Tipburn, an abiotic necrotic breakdown of marginal leaf tissue of iceberg lettuce (Lactuca sativa var. capitata), was consistently induced in field-grown, detached iceberg lettuce heads by high storage temp., e.g., 25 deg C for 7 d or 28 deg for 4 d. However, tipburn was prevented if most stem tissues were removed before the temp. treatment. By contrast, removal of between 14 and 40% of the stem tissue (by weight) did not result in significant (P=0.05) changes in the incidence and severity of tipburn.
