Development and properties of tracheids and their cell wall layers in eastern hemlock (Tsuga canadensis L.)
… chemical constitution of the partially developed tracheids were used to calculate physical and chemical properties of individual cell wall layers. Results showed that 59% of the middle lamella and primary wall was lignin, but these layers contained only 19% of the cells total lignin content. …

Characterization of Sentinel Butte Petrified Wood and Host Lithology Associations
… well preserved plant structures including rays, tracheids, and growth rings. These structures were suitable for identifying parent tree type, which was determined to be a gymnosperm. Silica phases involved in the petrification, include microcrystalline quartz (chert), fibrous chalcedony and …

Water Relations of Ponderosa Pine in Contrasting Environments: Implications for Global Climate Change
… that desert trees, because of larger diameter tracheids in the sapwood, had 37% higher rates of water transport per unit sapwood area than montane trees. The combination of low ALAS and higher sapwood conducting efficiency led to two-fold higher hydraulic conductivity (KL), and thus higher …

Effects of environmental factors on wood decay micromorphology of Pinus radiata and Fagus sylvatica, and its significance for in-ground wood preservative performance
… in preservative treated beech fibres and pine tracheids. Whilst some of the micromorphology associated with this type of decay has previously been reported as diffuse type 1 SR, its significance has been largely overlooked. 5. New insights into cavitation decay that forms near or at the S3—S2 …
