Abstract

In this work, the effect of temperature of incubation on the vegetative growth, sporulation and morphology of the colony of the fungus colletotrichum gossypii South. var. cephalosporioides Costa in substrate containing potato + dextrose + agar pH 5.6, was studied. The experimental design used was that of randomized blocks, with temperatures varying from 12 to 33 degrees centigrades, at intervals of 3°C. It was concluded that the temperature of incubation notably affects the vegetative growth, sporulation and morphology of the colony of this fungus. Temperatures above the optimum range caused greater changes in mycelial, sporulation an morphology of the colony than temperatures below this range. Conidia produced at l2 and 33°C were shown to be shorter than those in other treatments. The temperature of incubation recommended for inocule production was 27°C.
