Using Lignin Content, Cellulose Content, and Cellulose Crystallinity as Indicators of Wood Decay in Juglans mandshurica Maxim. and Pinus koraiensis

Using Lignin Content, Cellulose Content, and Cellulose Crystallinity as Indicators of Wood Decay in Juglans mandshurica Maxim. and Pinus koraiensis

The main chemical indicators for healthy wood and rotted wood at different decay levels in two species, namely Juglans mandshurica Maxim. and Pinus koraiensis, were preliminary analyzed. The cellulose content, lignin content, and relative crystallinity were measured using the nitric acid-ethanol met...
