The properties of softwood tracheids vary within a tree. This within-t
ree variation is a major source of variation between trees and stands.
The effect of cambium age on the length, coarseness, and strength of
Pinus silvestris and Picea abies tracheids is discussed. Distributions
and correlations of Pinus silvestris tracheids within two age classes
are introduced. Between pulps of different cambium age group, fiber l
ength and coarseness are correlated; but within an age group, no corre
lation exists between fiber length and cross-sectional fiber dimension
s. Between age groups, the major source of coarseness variation is cel
l-wall thickness; but within age groups, fiber perimeter also contribu
tes to coarseness.
