When summer comes, adult beetles attack and larva feed in the cambium layer, girdling the trees and sealing their doom.
Later in the season, the cambium becomes firmer and more differentiated, and union of woody parts is more uncertain.
All around the edge of the wound was the cut edge of the cambium layer.
The cells of the cambium are plump little masses of protoplasm, semi-fluid in consistency in the growing season.
But girdle its trunk, exposing a ring of the cambium to the air, and the tree dies.
A Member: Isn't that to keep the wax out of the cambium layer?
Coniferin, C16H22O8, occurs in the cambium of coniferous woods.
The resulting chemical combinations are the sugars and starches used, by the cambium layer in building up the body of the tree.
cambium is an old name of the physiologists for nutritive juice.
The inner portion of the cambium layer is, therefore, nascent wood, and the outer nascent bark.
Plural cambiums or cambia
A cylindrical layer of tissue in the stems and roots of many seed-bearing plants, consisting of cells that divide rapidly to form new layers of tissue. Cambium is a kind of meristem and is most active in woody plants, where it lies between the bark and wood of the stem. It is usually missing from monocotyledons, such as the grasses. ◇ The vascular cambium forms tissues that carry water and nutrients throughout the plant. On its outer surface, the vascular cambium forms new layers of phloem, and on its inner surface, new layers of xylem. The growth of these new tissues causes the diameter of the stem to increase. ◇ The cork cambium creates cells that eventually become bark on the outside and cells that add to the cortex on the inside. In woody plants, the cork cambium is part of the periderm. See also secondary growth.
The layer of a tree where growth occurs, just under the bark.
