“…Increased accumulation of plant metabolites (e.g., soluble sugars) was observed in the presence of red-blue LED. Natural daylight supplemented with red-blue LEDs increased the soluble sugars and organic acids in different crops (Samuolienė et al 2012b;Lin et al 2013;Samuolienė et al 2013;Dong et al 2014;Choi et al 2015;Xie et al 2016;Hasan et al 2017). In melon, Cui et al (2017) showed red:blue LED to be the most effective in increasing soluble sugar content.…”

“…Blue LEDs (450-470 nm) combined with red LEDs also increased the photosynthetic capacity and plant biomass in tomato, cucumber and pepper transplants (Hernández & Kubota 2012;Samuolienė et al 2012a). Furthermore, single or mixed blue and red LEDs improved the quality and yield of vegetables and fruit when compared with white fluorescent or solar light (Hao et al 2012;Dong et al 2014;Choi et al 2015;Li et al 2016;Xie et al 2016;Nadalini et al 2017). As blue and red light control the rates of photosynthesis through the opening and/or closing of stomata, their effect on plant biomass or yield was anticipated (Sabzalian et al 2014).…”

Melon (Cucumis melo L.) is a high-value fruit in Thailand, usually grown in plastic houses where light could become a major limiting growth factor. This study used melon cultivar ‘#120’ (orange flesh) grown in a plastic house under natural daylight (NDL, control) and with supplementary lighting using light emitting diodes (LEDs) of a combination of red 630 nm, red 660 nm, blue 450 nm, blue 460 nm, white 14000 K, UV 410 nm and IR 730 nm (LED1) or a combination of red 630 nm, red 660 nm, blue 450 nm and blue 460 nm (LED2) applied for 12 h from 6:00 pm to 6:00 am. These lighting treatments were combined with NPK fertilization using complete fertilizer 15–15–15 (N–P2O5–K2O) at 5 g, 7 g (recommended rate) or 9 g per plant. Results showed that LED2 combined with 9 g 15–15–15 was the most effective in increasing plant height, chlorophyll content (SPAD index), fruit size and mass, and peel and flesh thickness. The fruit also developed the desired lighter color (higher L* and lower a* coordinates) and were the firmest and sweetest (highest soluble solids content and lowest titratable acidity) among all treatments.

“…Although there are many reports on light regulating lycopene accumulation, how blue light affects lycopene content in undetached tomato is not well understood. The only observation worthy of mention in this regard is that the over expression of the blue light receptor CYR1a resulted in elevated lycopene content in tomato (Liu et al 2017), and that lycopene content continuously increased from 45 to 60 days after anthesis under 2R1B treatment, i.e., when the red (660 nm):blue (460 nm) ratio was 2:1 (Xie et al 2016).…”

Lycopene, one of the strongest natural antioxidants known and the main carotene in ripe tomato, is very important for human health. Light is well known to be one of the most important environmental stimuli influencing lycopene biosynthesis; specifically, red light induces higher lycopene content in tomato. However, whether blue light promotes lycopene synthesis remains elusive and exactly how light stimulation promotes lycopene synthesis remains unclear. We applied supplemental blue and red lighting on tomato plants at anthesis to monitor the effect of supplemental blue and red lighting on lycopene synthesis. Our results showed that supplemental blue/red lighting induced higher lycopene content in tomato fruits; furthermore, we found that the expression of key genes in the lycopene synthesis pathway was induced by supplemented blue/red light. The expression of light signaling components, such as red-light receptor phytochromes (PHYs), blue-light receptor cryptochromes (CRYs) and light interaction factors, phytochrome-interacting factors (PIFs) and ELONGATED HYPOCOTYL 5 (HY5) were up-or down-regulated by blue/red lighting. Thus, blue and red light increased lycopene content in tomatoes by inducing light receptors that modulate HY5 and PIFs activation to mediate phytoene synthase 1 (PSY1) gene expression. These results provide a sound theoretical basis for further elucidation of the light regulating mechanism of lycopene synthesis in tomatoes, and for instituting a new generation of technological innovations for the enhancement of lycopene accumulation in crop production.

“…Among the different LEDs, red LED irradiation enhanced β-carotene accumulation in pea plants [ 84 ]. Other studies reported that red LED irradiation resulted in an increase in β-cryptoxanthin content in citrus fruits [ 156 ] and lycopene content in tomatoes [ 157 ]. The duration of LED irradiation affected total carotenoid content and carotenoid biosynthesis in the growing plants.…”

Application of Light-Emitting Diodes for Improving the Nutritional Quality and Bioactive Compound Levels of Some Crops and Medicinal Plants

Light is a key factor that affects phytochemical synthesis and accumulation in plants. Due to limitations of the environment or cultivated land, there is an urgent need to develop indoor cultivation systems to obtain higher yields with increased phytochemical concentrations using convenient light sources. Light-emitting diodes (LEDs) have several advantages, including consumption of lesser power, longer half-life, higher efficacy, and wider variation in the spectral wavelength than traditional light sources; therefore, these devices are preferred for in vitro culture and indoor plant growth. Moreover, LED irradiation of seedlings enhances plant biomass, nutrient and secondary metabolite levels, and antioxidant properties. Specifically, red and blue LED irradiation exerts strong effects on photosynthesis, stomatal functioning, phototropism, photomorphogenesis, and photosynthetic pigment levels. Additionally, ex vitro plantlet development and acclimatization can be enhanced by regulating the spectral properties of LEDs. Applying an appropriate LED spectral wavelength significantly increases antioxidant enzyme activity in plants, thereby enhancing the cell defense system and providing protection from oxidative damage. Since different plant species respond differently to lighting in the cultivation environment, it is necessary to evaluate specific wavebands before large-scale LED application for controlled in vitro plant growth. This review focuses on the most recent advances and applications of LEDs for in vitro culture organogenesis. The mechanisms underlying the production of different phytochemicals, including phenolics, flavonoids, carotenoids, anthocyanins, and antioxidant enzymes, have also been discussed.
