Wood anatomy is a scientific sub-area of wood science, [1] which examines the variations in xylem anatomical characteristics across trees, ... (called also as ...
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants.It is an organic material – a natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression.
InsideWood is an online resource and database for wood anatomy, serving as a reference, research, and teaching tool. Wood anatomy is a sub-area within the discipline of wood science . [ 1 ] [ 2 ] This freely accessible database is purely scientific and noncommercial.
Wood physics, which constitutes an essential component of the field of wood science, building upon discoveries in wood chemistry, wood anatomy (xylem), and biology, as well as principles from classical physics, mechanics, and materials strength. [14]
Branch attachment in common ash Fraxinus excelsior L. Figure 1: Anatomical drawing of the wood grain of a branch attachment in a tree. Initially branches are mechanically attached to the trunks of trees by forming interlocking wood grain patterns at the top of the joint, within what is known as 'axillary wood' (Fig. 1). [1]
Wood Sapwood (alburnum) Heartwood (duramen) Pith (medulla) In young stems, which lack what is commonly called bark, the tissues are, from the outside to the inside: Epidermis, which may be replaced by periderm; Cortex; Primary and secondary phloem; Vascular cambium; Secondary and primary xylem.
Also called pith rays or wood rays, these formations of primarily parenchyma cells allow the radial transport of sap and are essential in the process of tylosis. [ citation needed ] In quartersawn material, where the wood is cut into boards with the growth rings roughly perpendicular to the face of the board, the medullary rays often produce ...
These products are produced by the cambium and transported to the centre of the stem by cellular structures called medullary rays radiating from the center of the stem [5] and then enter living axial paratracheal parenchyma cells. As the wood ages, the contents of the parenchyma cell burst into the dead vessel through the pit linking the two.
