Cultivation of qualitative planting material involves optimal extra nutrition conditions, which requires understanding of biochemical and physiological processes associated with seedlings adaptation. A reliable integral indicator of plants viability is plastidial pigments composition, oxidoreductases activity, secondary metabolites synthesis, including phenolic compounds of pigmental complex. Research results of water-soluble fertilizers “Harmoniya”, “Rozsada-start” and “Novofert-Universal” on phenolic substances content in pine seedlings needles in their extra nutrition different conditions are given. Peculiarities of phenolic compounds synthesis, content and ratio of plastidial pigments in Scots pine seedlings needles under water-soluble fertilizers influence are shown.
