Kinetics of Tracheid Differentiation in Douglas-fir

Annals of Botany, 1990
Seasonal cambial activity and the differentiation of tracheids were studied at five stem levels in three crown classes of Pseudotsuga menziesii (Mirb.) Franco (Douglas-fir). Rates and durations of tracheid expansion and secondary wall deposition were computed.

Fluid Self-Diffusion in Scots Pine Sapwood Tracheid Cells

The Journal of Physical Chemistry B, 2006
The self-diffusion coefficients of water and toluene in Scots pine sapwood was measured using low field pulsed field gradient nuclear magnetic resonance (PFG-NMR). Wood chips of 8 mm diameter were saturated with the respective liquids, and liquid self-diffusion was then traced in one dimension orthogonal to the tracheid cell walls in the wood's radial ...

Size and function in conifer tracheids and angiosperm vessels

American Journal of Botany, 2006
The wide size range of conifer tracheids and angiosperm vessels has important consequences for function. In both conduit types, bigger is better for conducting efficiency. The gain in efficiency with size is maximized by the control of conduit shape, which balances end‐wall and lumen resistances.

The nature of pre-Devonian tracheid-like tubes

Lethaia, 1982
In the discussion on early vascular land plants an important part is played by different organic microfossils. One category comprises tube-like objects of pre-Devonian age, called tracheid-like tubes. Recognition of the taxonomic affinity of these microfossils is very important because tracheids are one of the fundamental elements of the xylem and are ...

Wide-band tracheids in genera of Portulacaceae: novel, non-xylary tracheids possibly evolved as an adaptation to water stress

Journal of Plant Research, 2006
Wide-band tracheids (WBTs) are novel tracheids with wide, lignified secondary walls that intrude deeply into the cell lumen when viewed in transverse sections. These tracheids are found in a few genera in related families in the order Caryophyllales: Aizoaceae, Cactaceae, and Portulacaceae. WBTs in these three families vary in (1) systematic occurrence
