Abstract Salinity is a significant abiotic stress that adversely affects plant growth and

development, threatening global agricultural productivity, particularly in arid and semi-arid

regions. Results indicated that increasing salt concentrations significantly inhibited seedling

growth in all studied parameters, with control plants (0 mM) exhibiting the highest growth

values. The tallest plants measured 23.16 cm in the control treatment, while those exposed to

200 mM salt reached only 13.12 cm. Although AMF applications did not show significant

effects on plant height, they positively influenced growth parameters in salt-free conditions.

Statistical analysis revealed significant interactions between salt levels and AMF on root fresh

and dry weights, with the highest values recorded in the control group. Furthermore, AMF

applications generally promoted growth, particularly in non-saline conditions, corroborating

findings from previous research highlighting mycorrhizae's role in enhancing plant stress

tolerance. In conclusion, the research findings emphasize the detrimental impact of salinity on

plant development and the potential of mycorrhizal inoculation as a strategy to mitigate these

effects. These findings contribute to understanding the beneficial role of AMF in improving salt

tolerance and promoting sustainable agricultural practices in saline-prone environments.
