During 1989, leaves of 3 cultivars of Acer saccharum were sampled from a cultivar trial. The purpose was to anatomically investigate development of leaves and incidence of foliar injury due to tatter. Previously, certain cultivars had been observed to be more predisposed to tatter than others. However, more injury symptoms than just tatter occurred. An extensive literature search revealed that definitions for each type of injury varied and often conflicted.

In this poster, photographs of various injuries plus the terms and definitions deemed most representative of what was observed will be presented. Terms explored will include tatter, windburn, sunburn, scorch and scald. Also, a separate symptom which may prompt creation of a new term. will be presented. This injury appears to be part of, but could be separate from, the etiology of leaf tatter. This new term must be considered carefully as preliminary results suggest that tatter does appear to be linked to anatomical differences among cultivars. A questionnaire soliciting opinions/reactions to the confusion in the literature, these terms, and the new term(s) will be featured. Hopefully, this will help resolve the leaf injury nomenclature dilemma.
