BIOCHEMICAL ASSESSMENT OF OXIDATIVE STRESS MARKERS IN PLANT CELLS UNDER DROUGHT CONDITIONS

Drought stress is one of the major environmental factors limiting plant growth and productivity. It induces oxidative damage through excessive accumulation of reactive oxygen species in plant tissues. This study analyzes biochemical markers of oxidative stress in plant cells under drought conditions and evaluates the adaptive role of antioxidant enzymes. The findings indicate that drought increases lipid peroxidation and alters the activity of superoxide dismutase, catalase, and peroxidase. Assessment of these markers is important for identifying stress tolerance and improving crop adaptation strategies.
