Preharvest conditions and postharvest treatments affecting the incidence of decay in mango fruits during storage.

The quiescent infected area (QIA) by Alternaria alternata, the cause of black spot on mango fruit at harvest, was closely related to the number of hours with RH more than or equal to 80% during a 52-day-period of fruit development. At least 350 h of RH more than or equal to 80% during the fruit-growing period was necessary for significant incidence of disease. A map of average daily maximum RH during fruit growth can be used as a basis for predicting the incidence of black spot in Israel. The presence of antifungal, 5-substituted-resorcinols in fruit peel had been reported to affect the quiescent infection by A. alternata. Treatments with 35% carbon dioxide for 24 hours at 20 deg C enhanced the level of antifungal compounds and delayed decay development.
