Salinity stress severely impacts wheat productivity, necessitating effective strategies to enhance crop resilience. This study investigates the potential of Penicillium chrysogenum CM022 as a biological agent alleviate impact salinity on (Triticum aestivum L.). P. improved germination seeds, particularly under 150 mM NaCl. Fungal inoculation significantly plant growth in terms root length, height, and seedling biomass, even high conditions. Notably, inoculated plants preserved photosynthetic pigments reduced oxidative damage, evidenced by lower levels hydrogen peroxide (H₂O₂) malondialdehyde (MDA), compared non-inoculated controls. The also exhibited enhanced proline soluble sugar contents, which are crucial for osmotic adjustment stress. Additionally, increased antioxidant capacity wheat, boosting total phenolic flavonoid enhancing enzyme activity salinity. These findings underscore improving tolerance through physiological, biochemical, defense mechanisms, supporting its use sustainable agricultural practices mitigate adverse effects production.
