Reaction Wood
Abnormal wood formed in a leaning tree, often characterized by a dense hard brittle grain and propensity to react irregularly to seasonal moisture changes. In hardwood trees, it forms on the upper side of the lean and is called tension wood. In softwood trees it forms on the lower side of the lean and is called compression wood.
