Within the heartwood there are areas <strong>of</strong> wood which are uncolored. These areas are separated by fissures (white lines), which appear to play a role in the inhibition <strong>of</strong> color change. This wood is from the collection <strong>of</strong> the Laboratory for Tree-Ring Research, University <strong>of</strong> Arizona, Tucson.
