The aim of the present study was to evaluate the potentiality of fluorescence characteristics for the determination of disease index. In this study, postharvest green peppers were inoculated with <em>Alternaria alternaria</em> and stored at ambient temperature, the lesion diameter, ergosterol content, and chlorophyll fluorescence parameters were determined. The green pepper fruit was also extracted with ethanol and water, and the traditional excitation wavelengths at 254 nm and 365 nm were used to screen optimal emission wavelength, and corresponding fluorescence intensities were determined. Ergosterol content was found to be correlated with lesion diameter. It was observed that the number of emission peaks of the multi-color fluorescence of ethanol extract from peppers were more than those of water extract. Using both excitation wavelengths at 254 nm and 365 nm yielded 3–4 types of visible fluorescence, in contrast to 1–2 types obtained with a single excitation wavelength. The ethanol extract of peppers after column chromatography with an excitation wavelength of 225 nm, one fluorescence in the ultraviolet region and four visible fluorescence including red, cyan, purple, and blue were obtained. Red and blue fluorescence might be chlorophyll fluorescence and flavonoid fluorescence, respectively, while cyan and purple fluorescence were composite colors of multiple fluorescence. The fluorescence intensity with excitation and emission matrix (EEM) 225 nm/324 nm, electron transport rate (ETR), photochemical quenching (qP) showed high correlations with lesion diameter, of which correlation coefficients were 0.99^**, −0.98^** and −0.98^**, respectively. Finally, it was suggested that the fluorescence intensity with EEM 225 nm/324 nm, ETR and qP would be potential to be probes for fungal disease index in postharvest green peppers.</div></div>","PeriodicalId":20328,"journal":{"name":"Postharvest Biology and Technology","volume":"219 ","pages":"Article 113246"},"PeriodicalIF":6.4,"publicationDate":"2024-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142419118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trehalose is a natural product with excellent biological activity and safety. In this work, the ability of trehalose to mitigate the browning of ‘Feizixiao’ litchi fruit stored at 25 °C and its physio-biochemical mechanisms were evaluated. The application of trehalose at 2.5 g L⁻¹ to litchi fruit delayed browning and redness loss. Trehalose treatment alleviated oxidative stress-induced impairment of membrane system, as indicated by reduced generation of O₂^-., H₂O₂ and malondialdehyde (MDA) and lowered relative electrolyte leakage (REL), which was a result of increased activities of antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR). Compared to control fruit, repressed activities of polyphenol oxidase (PPO) and peroxidase (POD) coincident with higher contents of total phenolics, flavonoids, anthocyanins, procyanidin B2 and cyanidin-3-O-glucoside were observed in fruit receiving trehalose, indicating an amelioration of enzymatic browning by trehalose treatment. Furthermore, trehalose treatment stimulated the expression of anthocyanin biosynthetic genes (<em>LcPAL</em>, <em>Lc4CL</em>, <em>LcCHS</em>, <em>LcCHI</em>, <em>LcANS</em>, <em>LcDFR</em> and <em>LcUFGT</em>) and their transcriptional activator genes (<em>LcMYB43435</em>, <em>LcMYB18362</em>, <em>LcMYB30086</em> and <em>LcMYB2539</em>), while suppressing the transcription of microRNAs (<em>miR159</em>, <em>miR319</em>, <em>miR828</em> and <em>miR858</em>) that mediate MYB degradation.

Unfortunately, rapid pericarp browning of litchi fruit after harvest considerably reduces its commercial value. In this study, litchi fruit were treated with gallic acid as a polyphenol with strong antioxidant properties, and then stored at ambient temperature (23 ± 1 °C). It was found that treatment with 5 mmol L⁻¹ gallic acid significantly maintained anthocyanin content and delayed pericarp browning during storage at ambient temperature. Compared with non-gallic acid-treated (control) fruit, the gallic acid-treated fruit showed higher red color value, ATP and energy levels, flavonoid and anthocyanin contents, lower accumulation of H₂O₂ and higher antioxidant capacity during storage, in agreement with higher activities of antioxidant enzymes (superoxide dismutase and peroxidase), and reduced glutathione content. Furthermore, the transcript levels of the genes related to the anthocyanin biosynthesis pathway, such as <em>LcPAL</em>, <em>LcCHS1</em>, <em>LcANS1</em>, <em>LcANS2</em>, <em>LcUFGT3,</em> and <em>LcUFGT4</em>, were significantly increased in the pericarp of the gallic acid-treated litchi during storage at ambient temperature.

In this study, blackberries and blueberries were packed in modified humidity clamshells (named as LV, for low-vented), with an opening ratio 6.43 times lower than that in commercially available clamshells (COM). Also, the antifungal effect of the thymol, an essential oil, microencapsulated in a pectin-alginate matrix as a controlled-release system was assayed. Results show that relative humidity within LV clamshells remained higher and less variable than in COM clamshells, which led to significantly lower weight loss in both crops. Blueberry firmness, shriveling and marketability were positively impacted by storage in LV clamshells, and the inclusion of a microencapsulated thymol sachet successfully reduced postharvest decay. Our results indicate that these two tools could be used to extend blueberry shelf life, with their combination yielding the most optimal results. However, the same strategies were ineffective for blackberry quality maintenance. After exposure to thymol, more decay was observed, whereas firmness, shrivel and marketability were not affected either by clamshell vent area or thymol treatment.
