RESUMO

A hydroponics experiment was carried out to study the role of hydrogen peroxide (H2O2) through changes of oxidative stress and antioxidation activity in Salvinia natans Linn. H2O2 is an active oxygen species, widely generated in many biological systems, and mediates various physiological and biochemical processes in plants. In this study, we demonstrated that exogenous H2O2 causes the degradation of pigments and induces the oxidative stress and the antioxidation activity. These effects enhanced with increments of applied H2O2 concentration. Application of polyamine reduced the generation and the accumulation of H2O2 and modulated the enzyme activities.
