چکیده فارسی مقاله
Portulaca oleraceae L. (purslane) is one of the most nutritious leafy vegetables that contain high fatty acids and antioxidants. Salinity was the main environmental stress limiting plant growth and development. Arbuscular mycorrhizal fungi (AMF) can colonize a wide range of host plants and facilitate the absorption of soil resources. The purpose of the study was to survey the impacts of NaCl treatments (0, 40, 80, 120, and 160 mM) and symbiosis of AMF (Glomus intraradices and Glomus mosseae) on growth parameters, phytochemical compounds, and fatty acid profile on purslane. The seeds of purslane were treated with a mycorrhizal fungus and salt stress. Root colonization percentage, growth parameters, flavonoid content, phenolic compounds, antioxidant capacity, and fatty acid profile on purslane were evaluated. The results indicated that the highest colonization rate was observed in roots inoculated with G. intraradices. Salinity progressively reduced the growth, but AMF symbiosis did not have a significant effect. The highest phenolic compound and flavonoid content belonged to the plants subjected to 120 mM NaCl. The lowest DPPH (IC50) was observed in plants inoculated with G. mosseae. The phenolic compounds and flavonoid content in the leaves colonized with G. mosseae are significantly higher than in G. intraradices. Mycorrhizal symbiosis and increasing salinity negatively affected the fatty acid profile. The highest α-Linolenic content was observed with 40 mM NaCl treatment. Purslane can tolerate a moderate level of salt stress and has a high amount of antioxidants and fatty acids, which makes it possible to use it in saline localities.
