Xylem vascular anatomy and water transport of Salicornia europaea

Aquatic Botany, 1993
Abstract The xylem anatomy, changes in vessel member diameter at stem nodes and branch junctions, and effects of these changes on water flow rates and water potential in greenhouse and field grown Salicornia europaea L. (Chenopodiaceae) have been investigated. There was a two-fold decrease in vessel diameter at branch junctions and stem nodes.

Liana Attachment to Supports Leads to Profound Changes in Xylem Anatomy and Cambium and Differentiating Xylem Transcriptional Profile

2023
Wood serves crucial functions in plants, yet our understanding of the molecular regulation governing the composition, arrangement, and dimensions of its cells remains limited. The abrupt change in wood anatomy of lianas represents an excellent model to address the underlying mechanism, although consistent triggering factors for this process remain ...

Functional xylem anatomy of angiosperm trees

1982
Water appears to exist in the xylem of trees under negative pressures for long periods of time, often for years. At the same time, it can move through wood in axial direction with relative ease. This remarkable combination of efficiency and safety is only possible because of the intricate three-dimensional structure of wood.

PEACH TREE VIGOR IS A FUNCTION OF ROOTSTOCK XYLEM ANATOMY AND HYDRAULIC CONDUCTANCE

Acta Horticulturae, 2012
Recently we have demonstrated that there are anatomical differences between dwarfing and vigorous peach rootstocks. These differences in xylem anatomy have been linked to the vigour control capacity of the specific rootstocks. Previously we showed that dwarfing peach rootstocks generally have lower mid-day stem water potentials and that this limits ...

Stem anatomy of Amaranthaceae: Rayless nature of xylem

Flora - Morphology, Distribution, Functional Ecology of Plants, 2002
Summary Secondary xylem of seventeen species from nine genera of Amaranthaceae was studied anatomically. In all these species radial growth in the main stem was achieved by the formation of cambial variants. After cessation of cell divisions in the previous cambium, a new ring of cambium was developed from axial parenchyma cells at a distance of about

Functional xylem anatomy in root-shoot junctions of six cereal species

Planta, 1991
In cereals, the formation of safety zones in the root-shoot junction could protect the vessels of roots from embolism originating in the shoot. The root-shoot junction was examined both anatomically, with a light microscope, and experimentally, using a pressurized-air method, in the base of seminal and adventitious roots of maize (Zea mays L.

The Anatomy of Secondary Xylem and the Classification of Ancient Dicotyledons

1977
The stem wood of about 700 species belonging to 32 families of the order Magnoliales s.l., plus further taxa exhibiting primitive wood anatomical features, was investigated. On this basis, six structural groups can be established each of which show a marked gradation from primitive to advanced stages.

XYLEM ANATOMY AND HYDRAULIC CONDUCTANCE OF COSTA RICAN BLECHNUM FERNS

American Journal of Botany, 1990
Hydraulic conductivities of stems, stipes, and elongate leaf stipes were determined for greenhouse‐grown Blechnum ( B. fraxineum, B. fragile, B. buchtienii, B. sprucei ) and Salpichlaena ( S ...
