- Intervention effect Cold stress significantly increased H2O2 and relative conductivity in wheat.
- Intervention effect ABA significantly reduced the cold-induced increase in H2O2 and relative conductivity.
- Intervention effect ABA enhanced cold tolerance in leaves and rhizomes at −10°C and −20°C by increasing CAT, SOD and POD.
- Intervention effect ABA enhanced cold tolerance in leaves and rhizomes at −10°C and −20°C by increasing APX, GR and DHAR.

- Intervention effect At −25°C the ABA-mediated tolerance weakened, with decreased APX, DHAR and MDHAR compared with −10°C and −20°C.
- Observation POD, GR and DHAR levels peaked at −10°C.
- Observation CAT, SOD and GSH content in rhizomes peaked at −20°C.
