From: Coronilla juncea, a native candidate for phytostabilization of potentially toxic elements and restoration of Mediterranean soils

Figure 2

Relative root biomass (mean ± standard deviation) i.e. ratio of the dry root biomass of Coronilla juncea vs. dry soil mass at different soil depths and sites. Means are expressed in gram of dry roots per kg of dry soil. Different letters indicate a significant difference between means (p-value ≤ 0.05). Sites: S = reference site at Sormiou. E1 = Escalette 1 and E2 = Escalette 2.
