The proportion of heartwood in conifer (Pinus sylvestris L., Picea abies [L.] H. Karst.) trunks and its influence on trunk wood moisture
pine spruce heartwood moisture content of wood
2015/4/24
As the tree age increases, the formation of heartwood takes place in the central part of the tree. Since there is a large difference in the moisture content between sapwood and heartwood in conifers, ...
