Fig. 4From: Phenotypic differentiation and diversifying selection in populations of Eruca sativa along an aridity gradientBox-plot showing variation in plant fitness related traits in the Mediterranean (EG), semi-arid (BS) and desert (SA) populations of E. sativa (N = 10 for each population): A Root dry weight (g); B Shoot dry weight (g); C Total number of fruits; and D Total seed weight (g); (○) presents outlier values. Different letters above each box represent significant differences (ANOVA Tukey post-hoc range test, P < 0.05)Back to article page
