Salicylic Acid is a plant growth regulator involved in regulating physiological processes and plant response to adverse biological conditions such as salinity. Meanwhile, salinity is a major constraint for food production. Due to the detoxification of superoxide radicals produced as a result of salinity, salicylic acid plays an important role in preventing oxidative damages to plants. In the present research the effect of salicylic acid different concentrations, salinity and interaction effects of salicylic acid and salinity on morphological and biochemical parameters in barley was studied. Salinity concentration of zero, 25, 50, 75 and 100 milliMoar and salicylic acid concentration of zero, 0.5, 1 and 1.5 milliMolar were used in a completly randomized design as factorial in 2015.The results of this research showed that salinity reduced shoot and root growth, fresh weight and dry weight of shoots and roots, as well as reduction of chlorophyll and carotenoid; while in salicylic acid pre-treated plants, the amount of this reduction has been adjusted.On the other hand, increasing the amount of anthocyanins, chlorophylls and carotenoids indicates the role of consumption of one and one milliMolar salicylic acid in increasing the tolerance of this plant to salt tension. By examining the above, it can be concluded that the application of salicylic acid increases the tolerance of the plant to counteract the tension of salinity. |
