Changes of Oxidative Status of Triticum aestivum L. during Germination and Initial Phase of Growth Subjected to Abiotic Stress
Abstract: Triticum aestivum is one of the most commonly cultivated species in the world and represents a key commodity for many areas worldwide, as its grain is used in the production of various foods and has a relevant role in the human diet, providing carbohydrates, proteins, vitamins, etc. as well as highly valued bioactive compounds. It is largely cultivated in the Mediterranean basin, where it is mainly grown under rain - fed conditions, thus currently undergoing abiotic stress, which can hamper yield potential and influence the qualitative characteristics of grain. When plants suffer abiotic stress, damage is established at the cellular level. This leads to the accumulation of ROS thus generating in turn an oxidative stress condition, which can ultimately result in the impairment of cellular integrity and functionality. This study investigates oxidative stress responses in Triticum aestivum L. during germination and early growth when subjected to abiotic stresses, including drought and salinity. Key biochemical markers such as malondialdehyde (MDA), proline, peroxide, soluble protein, and catalase activity were measured. Results indicated significant increases in oxidative stress indicators under both water and salt stress, suggesting severe impairment of cellular function. The findings highlight the plant's adaptive mechanisms and call for further exploration into enzyme behaviour under stress to improve wheat resilience.
