Response of the vascular cambium to reorientation in patch grafts

Canadian Journal of Botany, 1976
The vascular cambium was reoriented in square 5-mm panels of bark at 90° and 180° from the normal position in three varieties of Malus baccata and Malus sylvestris (ornamental crabapple), Cornus stolonifera, Sorbus aucuparia, and Thuja occidentalis, Douglasii pyramidalis. Panels grafted in the normal orientation served as controls.

Studies on the vascular cambium

1974
The nature of the vascular cambium is discussed and the length of the elements in the secondary xylem related to the division and elongation cycles of the cambial fusiform initials. Particular attention is given to the activities of the storeyed cambium. The ontogeny of the storeyed cambium is described for Hoheria angustifolia Raoul. (Malvaceae).

THE ONTOGENY OF THE VASCULAR CAMBIUM IN THE STEM OF SEED PLANTS

Biological Reviews, 1965
Summary1. A striking characteristic of the vascular cambium is its plasticity. It may arise in any position in any tissue except the epidermis. It may function in a variety of ways, giving rise to xylem or phloem alone, or to both tissues. If both xylem and phloem are formed from the same cambium, they may be derived from opposite faces of the meristem

The vascular cambium: structure and function

2010
Perspective It is difficult to overemphasize the importance of the vascular cambium which produces secondary xylem and secondary phloem. In the following two chapters we shall discuss in detail the structure, functions, and the importance to the plant of these tissues which also have great significance for mankind.

The ontogeny of the vascular cambium inGinkgo biloba roots

The Botanical Magazine Tokyo, 1988
Observation was made on early ontogeny of vascular cambium in the developing root ofGinkgo biloba L. After completion of root elongation, the vascular meristem gradually acquires cambial characteristics. Strips of the periclinal division of cells in transverse section are observed on the inner side of phloem when the primary xylem and phloem in the ...

Defect coarsening in a biological system: The vascular cambium of cottonwood trees

Physical Review E, 2003
We present micrographic evidence for the annihilation of topological defect pairs and defect-mediated coarsening in the vascular cambium of cottonwood trees (Populus deltoides). We also show that a recently published mathematical model of cell orientation dynamics in the cambium reproduces many qualitative features of the defect coarsening process.

A Mathematical Model of Pattern Formation in the Vascular Cambium of Trees

Journal of Theoretical Biology, 2002
The beautiful patterns apparent in wood grain have their origin in the alignment of fusiform initial cells in the vascular cambium of trees. We develop a mathematical model to describe the orientation of fusiform initial cells, and their interaction with the plant hormone indole-3-acetic acid (auxin).

DEVELOPMENTAL CHANGES IN THE VASCULAR CAMBIUM IN LEITNERIA FLORIDANA

American Journal of Botany, 1967
Developmental changes in the vascular cambium of Leitneria floridana, a shrub, were determined primarily by an analysis of the secondary xylem. During the production of the first growth ring of secondary xylem, 37% of the anticlinal divisions in the fusiform initials were lateral, the remaining were oblique.

Molecular Control of the Development and Function of the Vascular Cambium

2000
In woody species, the primary growth associated with shoot and root elongation is followed by secondary growth that increases the radial width of xylem and phloem through the activity of the vascular cambium. This meristem is similar to the shoot and root apical meristems in exhibiting highly controlled patterns of cell division, with individual ...
