Abstract


The aim of this studv was to determine the possibility to infection of apples after harvest by conidia and/or mycelium of Botrytis cinerea Pers. Conidia were unable to infect uninjured apple skin regardless of inoculum density and presence of nutrients. The infection of apples by conidia occurred after the surface wax had been removed by washing of apples with chloroform. Injuries of skin appeared to be a favourable entry point for conidia and mycelium of B. cinerea. Only the mycelium of B. cinerea developed on the apple but not that grown on the artificial medium (PDA) was able to directly penetration uninjured apple skin. It was observed that sometimes rotted spots develo ped arround the lenticels.
