The aim of the research was to identify quantitative changes in the processes of photosynthesis and fatty acid composition of the maize plants vegetative mass during ontogenesis and under the influence of mineral fertilizers and growth regulators. It is established that the functional activity of the photosynthetic apparatus in the leaves of maize plants increases with their age and depends on soil fertilizer and the influence of growth regulators. It was found that the increase in the functional activity of the photosynthetic apparatus of maize plants in the phase of intensive growth is accompanied by an increase in the concentration of esterified fatty acids and an increase in the ratio of more valuable linolenic polyunsaturated fatty acid to less valuable linoleic polyunsaturated fatty acid in stems and leaves. It is established that the formation of generative organs of maize plants leads to a gradual decrease in the concentration of esterified fatty acids and a decrease in the ratio of linolenic polyunsaturated fatty acid to linoleic polyunsaturated fatty acid in the stem and leaves.
