DescriptionThis paper describes increment cores (a useful tool in forestry and wood technology) and their uses which include age determination, growth increment, specific gravity determination, fiber length measurements, fibril angle measurements, cell measurements, and pathological investigations. Also described is the use and care of the increment borer which is essential in obtaining good cores. A caution is also given as to the tree damage that boring can cause, with suggestions for minimizing damage.
