Abstract :

 In order to investigate the effect of salicylic acid and jasmonic acid foliar application onsome morphological traits of artichoke (Cynara scolymus L.) under salt stress conditions,an experiment was conducted in 2014 at Islamic Azad University, Yadgar-e-ImamKhomeini (RA) Shahre Rey Branch. The experiment was done as factorial based oncompletely randomized design with four repetitions, the experimental factors include:salinity stress in four levels: 0, 25, 60 and 95 mM, salicylic acid foliar spraying in twolevels non-use (control) and 0.7 mM consumption and spraying of jasmonic acid wasconsidered in two levels: no consumption (control) and 100 µM. The results of varianceanalysis showed that the simple effects of salinity stress, application of salicylic acid andjasmonic acid were significant on all investigated traits, and among these traits, rootlength, number of leaves and root dry weight were influenced by the triple interactioneffects of experimental factor. The simple mean comparison results indicated that undersalt stress conditions with 95 mM sodium chloride, the lowest plant height (41.93 cm),root length (9.79 cm), number of leaves (4.62) , the leaf area of a single plant (140.73),the fresh weight of aerial parts (12.93 grams), the dry weight of aerial parts (2.46 g) androot dry weight (1.42 g) were obtained. The highest amount of shoot dry weight )7.42 g(observed in non salinity stress and spraying with 100 µM jasmonic acid and themaximum amount of root dry weight )3.03 g( were gained in non salinity stress, using 0.7mM of salicylic acid and 100 μM of jasmonic acid conditions. Therefore, it can be statedthat the use of salicylic acid and jasmonic acid as anti-stress agents improved all themorphological characteristics of the artichoke medicinal plant.
