Salinity is one of the environmental stresses that has a negative effect on the growth process and its causes oxidative stress in plants. A factorial experiment was carried out in the form of a completely randomized design, in order to investigate the effect of SNP on reducing the oxidative stress of Salicornia Persica, under salt stress, with three repetitions. In this research, the effect of two levels of SNP (0 and 0.2 mM), three levels of salinity (0, 200, 500 microgram/ml sodium chloride) and three stages of harvest (1, 7 and 14 days) were evaluated. The results showed that the dry weight of aerial parts decreased with increasing salinity. The exception was an increase in salinity of 200. The positive effect of SNP was observed in salinity of 200 and 500. The content of relative water decreased with increasing salinity concentration and SNP caused the content of relative water increased at three levels of salinity. The amount of anthocyanin decreased with increasing salinity and SNP caused an increase in the amount of anthocyanin. Malondialdehyde increased with increasing salinity, and the application of SNP caused its decrease. The amount of phenol decreased with increasing salinity and SNP did not have a significant effect on phenol. However, the amount of flavonoids increased at 200 salinity compared to control and it’s decreased at 500 salinity. Salinity stress caused an increase in the amount of sodium and the application of SNP caused it’s to decrease. The amount of potassium increased at 200 and 500 salinity. The treatment of SNP caused an increase in the amount of potassium at 0 and 500 salinity. In general, it can be concluded that the treatment of SNP can increase Salicornia Persica Salinity tolerance.
