NOT PEER-REVIEWED
"PeerJ Preprints" is a venue for early communication or feedback before peer review. Data may be preliminary.

Supplemental Information

Data of plant biomass, Tls, root/shoot ratio were determined and the relation between Cd concentration and inhibition rate of root or shoot biomass were also determined

Raw data were applied for data analyse of biomass, Tls inhibition and preparation for Table1 and Table2

DOI: 10.7287/peerj.preprints.2883v1/supp-1

Cd uptake, the distribution proportion of Cd and Cd bioconcentration factors in root response to Cd

DOI: 10.7287/peerj.preprints.2883v1/supp-2

Nutrient elements uptake in root and shoot were determined under Cd stress

Raw data were applied for data analyses of metal uptake and preparation for Figure 3.

DOI: 10.7287/peerj.preprints.2883v1/supp-3

Pigment content of Italian ryegrass response to Cd

Raw data were applied for data analyses of correlation among root Tls, Cd uptake in root, TFs, MDA content of root, NPT content of root and preparation for Table 4.

DOI: 10.7287/peerj.preprints.2883v1/supp-4

The correlation among some physiological index were analysed

Raw data were applied for data analyses of correlation among root Tls, Cd uptake in root, TFs, MDA content of root, NPT content of root and preparation for Table 4.

DOI: 10.7287/peerj.preprints.2883v1/supp-5

MDA and NPT content of Italian ryegrass response to Cd

Raw data were applied for data analyses of MDA and NPT and preparation for Figure 4 and Figure 5.
