Other claims from this paper (8)
- Intervention effect Ozone and drought hardening before copper treatment significantly increased tolerance of spring barley seedlings to copper.
- Mechanism Cross-adaptation to copper is most probably caused by increased CAT activity, mitigation of O2˙− accumulation and lipid peroxidation in spring barley.
- Observation Copper treatment triggered very strong oxidative stress in nonhardened spring barley seedlings.
- Intervention effect Cadmium cross-adaptation in spring barley was induced only by drought hardening.
- Intervention effect Drought-hardened barley had a lower effect on antioxidative enzymes during cadmium cross-adaptation.
- Intervention effect Drought-hardened barley slightly increased the intensity of lipid peroxidation during cadmium cross-adaptation.
- Mechanism Stimulation of CAT activity and mitigation of oxidative stress are the main reasons for copper adaptation in spring barley.
- Mechanism Cross-adaptation to cadmium in spring barley is determined by mechanisms not directly related to oxidative stress.
