Abstract:
This experiment was carried out to investigate the effect of methyl jasmonate and salicylic acid on the antioxidant production and physiological-biochemical properties of Chelidonium majus under drought stress condition. For this, an experiment was conducted as factorial based on completely randomized design with four replications in Imam Khomeini International University during 2016-2017. Three factors included drought stress in two levels (non-stress and drought stress with 100% and 50% field capacity irrigation, respectively), elicitor in three levels (control, 100 μm methyl-jasmonate and 2 mM salicylic acid) and plant organs (root, stem and leaf). Analysis of variance and mean comparisons showed that methyl-jasmonate and salicylic acid reduced the activity of CAT enzyme. Both salicylic acid and methyl-jasmonate did not affect the activity of SOD, but methyl-jasmonate increased the activity of GPX and salicylic acid reduced APX activity under drought stress. Also, methyl-jasmonate and salicylic acid reduced APX activity compared to control treatment. The highest amount of protein content was observed in root and then in leaf. Salicylic acid increased total protein content up to 34% compared to control treatment. Both Methyl-jasmonate and salicylic acid increased chlorophyll chlorophyll, carotenoids, flavonoids and anthocyanin compared to control treatment, but salicylic acid was superior in increasing of chlorophyll and carotenoids whereas methyl-jasmonate was superior in increasing of flavonoids and anthocyanin. In conclusion, methyl-jasmonate and salicylic acid have increased the ability of celandine in response to drought stress, and also, in addition to the protective effect against drought-induced oxidation, they increased photosynthetic pigments and some of metabolites.
