Assessing the biodiversity and the impact of pollinators on carob production

Fig 5. Carob pod number (A), weight (B), length (C), and seeds per pod (D) in the open and wind pollination treatments in the three regions. Boxplots show the median for each treatment, box boundaries show the 25th and 50th percentile, while whiskers extend to 1.5 times the interquartile range (IQR). Points beyond 1.5 times the IQR are plotted individually. Diamonds show the mean. Individual data points are shown with blue triangles. Horizontal jittering was used to allow visualization of all data points. https://doi.org/10.1371/journal.pone.0291431.g005 Table 4.
