PREHARVEST CONDITIONS AND POSTHARVEST TREATMENTS AFFECTING THE INCIDENCE OF DECAY IN MANGO FRUITS DURING STORAGE

D. Prusky, I. Kobiler, G. Zauberman, Y. Fuchs
The quiescent infected area (QIA) by Alternaria alternata, cause of black spot, on mango fruit at harvest was closely related to the number of hours with RH ≥80% during a 52-day-period of fruit development. At least 350 h of RH ≥80% over 320 increased. 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 the preformed, antifungal, 5-substituted resorcinols in fruit peel was reported in the past to affect the quiescent infection by Alternaria alternata. Treatments with 35% CO2 for 24 hours at 20°C enhanced the level of antifungal compounds and delayed decay development.
