In all organisms are rising a reactive oxygen and nitrogen species by the effects of various stress factors and these species have a negative impact on the organism. Due to this species plants have built up an efficient antioxidant system, that helps them to resist negative effects of reactive oxygen and nitrogen species. In this work was researched the effect of hydrogen peroxide and sodium benzoate on the production of hydrogen peroxide, superoxide, reactive nitrogen species and malondialdehyde, contained in the root and above-ground part of maize (Zea mays L.). By use of the fluorescence microscopy there were obtained images of cross-cut of root from which was determined the intensity of fluorescence of individual parts of the root and was examined the effect of the intensity of fluorescence markers of oxidative stress in dependence on the type of the fluorescence filter used.
