چکیده فارسی مقاله
Salinity stress is one of the most important environmental stresses limiting plant growth and performance. Salicornia persica is a species of Chenopodiaceae family; it is a halophyte and resistant to salinity. In addition, salicylic acid is known as an important molecule for the adaptation of plant responses to environmental stress. In the present study, the effect of salinity and salicylic acid on some morphophysiological traits of plants treated with three sodium chloride concentrations (zero, 200, and 500 ppm) and two salicylic acid concentrations (zero and 0.1 mM) and three harvest durations (1, 7, and 14 days) was investigated. This experiment was conducted as a factorial experimental design in the form of a completely randomized experimental design with three replicates. The initial results of the petridish trials showed that during salinity stress with increase in shoot length and decrease in the malondialdehyde levels compared to the control, the 0.1 mM salicylic acid treatment was more effective than other concentrations. The potting results showed that salinity stress caused a significant decrease in shoot and root dry weight. In addition, salt stress let to an increase in the amount of flavonoids and soluble sugars in most crops. The effect of salinity stress on the amount of pigments showed no particular trend. The amount of potassium increased at a salinity of 200 ppm and decreased at 500 ppm. The use of 0.1 mM salicylic acid increased the dry weight of the roots in all harvests. In addition, the use of salicylic acid increased the amount of chlorophyll b at salinity levels of 200 and 500 ppm. Also, the application of salicylic acid let to an increase in the amount of flavonoids at a salinity of 500 ppm, while the amount decreased at a salinity of 200 ppm. The application of 0.1 mM salicylic acid increased the content of potassium and soluble sugars in most harvests at 200 and 500 salinity levels. In general, the modulating effect of 0.1 mM salicylic acid on salinity stress was observed in Salicornia persica in most cases.
