Effects of temperature (OT: 25/15 °C: daytime maximum/nighttime minimum temperature and HT: 35/25 °C) during booting stage on a superoxide radical content (Δ optical density min^− 1 g^− 1), b hydrogen peroxide content (nmol g^− 1), c malondialdehyde content (nmol g^− 1), d cell membrane damage (%), e superoxide dismutase enzyme activity (enzyme units), f catalase enzyme activity (enzyme units), g peroxidase enzyme activity (enzyme units) and h glutathione peroxidase enzyme activity (enzyme units) of wheat genotype Chinese Spring. Values shown are mean ± SE; n = 10 (two experiments and five replications). Vertical bars denote ± S.E. of means. OT, optimum temperature; HT, high temperature
