Abstract :
Soil salinity is one of the factors that can put farmers at risk, so special arrangements should be made in this regard. Identifying some physiological mechanisms in strawberry plants is essential in the face of salinity. Methyl jasmonate is a plant growth regulator that affects many biochemical and physiological processes of the plant. . The experiment was a factorial based on randomized complete block design with three replications in 3 treatments and 378 plants with different concentrations of methyl jasmonate (0, 1, 2 μm) under salinity stress conditions with levels of 0, 5 and 10 Decimens) on some morphological responses (plant height, leaf area, dry weight and plant weight) and physiological (soluble solids, vitamin C and acidity) and yield (number of fruits, fruit weight and fruit yield) in the year 2018-2019 in the city of Azad Shahr, Golestan province, in two cultivars of Fragaria × Ananassa Duch., Queen Eliza and Parus strawberries. The results of this study showed that salinity stress significantly reduced the morphological and physiological properties of two strawberry cultivars Queen Eliza and Parus. Quantitative properties of plant height, leaf area, dry weight of plant, and qualitative properties of soluble material, vitamin C and acidity decreased with increasing salinity and with the effect of methyl jasmonate significantly increased vegetative and reproductive growth.
