In recent decades, Ukraine has been experiencing abnormally high temperatures and droughts in different seasons, including autumn. This creates stressful conditions for winter cereals, especially wheat, at the very beginning of ontogeny. A comprehensive study of the functioning of antioxidant and osmoprotective systems in the early stages of development for wheat varieties of different ecological and geographical origins has not been conducted yet. This study aimed to investigate the effect of heat stress on the growth of etiolated seedlings of seven varieties of winter wheat (Triticum aestivum L.) and the indicators characterizing the functioning of antioxidant and osmoprotective systems.
