Abstract

Botrytis blight caused by the fungus Botrytis cinerea is probably the most common disease of greenhouse-grown crops like tomato. Botrytis blight in tomato plants is mainly detected by visual inspection or destructive biochemical and molecular determinations. These methods are time consuming and not suitable for large sample sizes. In contrast we propose a non-destructive detection method for plant diagnosis using volatiles as early indicator of plant diseases. This paper presents the changes in volatile production during an infection of tomato plants by B. cinerea. Volatile emission from tomato plants before and after inoculation with B. cinerea were analyzed using on-line gas chromatography coupled to mass spectrometry. The emission was monitored from 2 to 72 hours after inoculation with a time resolution of 1 hour. The data was subjected to principal component analysis for fast interpretation of the variation between samples. Results show that infected plants produce different number and amounts of volatile metabolites compared to control plants. The emission did not only depend on the stage of infection, but also on the diurnal rhythm of the plants. Further research is required to determine the uniqueness of the volatile pattern of B. cinerea infected tomato plants. If so, then, disease specific compounds could be used as early indicator for B. cinerea detection in greenhouse crop production
