Web12. apr 2024 · The use of inducers of systemic acquired resistance (SAR) is widely described in the literature. Such substances have important advantages over plant protection products (PPPs) and, thus, are often indicated as their alternatives. The main risk indicated in the context of the widespread use of SAR inducers is that of yield reduction that may result … WebAn oxidation–reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction.

Webreduction: a decrease in the number of oxidation of a chemical species, generally due to an acquisition of electrons by the species. Reduction: oxidizing species + n e- → reduced species. Oxidation: reducing species → oxidized species + n e-. being n the number (or moles) of electrons exchanged during the reaction, equal in both half-reactions.
