RESUMO

In many postharvest fruit diseases, fungi remain latent until the fruit ripens. How the fungus times its infection at ripening of the host is not known. We have found that the volatiles produced by the climacteric tomato, avocado, and banana fruits induce germination and appressorium formation in Colletotrichum gloeosporioides and Colletotrichum musae. Exposure of the spores of these fungi to ethylene, the host's ripening hormone, at
