Functional and ecological xylem anatomy

Perspectives in Plant Ecology, Evolution and Systematics, 2001
Abstract Cohesion-tension transport of water is an energetically efficient way to carry large amounts of water from the roots up to the leaves. However, the cohesion-tension mechanism places the xylem water under negative hydrostatic pressure ( P x ), rendering it susceptible to cavitation.

Limited effects of xylem anatomy on embolism resistance in cycad leaves

New Phytologist
Summary Drought‐induced xylem embolism is a primary cause of plant mortality. Although c. 70% of cycads are threatened by extinction and extant cycads diversified during a period of increasing aridification, the vulnerability of cycads to embolism spread has been overlooked.

Liana attachment to supports leads to profound changes in xylem anatomy and transcriptional profile of cambium and differentiating xylem

Plant, Cell and Environment
AbstractWood serves crucial functions in plants, yet our understanding of the mechanisms governing the composition, arrangement, and dimensions of its cells remains limited. The abrupt transition from nonlianescent to lianescent xylem in lianas represents an excellent model to address the underlying mechanisms, although consistent triggering factors ...

Water relations and xylem anatomy of ferns

Proceedings of the Royal Society of Edinburgh. Section B. Biological Sciences, 1985
SynopsisThe entire soil-plant-atmosphere continuum must be analysed to elucidate how xylem anatomy relates to water flow in plants. Measurements of water potential gradients and volume of water flow per unit time are needed to obtain values of hydraulic conductance per unit length.

XYLEM ANATOMY AND RELATIONSHIPS OF GOMORTEGACEAE

American Journal of Botany, 1955
THE SYSTEMATIC POSITION and relationships of Gomortegaceae have been uncertain since 1794 when Ruiz and Pavon described the only genus, Gomortega. Most of this dubiety probably has been caused not by the lack of sagacity among those investigators who have studied Gomortega but by the paucity of abundant and complete research material.

Xylem Anatomy Of Diegodendron HumbertΠ

IAWA Journal, 1988
The first description of the wood of the monotypic Madagascan genus Diegodendron is provided. The xylem of D. humbertii is characterised by short , solitary vessel elements with alternate lateral wall pitting and simple perforation plates, imperforate tracheary elements of the libriform fibre type, nearly all biseriate, imperfectly storied, homogeneous
