Growth, nutritional quality, and energy use efficiency in two lettuce cultivars as influenced by white plus red versus red plus blue LEDs

Abstract: Red plus blue light-emitting diodes (LEDs) are commonly applied in plant factories with artificial lighting due to photosynthetic pigments, which absorb strongly in red and blue light regions of the spectrum. However, plants grown under natural environment are used to utilizing broad-wide spectrum by long-term evolution. In order to examine the effects of addition light added in red plus blue LEDs or white LEDs, green and purple leaf lettuces (Lactuca sativa L. cv. Lvdie and Ziya) were hydroponically cultivate… Show more

“…Empirical data reveals that red-light benefits carbon dioxide (CO2) assimilation rate, while green-and blue-lights impair CO2 assimilation in low and moderate to high light conditions, respectively (Landi et al, 2020). A large number of studies have tested the effects of different light wavelengths on morphological growth, dry mass accumulation, gas exchange, and photosynthesis ( Kang et al, 2016;Claypool and Lieth, 2020;Yan et al, 2020). Results from these studies have limited application meaning unless they were tested in a widebandwidth spectrum (Landi et al, 2020).…”

“…In purple leaf lettuce ( Lactuca sativa L. cv. Ziya) grown under WL plus RL, no significant differences were observed in Vit C content compared with WL [ 76 ]. In lettuce plants under continuous light for 12 days, the ratio 25RL/75BL increased the Vit C level mainly by promoting Vit C regeneration rather than its biosynthesis.…”

“…According to the report of Ajdanian et al [26] , the more the percentage of the blue light, the more the amount of chlorophyll was considerably increased based on 1% LSD. The highest amount of chlorophyll a, b and total was observed under 60R:40B treatment with values of 9.4, 5.68, and 15.09 mg/g FW leaf, respectively [26] , but no remarkable differences were observed in chlorophyll contents of two lettuce cultivars grown under red plus blue LEDs and white plus red LEDs in some research [37] .…”
