Abstract : B. theobromae grew and sporulated best at 28°C on media amended with ripe mango-extract and dextrose or sucrose. Agar amended with unripe mango pulp caused a reduction in the growth rate. A pink pigment was secreted into the medium, with the highest rate of production at 32°. Inoculation of mangoes with B. theobromae produced infections, especially above 25°, only when fruits began to ripen. Evidence for possible quiescent infection was obtained. The presence of a long pedicel delayed infection by 2-3 d compared with non-pedicellate fruits.
