For example, rather than representing "noise" and "aberrations", it seems just as plausible that selection should favor very high variation in features such as libriform fiber length; high variability in length could be favored by selection in that it would diminish the occurrence of fracture planes that would result if cells were aligned, while still resulting in mechanical and hydraulic characteristics that meet the needs of the stem given its size.
Vessels and a parenchyma cells are embedded in a tissue consisting of thin-walled libriform wood fibres.
High degree--rupturing wood cell pore membranes, resin boiling and replacement, destroying tyloses (in hardwood species), rupturing ray cells, rupturing main cell (traheids, libriform, parenchyma) walls and walls of vessels, and formation of cavities being primarily in radial--longitudinal planes.
For example, the diameter of the largest vessel elements of Populus tremuloides, one of the typical wood species used in OSB production, is 50 [micro]m to 100 [micro]m; and its libriform fibers are 20 [micro]m to 30 [micro]m (Panshin and deZeeuw 1980).
