Key words: supercritical fluid extraction, Reynoutria sachalinensis, slow fluorescence induction, thermoluminescence

The effect of supercritical fluid (SF)  extracts of giant knotweed Reynoutria  sachalinensis on photosynthetic  activity of Vicia faba L. bean leaves was studied by slow  fluorescence induction (SFI) and thermoluminescence (TL) methods. The treatment  of plants        with extracts led to the enhancement of  their photosynthetic activity. The maximum stimulating effect was observed for  extract obtained using carbon dioxide with 2% of ethanol as co-solvent. The  observed stimulating effect is assumed to be bound with        increasing of carries pool of the  photosynthetic electron transport chain of plant leaves by quinonic compounds  flux into plant cells.
