The photochemical activity, pigment composition, and activity of antioxidant enzymes of sunflower leaves under the action of biologically active substances were analyzed. Significant inhibition of the chlorophyll a and b content was established in samples 2 and 3 of the variant and it increased in the leaves of the 5th variant. A significant decrease in catalase with an increase in the peroxidase activity of leaf tissues was revealed in all variants. Analysis of the FCI of the leaves showed growth in carbon assimilation in the leaf’s sunflower of the 5th variant with a decrease in this indicator in all other experimental variants.
