An Analysis of
Tracheid Length Versus Age in a 4842-year Old ...
Tracheid length responses in relation to wound responses have been
researched, but the wounds are generally caused by pinning – inserting a pin
into a tree. Kuroda (1986) observed an increased rate of cambial divisions after
wounding.

Ecological Strategies of Xylem Evolution
Sherwin John Carlquist. indications from White's data seem clear when
interpreted in terms of ecology. TRACHEID WIDTH Tracheid width might at first
glance seem a potentially important factor in conductive efficiency in ferns.
However ...

Integrative Plant Anatomy
Among these cell types is the tracheid, a long tapering imper- forate cell with
lignified secondary wall thickenings. As noted earlier, in all tracheary elements
the protoplast disappears at maturity. Individual gym- nosperm tracheids range in
...

The fact that not all tracheids are in contact with vessels in these woods that have
undergone tracheid dimorphism should not disqualify use of the term vasicentric
tracheid. In the best-known instance of vasicentric tracheid occurrence (which ...

Wood Structure and Properties '06
RESULTS In our investigation we have focused on wood with regular structure
which consists predominately of tracheid cells (Figs. 1, 2). The symbolic
representative is spruce (Picea spp.). The least structural member was tracheid.
This type ...

Testa characters in tribe Vicieae, with notes about tribes ...
A tracheid bar is always present, extending the length of the hilum just beneath
the hilar groove. This bar is always embedded in a mass of rather spongy
parenchyma, which forms a thicker layer here than elsewhere in the seed (figs.

Nels R. Lersten, Charles R. Gunn, United States. Agricultural Research Service, 1982
The presence of tracheary elements is the defining characteristic of vascular plants to differentiate them from non-vascular plants. Tracheid build varies by location.

Resource Physiology of Conifers: Acquisition, Allocation, ...
However, the conifer tracheid appears to be quite resistant to permanent
dysfunction as caused by embolism, as will be described below. There is
variation among conifer species in the structure of the pit membrane (Bauch et al.
, 1972).

Water Transport in Plants Under Climatic Stress: Proceedings ...
It was shown theoretically that up to 8% of the water in each tracheid lumen may
migrate through a single tangential wall of a freezing tracheid (Robson & Petty,
1987). Fig. 1 shows three possible routes for water migration from a freezing ...
