Abstract:
Factors known to inhibit sporulation of bio trophic fungal pathogens were found to enhance sporulation of two necrotrophic fungi. The sporulating potential of Stemphyliurn botryosum f. sp. lycopersici on tomatoes and of Alternaria porri f. sp. solani on potatoes increased with necrotization, reaching a maximum on dead leaves. Wetting the dead leaves for the whole period of incubation with increasing concentrations of glucose resulted in progressively decreasing sporulation of both pathogens. However, application of glucose during the first half of the incubation period inhibited sporulation of S. botryosum f. sp. lycopersici on tomatoes only a little, and increased that of A. porri f. sp. solani on potatoes. The capacity of S. botryosum f. sp. lycopersici to sporulate on leaves lasted for 12 weeks at 29°C, and of A. porri f. sp. solani for 12 weeks at 29°C and for over 21 weeks at 20°C. The results emphasized basic differences in sporulation between biotrophic and necrotrophic parasites. Specific techniques useful for studying sporulation in vivo are discussed. © 1975 Springer Science + Business Media B.V.
