The influence of the Regoplant and Stimpo on the activity of antioxidant protection enzymes in the Helianthus annuus L. and Brassica napus L. grown on the substrations of the wet recovery of coal mine

Abstract

The influence of optimal growth rates of G.A. and new growth regulators of Stimpo and Rйgoplant on the activity of antioxidant protection enzymes – peroxidase, catalase and polyphenol oxidase, as well as the content of hydrogen peroxide and phenols in the seedlings of Helianthus annuus L. and Brassica napus L. due to their growth on extracts from the substrates of the waste heap of coal mines. At influence the studied regulators on plants revealed increased activity of peroxidase, decreased activity of catalase and polyphenoxidase and increased content of hydrogen peroxide. The content of phenolic compounds decreased due to increased activity of peroxidase. The obtained results indicate the changes in the activity of antioxidant enzymes at optimal growth growth concentrations and their promising application for stimulating plant growth during phytorecultivation treatment of the waste heaps.
