The annual expansion in the tree is due to the presence of the cambium region that comprises tissue generating cells that are of undifferentiated, embryonic cells. The vascular cambium, between the outer woody tissue and the inner face of the bark, generates living tissues, the xylem on the inner face and the outer phloem. The cambial cells grow beyond the phloem to the phellogen to generate new bark tissue (cork cambium). The rays comprise the living parenchyma cells and their function is to store and mobilise carbohydrates, water, minerals and organic compounds. In some species, rays adapt to form wound-induced, traumatic resin canals like the ‘gum-forming’ response to wounding. Parenchyma also plays an important role in the conversion of sapwood to heartwood to certain wound responses by mobilisation and deposition of exudates and formation of tyloses, resins, gums and other deposits. Hence, when a cut is made leaving a stump projecting some distance beyond the trunk, it delays healing.
