Background and Objectives: Salinity stress is one of the major challenges to the sustainability of natural ecosystems, significantly affecting plant growth and performance, especially in arid and semi-arid regions. The physiological traits of Lycium depressum make it an ideal candidate for desertification control and soil salinity reduction due to its relative resistance to harsh environmental conditions. Recently, it has been targeted in restoration programs for saline and alkaline rangelands. This study aimed to investigate some morphological and phytochemical characteristics of L. depressum Stocks. inoculated with mycorrhizal fungi under salinity stress conditions.
Materials and Methods: To assess the impact of mycorrhizal fungi on changes in some morphological and phytochemical characteristics of L. depressum under salinity stress, a factorial greenhouse experiment was conducted in a completely randomized block design with four replications. The experimental factors included: 1) Arbuscular Mycorrhizal Fungi Funneliformis mosseae (F1), Rhizophagus intraradices (F2), and their combination (F1+F2), along with a control group (without fungi F0); 2) Four levels of salinity stress (S1=6, S2=10, S3=14, and S4=18 dS/m).
Findings: The results indicated that both the simple and interaction effects of salinity treatments and fungi on the studied traits were significant (P < 0.05). The highest levels of phenols, flavonoids, antioxidants, and proline occurred in the treatment with the highest salinity level (S4) and the combination of the two fungal species F1+F2, whereas the lowest levels were observed in the control group (without fungi) and the lowest salinity level (S1). Conversely, the highest greenness, fresh leaf weight, dry leaf weight, leaf count, and plant height were recorded in the treatment with the fungal combination F1+F2 at the lowest salinity level (S1), while the least values for the measured morphological parameters were found in the control treatment without fungi (F0) at the highest salinity level (S4).
Conclusion: Based on the findings, it was observed that salinity stress negatively impacts the morphological characteristics of L. depressum, but inoculation with mycorrhizal fungi significantly mitigates these negative effects. Overall, it can be concluded that the use of mycorrhizal fungi, especially the combination of species F1+F2, can effectively enhance plant tolerance to salinity stress and improve their phytochemical and morphological traits. These findings emphasize that leveraging these fungi as an effective strategy can play a crucial role in the restoration and rehabilitation of degraded rangelands affected by environmental stresses, particularly salinity, thereby aiding in the restoration of ecosystem health and productivity.
