The effect abiotic elicitors on morphological and antioxidant traits of Artichoke ( Cynara scolymus )

In order to study of effect of foliar application salicylic acid on some morphophytochemicals and antioxidant of artichoke under Salt Stress, a factorial experiment in a completely randomized design with three replications at seedling stage was conducted at Greenhouse Research farm of the University of Zabol. Experimental treatments included salinity stress in 3 levels (0 , 6 , and 12 m M) and salicylic acid at 3 levels (0 , 200 , and 400 m M) . The results showed maximum numbers and length of leaves, plant height, fresh and dry weight of plant, fresh and dry weight of root were afforded by using 400 m M salicylic acid. The highest amount of total phenolic content, flavonoids, atioxidant capacity and carbohydrates were related to 400 mM salicylic acid and 12 m M salinity (0.47, 0.56, 31.24 and 5.65 respectively). On the other hand the highest of prolin (0.51) was observed in 200 m M salicylic acid and 12 m M salinity. In general could said that stress causes damaging effects of on plants and the use of salicylic acid increases the plant tolerance to salt stress.
