Symptom development and color analysis of pericarp and columella discs after 4 days of storage. The top images (a) show pericarp discs from the blossom-end (rows 1 and 3) and stem-end (rows 2 and 4) of a total of 4 fruit. Within each image, rows 1 and 2 contain discs from the same fruit, and rows 3 and 4 contain discs from the same fruit. No fruit were showing blossom-end rot symptoms prior to disc preparation. Columella discs from two fruit (b) were arranged with the disc taken from closest to the stem-end on the left and each subsequent disc being taken from closer to the blossom-end. Colorimetric measurements were made on the pericarp discs shown above (a) on day 4 of storage. Each point represents an individual disc, and data labels indicate the visual BER rating at the time of color measurement. Pericarp color of healthy stem-end tissue and BER affected blossom-end tissue was measured on 4 whole fruit that developed BER on the plant (d)
