Superweakbiochemiluminescence (SBL) and oxygen absorption in plant roots of 5-6-day sprouts of monocotyledonous and dicotyledonous plants have been studiedin the present work. SBC registration of sprouts was carried out by means of quantometric device and the measurements of О2 absorption – by polarographic aggregate. The advantage of a SBC method is:it allows obtaining accurate information on intracellular oxidation processes not bringing any fluctuations in development of chemical reactions and their coordination in cells.It was ascertained that inserted sprouts Сu2 + ions into root system effectively participate in catalytic decomposition of the hydroperoxide formed in lipid phase of biomembranesas a result of auto-oxidizing reactions. The decomposed hydroperoxides initiate more active radicals of RO and OH types that interacting with KCN they promote sharp increase of a luminescence intensity correlating as О2 absorption by sprouts increase.
