Abstract
Increment cores that dry with a spiral twist are a problem in any study where a clear view of transverse wood anatomy is required. This problem may become acute when working with wood that is partially decomposed. After soaking cores in a urea solution, we can remove spiral twists by applying steam to the cores and gently twisting cores until they straighten. Treatment does not result in a serious distortion of ring widths.
