Abstract
Use of plant growth regulators has recently attracted considerable attention as an important approach to inducing natural resistance in crops. In this study, the effect of foliar application of methyl jasmonate (0, 1, 10, and 100 μM) with three replications was investigated on selected quantitative and qualitative characteristics of Physalis peruviana fruit. The evaluated parameters included fruit length and diameter, fresh and dry weight, firmness, fruit juice pH, total soluble solids (TSS), titratable acidity (TA), fruit flavor, and total phenolic and flavonoid contents. The results showed that foliar application of methyl jasmonate significantly affected the measured traits. The highest total phenolic and flavonoid contents were observed in the 100 μM treatment, while lower concentrations had a greater effect on TSS, fruit flavor, and TA. Methyl jasmonate application also had a significant positive effect on fruit length and diameter compared to the control; however, differences among the methyl jasmonate concentrations for these parameters were not statistically significant. Overall, the findings suggest that methyl jasmonate can be utilized as a safe and effective treatment for Physalis peruviana production under greenhouse conditions, thereby enhancing phenolic compound accumulation and improving both quantitative and qualitative fruit attributes.
