Fig. 7

Distribution of Bursaphelenchus xylophilus population in trials I, II, and III. The vertical borders of the box indicate half of all variability in the sample and the center line marks the median value. Lines extending from each box cover the range of remaining data. The dots in the figure indicate outliers. Different letters indicate significant differences between sawdust and stems in different trials of the experiment (mean number of nematodes, MCR test: p < 0.040)
