Abstract :
In order to investigate The effect of salicylic and jasmonic acid on antioxidant enzymesactivity, soluble carbohydrate and proline in artichoke (Cynara Scolymus L.) under salt stress conditions, a research was conducted in 2014 at Islamic Azad University, Yadgar-e-Imam (RAH) Shahre Rey Branch. The experiment was done as factorial based on completely random design with four replications, the first factor salinity stress in four levels 0, 25, 60, and 95 mM, the second factor in two levels no consumption and consumption of 0.7 mM salicylic acid and the third factor no consumption and consumption of 100 µm jasmonic acid were considered. The results showed that all three main effects of salinity stress, salicylic acid and jasmonic acid consumption on antioxidant enzymes activity, soluble carbohydrate and proline content were significant at the 1% probability level, so in salinity stress conditions, the enzyme activity showed a significant increase and the highest level of activity was gained in 95 mM sodium chloride and the lowest one was related to the non applying of salt stress. Also, under the conditions of salicylic acid and jasmonic acid foliar application, the activity level of antioxidant enzymes and soluble carbohydrate and proline content increased and as the result the resistance of artichoke resistance to salt stress improved.
