Abstract :
Soil salinity is one of the main stresses of plants Acid salicylic acid plays a role in the regulation of various physiological processes and plant growth. A pilot study was conducted to investigate the use of salicylic acid on some of the traits of strawberry in salinity and factorial based on randomized complete block design with two treatments in 3 replications and 189 plants with different concentrations of salicylic acid (0 , 2 and 4 mM) under conditions of salinity stress (0, 5 and 10 dS) on some morphological characteristics (plant height, number and leaf area, fresh and dry weight of the plant) And physiological (soluble solids and acidity) and yield (number of flowers per plant, number of fruits, fruit weight and fruit yield) in Azad Shahr city of Golestan province in 2019-2018 in two cultivars of Fragaria × ananassa Duch, Queen Eliza and Paros. The results of this study showed that salinity stress significantly decreases vegetative and reproductive growth of the plant by increasing its concentration and its effect is more. And the use of salicylic acid significantly increased the growth of these traits. Among the fungicidal concentrations of salicylic acid, the highest amount of flower number, number of fruits, fruit weight and yield was observed in 2 mg / L acid salicylic acid treatment. In interaction of these two treatments, the highest level of fruit quality was observed in treatment (salinity of 5 dS / m × 4 mM acid salicylic acid) in both cultivars.
