Possibility of using non-destructive spectrophotometery to detect the poplar tension wood and spruce compression wood in freshly cut and dried timbers

In this study, the potential use of spectrophotometery and CIELAB technique was evaluated to detect reaction woods, including poplar tension wood and spruce compression wood. Thus, two trees of spruce ( Picea abies) and poplar (Populous nigra) containing reaction wood were cut from a forest belongi...
