Research on the influence of the Reglalg biostimulator in combination with micro elements on the activity of peroxidase and catalase in the leaves of some plum varieties

The foliar treatments applied with the biostimulator Reglalg, in combination with microelements B, Zn, Mn, Mo, contribute to increasing the activity of catalase and peroxidase in the leaves of plum trees, the lockout varieties Udlinennaia and Superprezident, the foreign selection varieties Stanley and Prezident, introduced in Moldova throughout of vegetation of the year 2023. An enzyme is a biological component that increases the rate of a chemical reaction by lowering the activation energy barrier. Catalase and peroxidase are enzymes. The activity of the peroxidase and catalase enzymes changed during the vegetation period depending on the biological characteristics of the varieties, the metabolic processes in different phenophases, the action of high temperatures and the action of the substances used to treat the trees during the vegetation period.
