“…The dose of 5 mmol L ‐1 was the most effective on increasing the ascorbic acid content which led to 33 and 58% higher concentrations at harvest and after 60 days of storage, respectively, with respect to control fruits. Ascorbic acid was also significantly increased by postharvest MeJA treatments on mango fruit which was attributed to the enhanced transcription of the genes involved in the de novo biosynthesis of ascorbic acid previously reported in plant cell suspension …”

BACKGROUND: Previous reports have addressed the effectiveness of postharvest methyl jasmonate (MeJA) treatments on maintaining quality properties of pomegranate fruit during storage. However, there is no literature regarding the effects of preharvest MeJA treatments on pomegranate 'Mollar de Elche' crop yield, fruit ripening, quality attributes and bioactive compounds content (at harvest or after long-term storage), which were evaluated in this research. RESULTS: PreharvestMeJA treatments (1, 5, and 10 mmol L -1 ) increased pomegranate crop yield. MeJA at 1 and 5 mmol L -1 accelerated the on-tree ripening process, while it was delayed with 10 mmol L -1 . Losses in fruit weight, firmness and organic acids during storage at 10 ∘ C were delayed in MeJA treated fruit, leading to quality maintenance. In addition, MeJA treatments improved arils colour due to increased concentration of total and individual anthocyanins, at harvest and during storage. Total phenolic and ascorbic acid contents and total antioxidant activity [hydrophilic (H-TAA) and lipophilic (L-TAA) fractions] were also higher in arils from treated pomegranate fruits than in controls. CONCLUSION: Preharvest treatments with MeJA could be a promising tool to improve pomegranate crop yield, fruit quality and its content in bioactive compounds at harvest and during storage. The higher effects were obtained with MeJA at 5 mmol L -1 dose, which could be the selected treatment for practical application purposes.

“…The results obtained regarding AsA increases, in lemon pulp and peel, in the presence of EO vapor, are in line with recent studies on treatment with compounds such as methyl jasmonate, nitric oxide, salicylic acid, and essential oil that have proven to elicit and stimulate the inductive-defensive system and extend the shelf life of fruits and vegetables [43][44][45].…”

Assessment of Mint, Basil, and Lavender Essential Oil Vapor-Phase in Antifungal Protection and Lemon Fruit Quality

et al. 2020

There is an increasing interest in developing natural methods to replace the current chemicals used for maintaining postharvest quality of citrus fruits. The essential oil antifungal activity of mint (MEO), basil (BEO), and lavender (LEO) acting as the vapor-phases was tested against Penicillium digitatum. The minimum doses with fungistatic and fungicidal effect, in vitro, acting as the vapor-phases, were set up. The minimum fungicidal dose was 300 μL for BEO and 350 μL LEO, while for MEO only minimal dose with fungistatic effect was reached. The IC50 values were calculated and used (v/v) for testing preservation of lemon fruits, in close space enriched in vapor oil. For this purpose, the following two independent in vivo experiments were carried out: experiment 1, inoculated lemons with P. digitatum stored without chemical treatments 7 days, at 22 ± 2 °C, at two concentrations (C1—IC50 equivalent; C2—half of C1); and experiment 2, the non-inoculated lemons kept under the same conditions and concentrations of EO vapor served to evaluate the lemon quality properties. The results showed that antifungal protective effect was provided in the order of LEO-C1 > BEO-C1 > MEO-C1 > BEO-C2 > MEO-C2 > LEO-C2. The quality indicators like weight loss, pH, and firmness were not negatively influenced.

“…8 shows a working model of natural pepper fruit ripening during the transition from green to red, in which multiple parameters of nitro-oxidative metabolism are modulated. Finally, in addition to the relevance of NO as a regulator of pepper fruit ripening, which is independent of ethylene, the potential involvement of other endogenous molecules, such as H 2 O 2 , ABA, H 2 S, or melatonin, which could exert synergistic or antagonistic actions to NO, establishing a complex network of signals, as has been reported elsewhere (Corpas et al, 2019; Mukherjee 2019; Vithana et al , 2019), should be mentioned. The mechanisms that govern these interactions, and how they modulate the whole ripening process, should be deciphered in future research.…”

Ripening is a complex physiological process that involves changes in reactive nitrogen and oxygen species that govern the shelf-life and quality of fruits. Nitric oxide (NO)-dependent changes in the sweet pepper fruit transcriptome were determined by treating fruits at the initial breaking point stage with NO gas. Fruits were also harvested at the immature (green) and ripe (red) stages. Fruit ripening in the absence of NO resulted in changes in the abundance of 8805 transcripts whose function could be identified. Among these, functional clusters associated with reactive oxygen/nitrogen species and lipid metabolism were significantly modified. NO treatment resulted in the differential expression of 498 genes framed within these functional categories. Biochemical analysis revealed that NO treatment resulted in changes in fatty acid profiling, glutathione and proline contents, and the extent of lipid peroxidation, as well as increases in the activity of ascorbate peroxidase and lipoxygenase. These data provide supporting evidence for the crucial role of NO in the ripening of pepper fruit.
