Özet
One of the major abiotic stresses limiting agricultural productivity globally is salinity. Seed priming is a successful approach to improve stress tolerance, particularly during the early stages of plant growth. This study investigates the effects of ascorbic acid (AsA) based seed priming on the physiological and molecular responses of salt-stressed maize. Under controlled conditions, maize seeds were primed with AsA and exposed to different concentrations of NaCl. Physiological parameters such as ion leakage, turgor loss, and total chlorophyll content were evaluated, along with biochemical and protein-level analyses. The results showed that AsA priming improved plant water status, reduced ion leakage, and helped maintain chlorophyll content under salinity stress. In addition, primed plants exhibited higher proline accumulation and increased total protein content, indicating improved stress adaptation. SDS-PAGE and immunoblot analyses confirmed that dehydrin proteins were strongly induced under salt stress and further enhanced by priming treatments. These findings demonstrate that AsA-based seed priming enhances salt stress tolerance in maize through coordinated physiological and molecular mechanisms. Overall, this study highlights the potential of seed priming as a valuable tool for sustainable agriculture and provides insights into the role of stress-related proteins in priming-induced stress responses.
