Fig. 4From: Hyperspectral imaging to characterize plant–plant communication in response to insect herbivoryAverage reflectance profiles from maize plants divided into four groups, “Control”, “Herbivory”, “Air only”, and “Air and root” (see Fig. 2 for description). Stepwise linear discriminant analysis was conducted to selected spectral bands (black dots), which contributed to the discriminant classification model of Control and Herbivory plantsBack to article page
