Discoloration & decay in oak

Abstract

Diseases that result in discoloration and decay of wood are major problems affecting all species of oak. Wounds often start the processes that can lead to these diseases. The type and severity of the wound, the vigor of the tree, the environment, and the aggressiveness of microorganisms that infect are some of the most important factors that determine the nature of the disease. Decay following fire wounds and decay in sprout stems have been the major defects in oak. Now discolorations and other defects once considered minor are becoming more important.
