Background and objectives: Salinity stress is a major environmental challenge affecting plant growth and performance, particularly in arid and semi-arid regions. The physiological characteristics of Lycium depressum make it a promising candidate for desertification control and soil salinity reduction due to its resilience to harsh conditions. Given its recent inclusion in restoration programs for saline and alkaline rangelands, this study investigates the morphological and phytochemical traits of L. depressum inoculated with mycorrhizal fungi under salinity stress.
Methodology: A factorial greenhouse experiment was conducted using a completely randomized block design with four replications to assess the effects of mycorrhizal fungi on L. depressum under salinity stress. The experimental factors included: Arbuscular Mycorrhizal Fungi – Funneliformis mosseae (F1), Rhizophagus intraradices (F2), their combination (F1+F2), and a control group (without fungi, F0). Salinity Stress Levels – Four treatments (S1=6, S2=10, S3=14, and S4=18 dS/m).
Results: The results demonstrated significant effects (P < 0.05) of both salinity treatments and fungal inoculation on the studied traits. The highest levels of phenols, flavonoids, antioxidants, and proline were recorded in the highest salinity treatment (S4) with the fungal combination (F1+F2), while the lowest levels were observed in the control group (F0) at the lowest salinity level (S1). Conversely, leaf greenness, fresh leaf weight, dry leaf weight, leaf count, and plant height reached their highest values in the fungal combination (F1+F2) at the lowest salinity level (S1), whereas the lowest values were observed in the control treatment (F0) under the highest salinity level (S4).
Conclusion: Salinity stress adversely affects the morphological traits of L. depressum, but mycorrhizal fungi inoculation significantly mitigates these negative impacts. The combined fungal treatment (F1+F2) demonstrated the most substantial benefits, improving plant tolerance to salinity and enhancing phytochemical and morphological traits. These findings highlight the potential of mycorrhizal fungi as an effective strategy for rehabilitating degraded rangelands affected by environmental stresses, particularly salinity, thereby contributing to ecosystem health and productivity restoration.
