Today, many studies have been done on the effects of growth regulators on the growth and production of various crop and orchard plants, the results of which indicate that most of these hormones affect the quantitative and qualitative growth of plants. For this purpose, the effect of Jasmonic acid hormones on three different concentrations of zero (control), 10 and 50 ?m was investigated by leaf spraying method on functional and morphological traits of cucumber cultivars AROMA. The results showed that the use of jasmonic acid hormones has been effective in increasing yield and cucumber traits. The results also showed that jasmonic acid significantly increased all morphological traits, except for the number of days to flowering and the period of examination, which showed a higher mean and hormone use reduced the length of the period of examination. Comparison of the effects of hormone concentrations showed that in addition to the number of branching traits with 10 ?m concentration increasing this trait, 50 ?m concentration was more effective in other traits. In general, it can be said that the use of jasmonic acid hormone increases the yield of cucumbers and, accordingly, it can be a good and alternative approach to the production of organic products that, without using pesticides and chemical pesticides, increases the resistance of plants to tensions That produces more economic and performance.
