Physicochemical Composition of Buckwheat Microgreens Grown under Different Light Conditions

Effect of Different Ratios of Blue and Red LED Light on Brassicaceae Microgreens under a Controlled Environment

“…Some studies have confirmed the positive effect of blue light on the accumulation of mineral nutrients in various microgreens [ 21 , 38 , 39 , 40 ]. Moreover, other studies have reported a positive red light effect on mineral nutrient content in buckwheat and beet microgreens [ 28 , 38 ]. These studies have mainly investigated short-term blue light as supplemental to other illumination or the long-term effects of monochromatic blue and red light or their dichromatic illumination with one ratio.…”

“…However, there is still a lack of information on how manipulation of the light spectrum affects changes in the mineral element content of various leafy vegetables, and the available information is contradictory. Some studies have demonstrated the positive effect of short-term monochromatic blue light or its percentage in different light spectrum compositions on the mineral element content in plants [ 25 , 26 , 27 , 28 , 29 ]. Some authors have reported that red LED or its higher percentage in blue–red lighting increased some mineral nutrients in marigold [ 30 ], lettuce [ 31 ], and basil [ 24 ].…”

Blue and Red LED Illumination Improves Growth and Bioactive Compounds Contents in Acyanic and Cyanic Ocimum basilicum L. Microgreens

“…Improving their qualities is an exciting avenue of research and biotechnology, as properties of microgreens can be enhanced through various stimuli which may be synergic, while also easily available. Improvement of microgreens quality using LEDs has already been described in numerous species, such as rice [ 27 ], buckwheat [ 23 ], amaranth, pea, kale, broccoli, mustard, basil, borage, beet, parsley [ 25 ], basil [ 64 ], Brassica spp. [ 19 ], etc.…”

“…The effects of LED illumination in microgreen cultivation has been investigated in several species, such as Brassica oleracea , B. juncea , B. rapa [ 19 , 20 ], pea, broccoli, mustard, borage, amaranth, kale, beet, parsley [ 21 ], Valerianella locusta [ 22 ], buckwheat [ 23 ], Perilla frutescens [ 24 ], etc. In basil microgreens, research on light quality regarded the effect of red light supplementation on total phenolic content and antioxidant activity [ 21 ]; red, blue and far-red supplementation on antioxidant activity [ 25 ]; ultraviolet A (UV-A) supplementation on growth, phenolic, anthocyanin, ascorbate and tocopherol synthesis [ 24 ]; and blue light dosage on growth, ascorbate, total phenolic, anthocyanin, flavonoid contents and 2,2-diphenyl-1-picrylhydrazyl (DPPH) antioxidant activity [ 25 ].…”

Physicochemical, agronomical and microbiological evaluation of alternative growing media for the production of rapini (Brassica rapa L.) microgreens

“…Moreover, with the development of the urban farming industry, there is an increasing interest in their commercial production . Microgreens may be grown in greenhouses, or indoors, with artificial light sources, in the soil or, most commonly, in soil‐less systems, using organic or inorganic solid growing media or hydroponics . Despite the short growing cycle, the commercial production of microgreens requires particular attention, and the choice of the growing medium represents one of the most critical aspects of the production process.…”
