Factors affecting postharvest infection of stored cabbage tissue by Botrytis cinerea

Abstract: Single-spore isolates of Botrytis cinerea from commercially stored cabbage exhibited a broad range of virulence. Spore germination and hyphal growth required an exogenous source of nutrients. The ability of either spores or mycelium to cause infection of stored cabbage tissue was also dependent upon exogenous nutrients. Nutrients required for infection could be supplied in the form of glucose, cabbage leaf extract, potato dextrose agar (PDA), or by a wound at the site of inoculation. The concentration of nutri… Show more

“…The fact that isolates of P. savastanoi obtained at different times of the year differed in several cultural, physiological and biochemical characters also suggests that the relative efficiency of the bacteria in utilizing the leaf surface as a substrate for growth and survival may be an important factor in this respect. Material originating outside the leaf may improve the nutrient value of the phylloplane for some micro-organisms (Fokkema, 1971;Yoder & Whalen, 1975;Clark & Lorbeer, 1976), but a significant role for pollen on the phylloplane of the olive does not seem likely as control experiments resulted in a lower recovery of bacteria from olive leaves in May, when the olive and most grasses were flowering in the area, than in April. A similar conclusion was reached by Dickinson et al (1975) in their study of phylloplane bacteria from Lolium perenne.…”

“…1958, ELLIS andWALLER 1974) or else the most important agent causing losses during storage (STRUC and CRUTZ 1972, BROWN et al 1975, BOCHOW et al 1976, LOCHART 1976, KEAR et al 1977, SEIDEL and BARESEL 1978. The losses can be as high as about 25-40 %of the stored crop (YODER andWHALEN 1975, KEAR et al 1977). Other storage pathogens of cabbage, which are important in cases where the harvesting conditions are warm and damp or in stores other than refrigerated ones at O°C, are as follows: Alternaria spp.…”

“…As temperaturas mais propícias para o progresso de doenças do gênero Botrytis nesses estudos estão entre 12 e 25°C (1, 4, 12,13,19,22,24,29,30). Sendo assim, nenhum trabalho relata altos índices de incidência e de severidade de doenças causadas por espécies do gênero Botrytis, para condições de temperatura superiores a 25°C, como observado neste trabalho para o gênero Amphobotrys.…”
