Non-invasive observation of the development of fungal infection in fruit

Summary The progression of infection caused by a fungal pathogen,Botrytis cinerea Pers.: Fr., in a fruit of red raspberry (Rubus idaeus L.) was followed by nuclear magnetic resonance (NMR) microscopic imaging over a 4 day period. It was found that a standard gradient echo sequence discriminated clearly between infected and healthy tissue as mycelium spread across the fruit from a single woundinoculated drupelet.
