Thermal and chlorophyll-fluorescence imaging distinguish plant-pathogen interactions at an early stage

Different biotic stresses yield specific symptoms, owing to their distinct influence on a plant's physiological status. To monitor early changes in a plant's physiological status upon pathogen attack, chlorophyll fluorescence imaging (Cnl-FI) and thermography, which respectively visualize...
