Elicitation is a valuable tool to improve essential oil production. In order to evaluate the effects of methyl jasmonate (MJ) and salicylic acid (SA) as elicitors in the morphophysiological attributes and in the content and profile of essential oil (EO) of lemon balm (Lippia alba). In a greenhouse, L. alba plants were cultivated and subjected to foliar spraying with solutions of Methyl Jasmonate (0, 1, 2 and 4 mM) and Salicylic acid (0, 1, 2 and 4 mM). The results indicated that the concentrations used did not increase plant growth, however, it stimulated the increase in the number of inflorescences per plant. The EO contents were favored with the elicitation, with productivity varying between 0.57 and 0.89%, higher than the control treatment with distilled water (0.45%). Application of MJ and SA affected chloroplast pigments, gas exchange parameters and trichomes density. Chemical analysis of essential oils identified the presence of 78 compounds. The MJ induced the presence of 71 compounds, being 16 exclusive, while the plants treated with SA presented 35 compounds, having only as exclusive. The major compounds varied according to the treatments, however, the main substances were Geranial, Geraniol, β-caryophyllene, Caryophyllene oxide, Germacrene D, Myrcene and Eugenol. Therefore, the application of elicitors in L. alba plants, especially at concentrations of 2 mM of MJ and 4 mM of SA, has the potential to modulate physiological responses and stimulate secondary metabolism, as well as the production of certain molecules, such as monoterpenes, sesquiterpenes and phenylpropanoids.
