Research Concerning the Setting and Development of Rot within Wounds at Beech Trees

Abstract

The wounds inflicted on standing trees are lesions constituted by tissue damage and dislocations of wood anatomical elements, caused by striking, frost, and blazes. Their cicatrization is the result of cambium activity which generates callus tissues in the form of healing waves. Callus tissues on the brink of the wound develop rapidly in a tangential and then radial direction, which allows the wound to close with the increase of the tree circumference. The cicatrization time, the infestation of wounds, and the spreading of pathogen agents inside the tree depend on the influence of the following factors: location, size, age, depth, and form of wounds.
