Effect of foliar application with methyl jasmonate on some physiological, phytochemical and antioxidant activity of Physalis peruviana L.

Physalis is one of the most important tropical fruits that has attracted worldwide attention due to its bioactive compounds, potential for intensive cultivation and good storage life. In recent years, the use of plant growth regulators to stimulate plant natural resistance has increased remarkably. In order to study the effect of foliar application with methyl jasmonate on some physiological, phytochemical and antioxidant activity of Physalis peruviana L., a pot experiment was conducted in a completely randomized design with three replications (two pots for each replication) in the research greenhouse of the Department of Horticulture, Urmia university. Different concentrations of methyl jasmonate (۰, ۱, ۱۰ and ۱۰۰ μM) were used in this study. The results showed that foliar application with methyl jasmonate had a significant effect on most of the evaluated traits. According to the results, content of leaf fresh and dry weight, total phenol, flavonoids, antioxidant activity, photosynthetic pigments of chlorophyll a and b, carotenoid, beta-carotene significantly increased compared to the control
