چکیده

Halophyte plants growing in slain environments, in some cases they have economic applications in addition to those potential to saline soil improvement. Aeluropus littoralis is one of the forage halophyte plants growing around the Omiya Lake. In this study, the effect of different NaCl levels (۰ to ۵۰۰ mM) on plant growth and biochemical composition including total soluble protein, phenolic compounds, flavonoids, sugars and phosphorus contents. The main aim of this study was determination of salinity level in which the plant shows higher economic value. It is higher to be determined. The results showed that the growth and protein content of shoots and roots of this plant decreased until to ۳۰۰ mM of NaCl and then increased slightly. In contrast to insoluble sugar, the soluble sugar content increased and the highest amount was obtained in ۳۰۰ mM of NaCl. Contrary to phosphorus concentrations, phosphorus content decreased. According to results it can be concluded that this plant has high sugar content and if the goal of plant cultivation is to achieve sugar, that cultivation at the level of ۳۰۰ ml of sodium chloride is recommended. At higher salinity levels, this plant slightly increased phosphorus uptake. Therefore, mechanisms involved in phosphorus uptake will be investigated. In addition, antioxidant compounds including phenolic and flavonoid compounds increased in presence of salt, Therefore, the investigation of therapeutic value of these compounds and the possibility of this plant cultivation in the presence of ۴۰۰ mM sodium chloride, which led to highest phenolic and flavonoid compounds, will be interesting.
