“…25 Accordingly, postharvest MeJA treatment delayed the ripening process of eggplant which was attributed to the increased activity of POD and CAT antioxidant enzymes and the expression of their codifying genes. 23 On the other hand, postharvest MeJA treatment increased SOD, CAT and APX activities during storage in peach and loquat fruits with respect to controls, and this effect was related to an enhanced wileyonlinelibrary.com/jsfa tolerance to CI damage. 20,21 Moreover, the increased activity of antioxidant enzymes induced by preharvest MeJA treatment in raspberry was related to an increase of the fruit resistance to decay.…”

“…On the other hand, postharvest MeJA treatment has been also effective with respect to increasing activity of antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD) and ascorbate peroxidase (APX), in loquat, peach, raspberry, eggplants and tomato, as well as pre‐harvest treatments in plum . These antioxidant enzymes are involved in scavenging the reactive oxygen species that are responsible for oxidative stress, which results in the alteration of membrane integrity and oxidation of membrane lipids and has also been associated with fruit ripening, chilling injury and pathogen attack .…”

BACKGROUND Jasmonic acid (JA) and its volatile derivative methyl jasmonate (MeJA) are hormones involved in the regulation of many processes in plants and act (when applied as a post‐ or pre‐harvest treatment) to increase fruit bioactive compounds with antioxidant potential. However, there is no literature available regarding the effect of pre‐harvest MeJA treatment on lemon fruit antioxidant systems, which was the aim of the present study. RESULTS MeJA treatment (0.1, 0.5 and 1.0 mmol L–1) increased antioxidant compounds, such as phenolics, in the juice and flavedo of ‘Fino’ and ‘Verna’ lemons at harvest, with the most effective concentration being 0.1 mmol L–1 in both cultivars. In addition, catalase (CAT), peroxidase (POD) and ascorbate peroxidase (APX) activities were also increased by MeJA treatment, with the highest increases being also found with 0.1 mmol L–1. The increases in APX and CAT were maintained from one treatment to another during fruit development on the tree, whereas the increase on POD disappeared after 8–10 days of each treatment. For both antioxidant systems, the highest increases were found in lemon harvested at the commercial ripening stage. By contrast, crop yield, fruit ripening process and quality parameters were generally not affected by MeJA treatment. CONCLUSION Preharvest MeJA treatment could be a useful tool for increasing antioxidant potential and the health beneficial effects of lemon fruit consumption, given the relationship between these properties and phenolic content. Moreover, the increased concentration of phenolics and the activity of antioxidant enzymes in the flavedo of MeJA treated fruit could increase lemon tolerance to chilling injury and decay during postharvest storage. © 2019 Society of Chemical Industry

Coriander is vulnerable to a loss in quality during storage. To improve postharvest quality, 0.68 mg/L ozone (O3) was used to treat coriander prior to storage at 20 ± 1°C. Results indicated that O3 maintained the physical appearance of the harvested coriander and suppressed both the respiration rate and polyphenol oxidase activity. O3 treatment inhibited the decline in chlorophyll content and inhibited the activity of the chlorophyll‐degrading enzymes: chlorophyllase, chlorophyll‐degrading peroxidase, Mg‐dechelatase, and pheophytinase. Results also indicated that O3 effectively inhibited the accumulation of hydrogen peroxide and the generation of superoxide anion while increasing the enzyme activity of peroxidase, catalase, and ascorbate peroxidase, compared to untreated coriander. Thus, treatment of coriander with ozone may be a useful approach for maintaining the quality and extending the shelf life of coriander through its regulation of antioxidant and chlorophyll‐degrading enzyme activity. Practical applications Coriander is prone to postharvest yellowing or wilting of its leaves when stored at ambient temperature, and its quality deteriorates due to a rapid increase in senescence. Ozone treatments have been reported to induce disease resistance, stimulate the response to oxidative stress in plants, and effectively delay the decay of fruits and vegetables. Coriander treated with ozone may be a useful approach for maintaining postharvest quality through its regulation of antioxidant and chlorophyll‐degrading enzyme activity. The study demonstrated that ozone is a potential method for suppressing the postharvest quality deterioration in horticultural corps.

“…For some nonaromatic fruit like eggplant, the role of MeJA is reversed to compare with grape, which delays postharvest ripening and senescence in the eggplant by decreasing enzymes association with phenolics metabolism [24]. The effect of MeJA on fruit ripening, TA and TSS contents is depend on the fruit species and concentration of MeJA applied [24,25].…”

Grapevine is one of the most valued and widely cultivated fruit crop worldwide, with their pleasant flavor and valuable health effects. During the consequent ripening at ambient temperature, the volatile compounds of table grape often decreased, to affect their sensory evaluation. The development of new and effective methods to increase the volatile compounds of berries is necessary. Present study was carried out to investigate the pre-harvest methyl jasmonate (MeJA) treatment on the selected volatile compounds and endogenous hormones content from 'Shine Muscat' berries pulp. The results indicated that, pre-harvest application of MeJA (0.1 mM or 0.01 mM) on grape berries generally enhanced the production of terpenes, like nerol, linalool, alpha-terpineol; While some C6 compounds were reduced, such as (E)-2-hexenol, hexanol, (Z)-3-hexenol, hexanal and (E)-2-hexenal. The endogenous hormones like IAA (indole acetic acid), ABA (abscisic acid) and JA (jasmonate acid) content were also changed after MeJA treatment. We also observed that MeJA palys a key role in fruit endogenous hormones level and volatile compounds by increasing the expression level of several related genes, such as aroma-related genes Vvter, Vv-syn and hormone-related genes VvOPR3, VvAuI, VvEth, VvNCED1. We hypothesize that, MeJA as an effective elicitor affects the volatile compounds by altering endogenous hormones level in berries pulp of 'Shine Muscat'.
