Lignin Picea mariana

TABLE 4-4. Distribution of Lignin in Spruce (Black Spruce, Picea mariana) Tracheid"... [Pg.80]

To determine the distribution of lignin from bromine analysis, it is essential to know the reactivity of bromine toward lignin in different morphological regions. For black spruce (Picea mariana), Douglas-fir (Pseudotsuga menziesii) and loblolly pine (Pinus taeda), the lignin in the secondary wall of tracheids is 1.7... [Pg.138]

For softwoods, the distribution of lignin in black spruce (Picea mariana) obtained by the bromination-EDXA technique and UV microscopy has been compared. By applying the correction factor of 1.7 for bromination-EDXA, a good agreement was achieved between the results obtained by the two methods (Saka et al. 1982). [Pg.143]
