Abstract
Abstract: Considering the increasing trend of salinity development and lack of desirable land for agriculture in the world, the use of saline resistant species or the use of compounds that reduce the effects of salinity stress and induction of resistance to stress in plants is very important. Salicylic acid is one of the beneficial compounds for plants, which plays an important role in the resistance of plants to environmental stresses, including salinity stress. To evaluate the potential beneficial effects of salicylic acid on some of the physiological and morphological parameters of an experiment, a factorial experiment was conducted in a completely randomized design with two factors: salinity including sodium chloride at 0, 100 and 150 mM and salicylic acid at two levels 0 and 1 mM with four repeats. At the end of experiment, vegetative traits, chlorophyll a, b, total, carotenoids, starch, sucrose and total protein content were measured after 28 days of treatment. The results of salinity and salicylic acid interaction showed that salinity significantly reduced the weight and dry weight of the shoot, root dry weight and root, root penetration depth, and the height of the forage plant. Salinity of 150 mM significantly reduced the amount of chlorophyll a and b. In addition, the amount of sucrose and starch and protein decreased by salinity. Treatments with salicylic acid increased vegetative traits, sugars, chlorophyll, carotenoids and protein under salinity stress significantly.
