“…Red and blue light are confirmed to have opposite effects. As far as root length is concerned, the lack of difference observed in our experiment would seem to conflict with results by Benincasa et al [18], who found that the monochromatic red light significantly increased root length. However, in that experiment, seeds were sprouted on sterile cotton, exposing root to the direct light.…”

“…Data on shoot yield and leaf shape as a function of light treatment appear in line with evidence obtained for several other species and einkorn wheatgrass [18,22,36,40]. Red and blue light are confirmed to have opposite effects.…”

“…In particular, blue light is necessary for photomorphogenesis, involving cryptochromes and phototropins, and reduces cell expansion and promotes a certain plant dwarfing [10,16,22,40]. On the other hand, red light causes pseudo-stem elongation in wheatgrass and favors leaf elongation in wheat, like in many vegetable crops [16,18,22,36,40]. Moreover, such long leaves prostrated, losing the erectophile arrangement ( Figure 2).…”

“…To date, researchers have mainly focused their studies on the impact on plants of different combinations of red and blue light [3]. As for microgreens, the effects of the light spectrum have been studied for several species, including einkorn wheatgrass [16][17][18]. In particular, 1-2-week old shoots of einkorn seedlings, mainly used for the production of juices, showed very high polyphenol, phenolic acid, and antioxidant content [19,20].…”

Furthermore, Benincasa et al [18] investigated the effect of light spectrum on wheatgrass that was obtained by sprouting grains with distilled water, highlighting its impact on phenolic content and antioxidant activities.…”

The use of Light Emitting Diode (LED) lights in microscale vegetable production is more and more widespread. In this context, the effect of light spectrum on photosynthesis, growth, shoot yield, pigment content, and nutritional status of einkorn seedlings (Triticum monococcum L. ssp. monococcum), germinated and grown in a nutrient solution, was investigated. Plants were subjected to six different LED light treatments, all having a photon flux density (PFD) of 200 μmol m−2 s−1. Two light treatments were monochromatic (red or blue), three dichromatic (blue and red in the proportion), and one of a wider spectrum (selected as a control). All the light treatments affected the morphological, biochemical, and nutritional status of einkorn seedlings. Overall, the dichromatic treatments were the most effective in stimulating biomass production, CO2 assimilation, and evapotranspiration, as well as contents in chlorophyll a and b and carotenoids, and additionally nitrogen, phosphorous, manganese, iron, and zinc. These results are of relevance for the beneficial effects of dichromatic LED treatments in maximizing einkorn shoot yield and nutritional values, and in limiting energy consumption in indoor cultivation.
