Abstract

Salt stress is a major abiotic factor that adversely affects wheat growth, leading to biochemical imbalances and reduced crop productivity. In recent years, nanotechnology has emerged as a promising approach to mitigate the detrimental effects of salinity in plants. The objective of the research is to investigate the role of silver nanoparticles (AgNPs) in modulating the biomechanical properties of wheat (Triticum aestivum) under salt-stress conditions. The effect of seed priming AgNPs at concentrations of 0, 1, 2, 5, 10, and 15 mM was followed by exposure to 175 mM NaCl to induce salt stress. Taurine, starch content, catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD) activity are used to evaluate the biochemical characteristics. Compare the growth and biochemical parameters under different conditions (control, salt stress, and AgNP treatments). Analyze the effect of various concentrations of AgNPs on wheat growth and stress-related biochemical responses. Results showed that the 175 mM NaCl salt stress significantly reduced shoot fresh and dry weights and taurine and starch content while increasing CAT, POD activities, and SOD activity. Seed priming with AgNPs improved wheat growth under normal and salt-stressed conditions, with higher concentrations (10 mM and 15 mM) showing enhanced shoot fresh and dry weight. Salt stress and combined AgNPs increase the levels of taurine and starch content while decreasing CAT activity and raising POD activity. The research highlights the potential of nanotechnology in sustainable agriculture and provides insights into the use of AgNPs for improving crop tolerance to adverse environmental conditions.
