Fig. 7From: Characterisation of early responses in lead accumulation and localization of Salix babylonica L. rootsMicrographs of S. babylonica roots using Leadmium Green AM dye at longitudinal sections of roots exposed to different Pb concentrations (0, 1, 10, 50, or 100 μmol/L) for different treatment times (3, 6, 12, and 24 h). a1–d1: Control without Pb for 3, 6, 12, and 24 h; a2–d2: 1 μmol/L Pb for 3, 6, 12, and 24 h; a3–d3: 10 μmol/L Pb for 3, 6, 12, and 24 h; a4–d4: 50 μmol/L Pb for 3, 6, 12, and 24 h; a5–d5: 100 μmol/L Pb for 3, 6, 12, and 24 h.
