Induced changes in the fluorescence of potato and marigold leaves were studied after treating the tubers (potatoes) and spraying the vegetating plants (marigolds) with the growth regulator "Epin-Extra" and the silicon-containing liquid organic fertilizer "Siliplant". The use of these compounds made it possible to compensate for the negative impacts on the photosynthetic apparatus of the plants, associated with the treatment of potato tubers with the fungicide "Maxim" as well as the exposure of marigold plants to a temperature of 5oC for three days. Keywords: potato plant, marigolds, fungicides, epin, siliplant, chlorophyll fluorescence.
