The aim of study was to investigate the effect of new growth regulators “Stimpo” and “Regoplant”, produced by State Enterprise Interdepartmental Science and Technology Center − ISTC "Agrobiotech", on the proline and free amino acids content, and lipid peroxidation reactions intensity in comperison to the action of gibberellic acid and “Treptolem” (a second-generation growth regulator) in 14 day sunflower sprouts. The plants were cultured on soil substrates made from the coal mine rock waste of the Central Concentrating Factory in the Chervonohrad mining region. It was shown that the free amino acids and proline content increased, and the intensively of lipid peroxidation reactions (evaluated by the content of malonic dialdehyde) decreased. This indicated to the increase of plants resistance to unfavorable conditions of the coal mine rock under the action of the growth regulators studied. One could assump that “Stimpo” and “Regoplant” are promising agents in phytochemical treatment of coal mine rock dumps.
