Abstract
Preharvest cuticular fractures in sweet cherry fruits have been suggested to facilitate pathogen invasion.
Grey mould caused by the fungal pathogen Botrytis cinerea is an important pathogenic fungi in Norwegian sweet cherry orchards.
The pathogen is known as a weak parasite prefering wounds or weakened tissue as infection sites.
A method for classifying the amount of cuticular fracturing on sweet cherry fruits into five categories has been suggested.
Sweet cherry fruits of cvs.
Vista and Van were sorted into these five categories and inoculated with a conidial suspension of B. cinerea. After storing the fruits at 20°C and 100% RH for 4–7 days, they were assessed for visible pathogen infections.
A high correlation between the amount of cuticular fracturing and visible fungal infections was obtained, indicating that fungal infection in sweet cherry fruits is facilitated by cuticular fractures.
