Salicylic acid (SA) and methyl jasmonate(MJ) are abiotic elicitors which can increase production of secondary metabolites in plants. Effects of SA and MJ on fresh weight, flavonoids, total phenol and pigments of Madagascar periwinkle callus were investigated in two factorial experiments, in a completely randomized design. The first factor was the concentration of a different abiotic elicitor, SA or MJ in 4 levels of 0, 50, 100 and 200 μM, and the second factor was time of using different concentrations of elicitors at 2 levels of 5 and 10 days, with three replications. Based on results, the interaction between time and SA in all traits, unless fresh weigh of callus and production of anthocyanin, was significant and the interaction between time and MJ on total phenol, chlorophyll and carotenoids production was significant (P<0.01). The highest total phenol content (55.123 mg/g F.W.) was obtained from 100 μM MJ treatment for 5 days and the highest amount of flavonoid (21.467 mg/g F.W.) was obtained in 50 μM SA treatment for 5 days. Therefore, 50 and 100 μM concentrations of SA and MJ abiotic elicitors in 5 days can be used for increase the production of flavonoid and total phenol in catharanthus roseus L. callus.
