Differential exposure to field solar radiation and postharvest chilling injury of cantaloupe melons.    Sensitivity to chilling injury (CI) of Cucumis melo var. cantalupensis varies from slight to severe, depending o­n cultivar, and limits temperatures to be used during storage depending o­n conservation period.Previous studies in other fruits, including C. melo var. inodorus cb. Honey Dew, have shown a close relationship between exposure to solar radiation in the field and postharvest CI of fruits.In these studies carried out at an intermediate latitude (32° 25’S), the highly sensitive cantalupensis cv. Colima was sown sequentially, from early to late spring, and fruits tagged at anthesis were left uncovered, shaded with a 50% shading mesh or partially covered with sunlight excluding bags.Fruits harvested at different dated during the summer were stored for 14 days at + 1 °C, plus 3 additional days at 20 °C, and rated for CI symptoms.Results demonstrated highly significant effects of incident solar radiation o­n CI expression.Although ratings varied according to total accumulated solar radiation, fruits exposed to direct sunlight showed higher CI and, o­n a given fruit, sun exposed areas were most affected.
