Root density in A. bisulcatus and M. sativa (both of Fabaceae family). (a,d) control/control treatment; (b,e) control/selenite (30 mg kgDW−1) treatment; (c,f) control/selenate (30 mg kgDW−1) treatment. Reported percentages are the average of 8 biological replicates for each treatment (n = 8). Root density data were not significantly different among the two halves after Student’s/Wilcoxon Rank Sum Tests (p < 0.05) (n = 8).
