Temporal Dynamics of Septoria Leaf Spot of Blueberry and its Relationship to Defoliation and Yield

Fig. 5. Box-whisker plots showing the distribution of Septoria leaf spot severity values on shoots of Premier rabbiteye blueberry that subsequently formed different numbers of flower buds in field trials in Athens, Georgia from 2001-2002 to 2003-2004. Disease severity is expressed as the number of spots per leaf prior to defoliation of that leaf and averaged for all leaves on a given shoot. The boxes represent the interquartile range, with the whiskers indicating the 5 and 95 percentiles. Lines and circles within the boxes represent median and mean disease severity values, respectively.
