Characterization of the epidermis of 3 blueberry (Vaccinium corymbosum L.) cultivars and water loss at different storage temperatures.

Fruits of Bluecrop, Blueray and Concord highbush blueberries were classified according to size (large, medium and small). Two sets of each size were selected, one for microscopic study of the epidermis and the other for weight loss determination. Fruits in the second set were stored at 0, 7 and 18 deg C (90-95% RH) until they were unmarketable. The average width of the cuticle was 5 micro m in all cultivars. No relationship was found between cuticle structural features and weight loss of fruits during storage. The most important factors affecting weight loss were the surface:volume ratio of fruits and the storage temperature. Fruits stored at 0, 7 and 18 deg had a storage life of 31, 20 and 10 days, respectively. Scanning electron microscopy found a different structural range of epicuticular waxes in the 3 cultivars. Bluecrop, Blueray and Concord fruits had on average 27.1, 34.7 and 91.4 stomata/mm2, respectively, and in all cases, the stomata were concentrated towards the calycinal cavity of the fruit.
