The ontogeny of the vascular cambium inGinkgo biloba roots
The Botanical Magazine Tokyo, 1988Observation 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 ...

Developmental changes in the vascular cambium ofDelonix regia Rafin
Proceedings / Indian Academy of Sciences, 1981The developmental changes occurring in the vascular cambium ofDelonix regia have been studied in different age group trees having different circumferential central axis. It has been found that the cambial cells undergo considerable variation both in their number and dimension with the growing age.

On the origin of vascular cambium in dicotyledonous stems
Proceedings / Indian Academy of Sciences, 1980The present paper reviews the relationship between the procambium and the vascular cambium. It is suggested that the procambium is not a pre-requisite for the formation of vascular cambium, even in the stems, as is claimed by several morphologists.

Studies on the vascular cambium
1974The 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 vascular cambium: structure and function
2010Perspective 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.

DEVELOPMENTAL CHANGES IN THE VASCULAR CAMBIUM IN LEITNERIA FLORIDANA
American Journal of Botany, 1967Developmental 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.

Response of the vascular cambium to reorientation in patch grafts
Canadian Journal of Botany, 1976The 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.

Early ontogeny of vascular cambium II.Aucuba japonica andWeigela coraeensis
The Botanical Magazine Tokyo, 1974InAucuba andWeigela the six vascular bundles distributed as a hexagon become connected tangentially by meristematic cells into a procambial cylinder in the early stage. In the tangential view, the procambial cylinder shows a rather homogeneous structure.

DEVELOPMENTAL CHANGES IN THE VASCULAR CAMBIUM OF POLYGONUM LAPATHIFOLIUM
American Journal of Botany, 1969Developmental changes in the vascular cambium of Polygonum lapathifolium were determined primarily by an analysis of the secondary xylem. The cambium and xylem consist of fascicular and interfascicular regions in this herbaceous dicotyledon. Near the pith vessels are restricted to the fascicular regions of the xylem. During secondary growth vessels are

THE VASCULAR CAMBIUM AND XYLEM DEVELOPMENT IN HIBISCUS LASIOCARPUS
American Journal of Botany, 1963Cumbie, B. G. (U. Missouri, Columbia.) The vascular cambium and xylem development in Hibiscus lasiocarpus. Amer. Jour. Bot. 50(9): 944–951. Illus. 1963.—Circumferential growth of the vascular cambium, as determined primarily by an analysis of the secondary xylem, in Hibiscus lasiocarpus, an herbaceous dicotyledon, occurred through both radial and ...
