“…aimed to understand the potential enhancement of carotenoids in petal tissue of two different cultivars of Tagetes tenuifolia under different light treatments (Table S1). The experimental lighting included a fluorescent treatment and different blue and red LED compositions (R:B in the range 10:90, 20:80, and 40:60) 81 . Results showed that LED lighting treatments positively affected carotenoid content in both cultivars.…”

“…80 Although many studies in recent years have focused on assessing the content of specialized metabolites in edible flowers, only a few studies have investigated the effects of artificial indoor LED lighting on the accumulation of bioactive compounds. In particular, Kopsell et al 81 aimed to understand the potential enhancement of carotenoids in petal tissue of two different cultivars of Tagetes tenuifolia under different light treatments (Table S1). The experimental lighting included a fluorescent treatment and different blue and red LED compositions (R:B in the range 10:90, 20:80, and 40:60).…”

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.
