- •
Se and Sb mutually showed antagonistic effects on their uptake.
- •
Sb and Se showed opposite effects on shoot and root biomass upon exposing to Se.
- •
Se could reduce most root parameters to affect the uptake of Sb.
- •
Sb supply increased the values of most root growth parameters exposing to Se.
- •
SOD, APX and CAT were activated by Se and/or Sb to quench excess ROS.
