DOI:https://doi.org/10.53040/ppap2023.44.In recent years, due to the climate changes, the growth and development of corn is affected by heat stress, especially at an early stage of ontogeny. Influence of biostimulant Reglalg, used for seed pretreatment of maize hybrids Por. 310 and Por. 374 before exposure to heat shock (HS) at 50°C for 30 min, on catalase (CAT), peroxidase (PO), and lipid peroxidation (LPO) of root seedlings was studied. Compared to the Reglalg variants, root growth of control seedlings was more strongly affected by HS, since the activity levels of CAT, PO and MDA content in the roots were higher. This demonstrates the beneficial effects of Reglalg in increasing maize tolerance to HS.roCatalazeperoxidaselipid peroxidationmaize rootsheat shockReglalgArticle
