. In the case of the elm ( ulmus ), the ripening wood forms the transition to the sapwood, it is a heartwoodening tree .
In the ripening wood, the water-conducting cells are inoperative and the parenchymal cells have died.
Different types of trees, such as European beech and pear , sometimes show abnormal coloring of the wood body. This is called a false core because they are non- core types of wood. Other species with ripening wood are Norway spruce ( Picea abies ), field maple ( Acer campestre ) and the white fir ( Abies alba ).
According to more recent terminology, a tree with a lighter heartwood is called a mature wood tree.
