Exemplary growth curves of one culture vessel containing five A. thaliana seedlings (Trial B) expressed as projected plant area. Projected plant area was calculated as the sum of plant pixels divided by total number of pixels within an image. Yellow smoothed line plot, method = logistic regression, gray indicates confidence interval borders α = 0.95. Six images per day over 16 days resulted in a total number of 96 images per growth curve. Left corner highlights a closeup showing the diurnal rhythm of plant growth. The bottom part contains segmented images of 0, 3, 6, 9, 12, 15 DAT (days after treatment). Time-lapse video of A. thaliana (Trial B) is provided in Additional files 2, 3
