Application Note: Measurement of Biophoton Emission in Plants –An Alternative Monitoring System for Stress Factors
5 July 2012

Biophoton emission (BE) or autoluminescence imaging is a method to measure stress status of plants in a non-invasive way similar to delayed fluorescence. Both are extremely weak light emissions which can be used to monitor the physical state of a plant. This application note shows the difference between both methods and state parameters to perform these measurements using the NightSHADE plant imaging system.
