Abstract
Due to Iran�s location in saline areas, salinity is one of the fundamental problems in the cultivation of plants such as mint. Jasmonic acid causes growth enhancement and efficiency of a plant in different environmental stresses. Therefore, in this study, the effect of jasmonic acid on some phytochemical and morphological traits of Mentha piperita L. was studied in saline condition. In this study, a factorial experiment in a completely randomized design and methyl jasmonate in 0 level (control treatment), 50, 100 & 150 mM and 0 salinity (without adding salt) as well as 1.5, 3 & 4.5 dS/m individually and in combinations with each other were applied with 16 treatments and 3 replications. The results showed that the factors used had significant effects on the catalase, peroxidase and superoxide dismutase activity. Maximum proline was observed in salinity of 5-4 dS/m and 0 mM concentrations of jasmonic acid. These results showed that the application of jasmonic acid led to increase in growth factors such as height, fresh and dry weight, number of flowers and tributaries and hence, it could be involved in increased resistance to salt stress.
