NMR studies on Fraser fir Abies fraseri (Pursh) Poir. lignins

The composition of mature, juvenile uninfested and juvenile infested Fraser fir wood (Rotholz) and the structures of lignins isolated from these woods were elucidated to verify differences between juvenile and mature wood and the effect of balsam woolly adelgid (BWA) infestation...

Keywords: balsam woolly adelgid (BWA), carbohydrate composition, Fraser fir, juvenile wood, lignin, NMR spectroscopy, Rotholz wood

Morphological and chemical variations between juvenile wood, mature wood, and compression wood of loblolly pine (Pinus taeda L.)

To better understand the within-tree variations between juvenile wood, mature wood, and compression wood, wood from a 35-year-old mature bent loblolly pine was separated into seven groups by different positions in the tree...
