Abstract

Triticale seeds with different content of selenium (Se) were germinated and Se remobilisation into above ground part of plants and its effects on dry matter of seedlings were investigated. The activities of superoxide dismutase, catalase, peroxidase and gluthatione peroxidase, soluble protein content, lipid peroxidation and accumulation of reactive oxygen species were also measured. The oxidative stress found at the elevated Se content resulted in reduced dry matter, increased reactive oxygen species production and altered activities of all measured enzymes. This result indicates that the remobilisation of Se from seed tissues during germination and early growth in seedlings was intensive and that toxicity of Se can be attributed to its pro-oxidative effects in triticale plants.
