“…albogabra (kale) grown under a prolonged light (16 h day/8 h night) show decreased height, larger cotyledons, and greater dry matter compared to sprouts grown under short-day photoperiods [29]. Mature B. oleracea plants subjected to continuous illumination during postharvest storage display delayed yellowing and chlorophyll degradation [17]. In this study, various day-length regimes (8 h day/16 h night, 12 h day/12 h night, 16 h day/8 h night, and 24 h day/0 h night) were implemented during a whole period of B. juncea growth and infection by A. brassicicola, which obviously affected leaf morphology and necroses formation.…”

“…In lettuce, which is less sensitive to CL than tomato, photooxidative stress induced by CL caused enhanced production of reactive oxygen species (ROS) and lipid peroxidation, but biomass gain was also observed [16]. Recent research has revealed that exposing broccoli to continuous white light delays its yellowing and chlorophyll degradation during postharvest storage [17]. Thus, manipulating day length can be used as a new tool of modern agriculture, especially in controlled-environment plant factories [14].…”

The main goal of growing plants under various photoperiods is to optimize photosynthesis for using the effect of day length that often acts on plants in combination with biotic and/or abiotic stresses. In this study, Brassica juncea plants were grown under four different day-length regimes, namely., 8 h day/16 h night, 12 h day/12 h night, 16 h day/8 h night, and continuous light, and were infected with a necrotrophic fungus Alternaria brassicicola. The development of necroses on B. juncea leaves was strongly influenced by leaf position and day length. The largest necroses were formed on plants grown under a 16 h day/8 h night photoperiod at 72 h post-inoculation (hpi). The implemented day-length regimes had a great impact on leaf morphology in response to A. brassicicola infection. They also influenced the chlorophyll and carotenoid contents and photosynthesis efficiency. Both the 1st (the oldest) and 3rd infected leaves showed significantly higher minimal fluorescence (F0) compared to the control leaves. Significantly lower values of other investigated chlorophyll a fluorescence parameters, e.g., maximum quantum yield of photosystem II (Fv/Fm) and non-photochemical quenching (NPQ), were observed in both infected leaves compared to the control, especially at 72 hpi. The oldest infected leaf, of approximately 30% of the B. juncea plants, grown under long-day and continuous light conditions showed a ‘green island’ phenotype in the form of a green ring surrounding an area of necrosis at 48 hpi. This phenomenon was also reflected in changes in the chloroplast’s ultrastructure and accelerated senescence (yellowing) in the form of expanding chlorosis. Further research should investigate the mechanism and physiological aspects of ‘green islands’ formation in this pathosystem.

“…Similarly, light irradiation has been shown to preserve glucosinolate levels in cabbage, kale (Liu et al, 2015), and broccoli (Jin et al, 2015), during storage. Previous studies have suggested that the gene expressions involved in glucosinolate metabolism is regulated by light irradiation (Casajús et al, 2021;Schuster et al, 2006;Wang et al, 2021). In this study, higher expression levels of glucosinolate biosynthetic genes (CYP79F1, CYP79B2, and CYP79B3) and lower expression level of a glucosinolatedegraded gene (TGG1) compared with control samples were observed in light-treated baby mustard.…”

“…In addition, the effect of blue light treatment on inhibiting the decline of certain glucosinolates was less than that of other light treatments, which stems from the fact that blue light treatment cannot induce glucosinolate biosynthesis, but can only inhibit glucosinolate breakdown in baby mustard during storage. These findings indicate that the effect of light exposure on glucosinolate metabolism in post-harvest baby mustard depends on the wavelength (Casajús et al, 2021).…”

The ability of white, red, and blue irradiation to maintain sensory quality, health-promoting compounds, and antioxidant capacity, and regulate glucosinolate metabolism-related gene expression in post-harvest baby mustard was studied. Irradiation with 80 µmol m −2 s −1 extended the shelf life of post-harvest baby mustard. Irradiation delayed the increase in weight loss and the decrease in sensory parameter scores and the levels of ascorbic acid, total phenolics, glucosinolate, and antioxidant capacity during storage of baby mustard. Irradiation induced the expression of glucosinolate biosynthesis genes and inhibited glucosinolate degradation gene expression. The glucosinolate content and glucosinolate metabolism-related gene expression in post-harvest baby mustard were higher under white and red light irradiation compared with blue light irradiation. These findings indicate that irradiation (80 µmol m −2 s −1 ), especially of white and red light, is an effective technique for maintaining the sensory and nutritional qualities in post-harvest baby mustard stored at 20 • C.

Postharvest illumination is an emerging nonthermal preservation technique used to preserve the quality of vegetables. This review aimed to provide an insight into the effect, importance, and limitations of postharvest illumination by fluorescent and ultraviolet (UV) light on the physical and nutraceutical properties of vegetables. It presents the current information on the postharvest application of these two lightings based on the vegetable species. According to the existing studies, both photoperiod and continuous (low‐intensity) fluorescent lighting treatments were beneficial more toward preserving the quality (delaying senescence and deterioration) of postharvest vegetables, mainly leafy vegetables. However, inconsistent results are also possible with the light quality (intensity and duration) on the postharvest fluorescent lighting treatment. According to gathered information, both UV‐B and UV‐C postharvest irradiation has been beneficial in delaying senescence and chlorophyll degradation and inducing bioactive compounds accumulation in some vegetable species. UV‐C application is appeared to have a relatively steady effect on the postharvest storage of vegetables. But UV‐B irradiation effect on the postharvest quality of vegetables was appeared to be dose dependent and not stable. In conclusion, it is important to consider vegetable (species, cultivar, harvesting age, and intact or fresh‐cut), previous treatments/conditions, optimum postharvest lighting condition (illumination source, dose, intensity, and duration), and the storage condition (temperature and relative humidity) for a successful implementation of postharvest illumination. More research is required to explore the postharvest application of fluorescent and UV (UV‐A, UV‐B, UV‐C) irradiation on vegetables. Practical Applications Multiple research approaches have been taken to preserve the postharvest quality of vegetables while minimizing chemical preservation techniques. Postharvest illumination is a nonchemical preservation technique that has attained more interest due to the advantages it holds, such as being highly efficient and residue‐free. Fluorescent and UV lighting on harvested leafy and non‐leafy vegetables are beneficial in delaying senescence and chlorophyll degradation, preserving nutritional quality, and extending the shelf life. With the accessibility of more research data and innovative strategies, the future of postharvest illumination of fluorescent and UV maybe steer toward implementation on commercial scale vegetable production (e.g., during storage and/or transportation).
