Abstract : Studies were conducted to evaluate the occurrence of postharvest diseases of 15 mango cultivars cultivated in Pindorama, São Paulo, Brazil, without chemical products. Fruits were individualized and kept in a humid chamber for 24 h, previously at 9 days period at 25±2°C and 70-80% RH. The incidence of postharvest diseases and the severity of anthracnose were evaluated at 3-day intervals. At the beginning of the storage period, the fruits were also characterized as to soluble solids and titratable acidity content. Anthracnose was the main disease in the 15 mango cultivars, with 100% incidence at one day after harvest, followed by stem-end rot, with average among the cultivars of 20.8% at the end of the storage. Smaller anthracnose severity was observed in the Surpresa and Zill cultivars, while smaller incidence of stem-end rot was observed in Winter and Pele de Moça cultivars. Correlation analyses among the soluble solid and titratable acidity parameters of the cultivars with the intensity of the anthracnose and stem-end rot were significant only between acidity and anthracnose, before and after the storage period.
