Fig. 4
From: Nutritional and genetic variation in a core set of Ethiopian Tef (Eragrostis tef) varieties
Levels of 12 phenols identified in the flours of 24 tef varieties. Each box shows the range of concentrations in μg/g of 12 phenolic compounds measured in the 24 tef varieties. The box defines the upper and lower quartiles. The lines extending vertically, “whiskers”, indicate variability outside the upper and lower quartiles, with points outside those lines, represented by dots, being considered outliers
