Fig. 3

Box-and-whiskers plots representing the estimated damaged area (mm2) obtained from each of the systems under different lighting conditions and white (top row) and black (lower row) backgrounds. Data were obtained from A. thaliana Col-0, Bla-2 and Kon genotypes, infested with 20 T. urticae adults for 4 days; n = 8. Lighting conditions (brightness, contrast for each case): w2 and b2 (central column) = Automatic threshold (30,-20 White; 40,-10 Black); w1, w3, b1 and b3 values were selected for each background subtracting and adding 10 values of brightness, respectively, maintaining contrast values. Black dots indicate outlier values
