Environmental effects on the production of Botrytis cinerea conidia on different media, grape bunch trash, and mature berries

摘要

Background and Aims: The presence of viable sources and of conditions favourable for conidial production, dispersal and deposition is essential for a high number of Botrytis cinerea conidia to be available at host infection sites. This study investigated the effect of environmental conditions, growing media and grape organs on the sporulation of ten strains of different genotypes and geographical origin.
