Abstract: Triticum aestivum L. (common wheat) is one of the most widely cultivated cereal crops globally and represents a staple food source in many regions. Its grains are essential for producing a variety of food products and play a critical role in the human diet by supplying carbohydrates, proteins, vitamins, and various bioactive compounds. In the Mediterranean basin, Triticum aestivum is predominantly cultivated under rain-fed conditions, making it highly susceptible to abiotic stresses such as drought and salinity. These stressors can significantly impact yield potential and alter the grain?s qualitative attributes. Abiotic stress at the cellular level triggers the production and accumulation of reactive oxygen species (ROS), leading to oxidative stress. This condition can compromise cellular integrity and functionality. In the present study, we investigated the oxidative response of Triticum aestivum during germination and early growth stages under different abiotic stress conditions. Specifically, we analyzed the regulation of malondialdehyde (MDA), proline, hydrogen peroxide, soluble protein, and catalase activity in response to water and salt stress, as well as exposure to artificial light in controlled laboratory conditions. Our results demonstrated a significant increase in the total specific activity of antioxidant and stress-related markers after 7 days of stress treatment. Notably, water and salt stress led to pronounced changes in oxidative stress indicators. These findings suggest that Triticum aestivum employs a broad range of physiological and biochemical mechanisms to mitigate the impact of abiotic stress, potentially including morphological adaptations. Future investigations will focus on further biochemical profiling, including enzyme activity assays and native gel electrophoresis, to better understand the molecular mechanisms underlying stress tolerance in Triticum aestivum.
