An influence of cold hardening (8 °С, 7 days) on the respiration intensity, the content of reactive oxygen species and DNA fragmentation in coleoptiles of maize etiolated seedlings of different ages and a possibility of the cold hardening to prevent execution of the cell death, induced by treatment with 10 mM H₂O₂ (for 4 hours) of seedlings have been studied. It has been shown that H2O2induces total DNA fragmentation in coleoptiles of maize etiolated seedlings, and a preliminary cold hardening prevents this process.

Key words: reactive oxygen species; DNA fragmentation; programmed cell death; coleoptile; Zea mays L.
