“…Light is not only the crucial factor for plant development during growth phase but can also infl uence the postharvest behaviour when fruits and vegetables are irradiated during storage. Some recent studies have shown that the application of LEDs during storage can preserve and even improve the nutritional quality of fruits (26) and vegetables (20,27,28). The results are nevertheless inconclusive and detailed analysis of LED light spectra on postharvest physiology is still lacking.…”

SummaryThe objective of this study is to investigate the eff ects of irradiation from light-emitt ing diodes (LEDs) on several fruits during storage. To improve storage and increase the contents of some bioactive compounds, apple, tomato and red bell pepper fruits were exposed to yellow light emitt ed from the diodes at 590 nm. The contents of ascorbic acid, total phenolics, total fl avonoids and several pigments were investigated, along with the antioxidant potential. The colour parameters (L*, a* and b*) and fi rmness of the fruit were also determined. Aft er 7 days of LED light irradiation, there was signifi cantly higher total phenolic content and antioxidant potential in apple peel extracts. The irradiated fruit of tomato had signifi cantly higher levels of total phenolic compounds, and the fruit of red bell pepper had signifi cantly higher antioxidant potential. LED light had no eff ects on the colour parameters, although there was a tendency to accelerate colour development. Apple fruit irradiated with LED light was signifi cantly less fi rm. Among twelve analysed pigments, signifi cantly more β-carotene was detected in LED light-irradiated apple and bell pepper fruit, more α-tocopherol and γ-tocopherol in bell pepper fruit, and more lutein in apple peel and bell pepper fruit. The applied LED light slightly accelerated the ripening of the studied fruit, and aff ected the synthesis of some of the secondary metabolites.

“…We previously reported accumulation of stilbenic compound by LED light in grape berries (Ahn et al 2015). Although there have been several reports of induced resistance and resveratrol accumulation in response to UV irradiation (Adrian et al 2000;Bonomelli et al 2004;Choi 2012;Keller et al 2003;Kobayashi et al 2013;Wang et al 2010), there have been no previous investigations of the induction of resistance responses against B. cinerea in grapevine leaves in response to different LED light sources.…”

Inhibition of Botrytis cinerea and accumulation of stilbene compounds by light-emitting diodes of grapevine leaves and differential expression of defense-related genes

Grey mold (Botrytis cinerea) is one of the most common diseases to attack grapes, causing serious damage during grape production. In the present study, the effects of light-emitting diodes (LED) on the suppression of fungal growth, defense related gene expression and accumulation of stilbenic compounds were investigated. Irradiation with blue and red light inhibited lesion development relative to fluorescent light in detached leaves. Treatment of detached leaves with LED light, especially blue and red, resulted in accumulation of stilbenic compounds and differential expression of genes involved in defense response. Among five stilbenic compounds, concentrations of trans-and cispiceid were higher than those of trans-and cis-resveratrol, as well as piceatannol in both 'Campbell Early' and 'Kyoho' leaves treated with blue and red light. The gene expression of beta-1,3 glucanase (Glu), osmotin (OSM), pathogen-related protein 4a (PR4a), protease inhibitorlike protein (PILP), thaumatin-like protein (TLP), glutathione-S-transferase (GST), phenylalanine ammonialyase (PAL), chalcone synthase (CHS), and stilbene synthase (STS) were highly upregulated under blue and red LED light. The results reported here will facilitate development of alternative methods to enhance the accumulation of resveratrol compound and protect grapevine from fungal pathogen infections.

The stilbene profile in edible berries

2018

Edible berries are becoming increasingly popular to consume in fresh, dried, frozen or processed forms due to their high content and wide diversity of bioactive compounds with considerable health benefits. Among the wide variety of phytochemicals found in berries are stilbenes, which demonstrate a broad range of biological and pharmacological activities. Their content depends on many factors, including the cultivar, ripening stage, climatic conditions, agronomic management, storage conditions and postharvest management. However, the application of various abiotic and biotic external stimuli could be a strategy for increasing the production of stilbenes in edible berries. To date, several different elicitors, as inducers of plant secondary metabolite stilbenes, have been applied in different studies. This review focuses on the isolation and identification of stilbenes from edible berries and presents the influence of different external stimuli on their profile in grapes.
