While wider tracheids with robust walls make it possible to achieve higher water transport pressures, this increases the problem of cavitation.
22.
For this reason, pits in tracheid walls have very small diameters, to prevent air entering and allowing bubbles to nucleate.
23.
The tracheids of earlywood formed at the beginning of a growing season have large radial sizes and smaller, thinner cell walls.
24.
Tracheid length might be slightly shorter than either parent, even though tracheid length in southern pines usually does not differ significantly.

Now, that fine-ground mass, under magnification, is a series of disaggregated tracheids _ water-conducting plant cells.
27.
The structure of the tracheids in the long lateral roots of white spruce varies with soil nitrogen availability ( Krasowski and Owens 1999 ).
28.
Tracheids also have pits, but only vessel elements have openings at both ends that connect individual vessel elements to form a continuous tubular vessel.
29.
Damage to a tracheid's wall almost inevitably leads to air leaking in and cavitation, hence the importance of many tracheids working in parallel.
