| Abstract: | Summary Crystalline or almost pure organic compounds can be formed either alone or with two or three related compounds in juxtaposition in shakes in central heartwood. The compounds may not always be present in the more complex extractives formed at the heartwood periphery. The largest amounts of deposits are in the innermost or widest portion of the shake. No evidence could be found of a source of substrate, energy or specific enzymes necessary for the selective biosynthesis of these deposits. They are considered to be formedin situ by an undetermined mechanism during enlargement of the shake. |
