“…114 In contrast, Allium sativum showed a significantly higher accumulation of phenols under monochromatic red light applied with a photoperiod of 16 h day −1 compared to monochromatic blue, green and white light. 115 In the case of Coriandrum sativum, monochromatic blue allowed the highest increase in phenol content compared with monochromatic red and green, as well as with red and blue, and red, blue, and far-red combinations. 116 Both in A. sativum and C. sativum, monochromatic green light seems to have a limited effect on plant phenol accumulation.…”

Beyond vegetables: effects of indoor LED light on specialized metabolite biosynthesis in medicinal and aromatic plants, edible flowers, and microgreens

Specialized metabolites from plants are important for human health due to their antioxidant properties. Light is one of the main factors modulating the biosynthesis of specialized metabolites, determining the cascade response activated by photoreceptors and the consequent modulation of expressed genes and biosynthetic pathways. Recent developments in light emitting diode (LED) technology have enabled improvements in artificial light applications for horticulture. In particular, the possibility to select specific spectral light compositions, intensities and photoperiods has been associated with altered metabolite content in a variety of crops. This review aims to analyze the effects of indoor LED lighting recipes and management on the specialized metabolite content in different groups of crop plants (namely medicinal and aromatic plants, microgreens and edible flowers), focusing on the literature from the last 5 years. The literature collection produced a total of 40 papers, which were analyzed according to the effects of artificial LED lighting on the content of anthocyanins, carotenoids, phenols, tocopherols, glycosides, and terpenes, and ranked on a scale of 1 to 3. Most studies applied a combination of red and blue light (22%) or monochromatic blue (23%), with a 16 h day−1 photoperiod (78%) and an intensity greater than 200 μmol m−2 s−1 (77%). These treatment features were often the most efficient in enhancing specialized metabolite content, although large variations in performance were observed, according to the species considered and the compound analyzed. The review aims to provide valuable indications for the definition of the most promising spectral components toward the achievement of nutrient‐rich indoor‐grown products. © 2021 The Authors.

“…Many studies have tested the effect of light intensity and quality on sprout phytochemical content, with contrasting results depending on the PPFD (photosynthetic photon flux density) and on the specific wavelengths [ 18 , 32 , 33 ]. However, the general tendency is to have a higher quantity of antioxidants in light-grown sprouts compared to dark-grown ones [ 34 , 35 , 36 , 37 ], even if sprouts grown in the light can be smaller compared to those grown in the dark [ 38 ].…”

In the last decades, there has been a growing interest in the production of sprouts, since they are a highly nutritious food, particularly suitable for indoor farming in urban areas. Achieving sprout production in indoor systems requires an understanding of possible alterations induced by the microclimate. The aim of this study was to analyze the combined effect of presence/absence of light and high/low air relative humidity (RH) on mung bean sprouts. Morpho-anatomical development and functional anatomical traits in hypocotyl were quantified. The content of antioxidants, soluble sugars, and starch were measured for nutritional and functional purposes. Different RH regimes mainly induced morpho-anatomical modifications, while the presence/absence of light changed the content of antioxidant compounds. Increments in stele diameter at high RH suggest a higher water uptake and conductivity, compared to the low RH treatment; low RH and light induced anatomical traits improving plant water transport (reduced number of cortical layers) and increased the production of antioxidants. The overall results suggested that RH and light, already at the early stages of development, affect the plant’s nutritional value. Therefore, the combination of light and low RH allows the production of antioxidant-rich mung bean sprouts to be used as a food supplement.

“…Studies showed that stress can influence the release of polyphenols from vacuoles as well as the synthesis of new phenols; these data can support the premise that these metabolites are major biomarkers that can be used to highlight the influence of pollutants and different chemical or physical factors (irradiation) on plants (M. KOALA & al [24], B.G. BRASILEIRO & al [25], R.H. ARMON & O. HÄNNINEN [26], RAICIU D & al [27], RAICIU D & al [28]). Therefore, we decided to analyze the biochemical modifications that appeared in bean seedlings under the influence of the tested chemicals, because citoxicity is also surely associated with the alteration of metabolic processes (R. AZMAT & al [7]).…”

The phytotoxicity of eight dibrominated cinnamic acid derivatives on Phaseolus vulgaris was evaluated. Plant bioassays are usually used for ecotoxicity assessment and in the development of new pesticides, but they can also represent simple and inexpensive screening tools to identify well-tolerated substances before subjecting them to further more complex in vivo toxicity tests. Bean seeds were cultivated on filter paper impregnated with different concentrations of active substance (28.6 μg cm-2 , 57.3 μg cm-2 , 114.6 μg cm-2) and the development of the resulting seedlings was analyzed in comparison to a control group. Three aspects were observed: aspects of roots and seedlings growth, histo-anatomical changes induced in root tissues and alteration of polyphenols synthetic capacity. In most experimental cases, the exposure to the tested compounds inhibited the development of both roots and seedlings. In addition, some substances also caused histo-anatomical changes in the root tissues of bean seedlings. According to the results of the spectrophotometric determination, the total polyphenols content decreased after treatment for all the tested substances in comparison to the control, the reduction being directly proportional to the concentration of active substance. In conclusion, the experimental data revealed a certain degree of phytotoxicity for the investigated chemicals.
