HE BEHAVIOR OF THE FUNGUS Colletotrichum gossypii South. var. cephalosporioides Costa IN SUBSTRATE CONTAINING DIFFERENT SOURCES OF CARBON.
ln this experiment. the behavior of Colletotrichum gossypii South. var. cephalosporioides Costa. in a solid substrate containing different sources of carbon, was attempted to be determined, the vegetativa growth, intensity ot sporulation, size of the conidia, were measured and the morphological characteristics of the colony were described. A sinthetic substrate was used as the basic medium, and to this, the source of carbon, according to the treatment (maltose, dextrose, lactose, starch, saccharose and galactose), was added. lt was concluded that the dextrose produced a greater vegetative growth in the colonies, but the starch produced greater intensity of sporulation. The galactose seemed to have exercised a harmfull effect on the development of the fungus, stimulating the formation of small colonies, atypical and the tew conidia produced exhibited shorter length than the conidia tormed in the other tested substances. There
was no correlation between the intensity of sporulation and the size of conidia, nor between the vegetativa growth and intensity of sporulation.
The composition of the substrate aftected profoundly the colar, the shape, the aspect, the periphery and the topography of the colony.
