Fifty-six disks cut at random from the stumps of 880 Elberta peach trees (Prunus persica) showed evidence of 131 wounds. The trees had been pulled because of poor production. Discolored and decayed wood associated with the wounds was compartmentalized according to the CODIT (compartmentalization of decay in trees) model for tree decay. Disks with a high percentage of infected area had narrower widths of sapwood than did disks with a low percentage of infected area.
