Figure 8

Correlation between Cr uptake in different parts of the plant and some selected traits of morphological attributes, photosynthetic efficiency, oxidative stress and response of antioxidant enzymes, nutrient uptake, and organic acid exudation pattern. Different abbreviations used in the figure are as follows: SOD-R, superoxidase dismutase activity in the roots; Pro, proline content; POD-R, peroxidase activity in the roots; Phe, phenolic content; EL-R, electrolyte leakage in the roots; FA, fumaric acid content; OA, oxalic acid content; Cr-S, chromium content in the shoots; MDA-R, malondialdehyde content in the roots; Cr-R, chromium content in the roots; Ca-R, calcium content in the roots; Fe-R, iron content in the roots; SS, soluble sugar content; SL, shoot length; NOL, number of leaves; RDW, root dry weight; TC, total chlorophyll content; TR, transpiration rate.
