“…These results indicate that R light may have promoted the accumulation of Chl and total carotenoid content in water spinach. Similar effects have been reported in cucumber (Wang et al, 2009), tobacco (Yang et al, 2017), and lettuce (Johkan et al, 2010;Heo et al, 2012). On the other hand, an increase in Chl a/b was recorded under B light treatment.…”

“…In this study, plant growth was significantly influenced by light quality. Stem FW significantly increased under R light treatment, and this phenomenon was largely attributable to stem elongation (Table 1) stem elongation has been reported in some plant species, such as tobacco, pepper, and chrysanthemum (Schuerger et al, 1997;Kim et al, 2004;Yang et al, 2017). In contrast, leaf FW was greatest under RBFr light treatment, and this was probably due to the larger leaf area (Table 1).…”

Light quality is a critical factor that affects plant quality, including phytochemical accumulation and marketable characteristics, in closed-type plant production systems. The purpose of this study was to determine the appropriate light quality for production of good quality water spinach in terms of its appearance and accumulation of phytochemicals in an artificial environment. Plants were hydroponically cultured under five different light quality conditions: red, blue, green, red and blue (as a control), and red and blue with far red at a photosynthetic photon flux density of 200 µmol•m-2 •s-1 for 14 days after transplantation. Shoot (stem and leaf) fresh weights (FW) under red-containing light conditions increased more than 39.7% compared to that under monochromatic blue light, and monochromatic red light produced significantly higher stem FW but lower leaf FW compared to that under blue-containing light conditions. Monochromatic blue light significantly increased the antioxidant activity capacity in leaves and stems more than 210.0% compared to other treatments. However, blue-containing light significantly stimulated physiological disorder (intumescence injury) in stems and suppressed stem elongation compared to monochromatic red or green light. Monochromatic red light reduced the number of intumescent lesions by 95.8% and enhanced stem elongation compared to control. These findings suggest that red-rich light promotes growth of water spinach with less intumescence.

“…The exception was green-and purple-leaved basil, in which red light was less favourable than white light for chlorophyll accumulation. Previous studies indicated that blue light stimulates and red light inhibits chlorophyll synthesis in Chinese cabbage and grape (Poudel et al, 2008); however, the opposite trend has been shown in Nicotiana tabacum (Yiang et al, 2017).…”

Growth, morphology and accumulation of flavonoid compounds in green-and purple-leaved sweet basil (Ocimum basilicum L.), lamb's lettuce (Valerianella locusta (L.) Laterr.) and garden rocket (Eruca sativa L.) grown in a greenhouse under natural day light supplemented with white, blue (440 nm) and red (660 nm) light-emitting diodes (LEDs), all at 130 µmol m -2 s -1 , were studied in winter time. Under white and red LED lights, fresh weights of above-ground parts of lamb's lettuce and garden rocket were the highest, whereas under blue light they were the lowest, in comparison to the control (natural light). For green-and purple-leaved basil no significant differences in biomass production were observed when different light spectra qualities were applied. Supplementation of daily light with blue light resulted in more compact growth of green-leaved basil, as compared to plants grown under natural light and those supplemented with white and red lights. A non-destructive method using an optical sensor was used for evaluation of flavonol, anthocyanin and chlorophyll indexes in plants. Blue light led to significantly increased flavonol index in both green-and purple-leaved basil, lamb's lettuce and garden rocket plants.

“…The P n of the plants irradiated with a G510 light (peak wavelength: 510 nm; bandwidth at half peak height: 18 nm) was the highest among all of the light sources [6]. Many plant processes are regulated by the wavelength of light experienced during growth, including seed germination, photomorphogenesis, photosynthesis, carbon and nitrogen metabolism, biomass accumulation, chloroplast ultrastructure, and leaf anatomical structure [7][8][9][10][11][12]. Studies have shown that the ratio of red (R) light to far-R light regulates the flowering time of Arabidopsis, providing evidence for the existence of wavelength-specific pathways in plant flowering times [13].…”

Background: The optimized illumination of plants using light-emitting diodes (LEDs) is beneficial to their photosynthetic performance, and in recent years, LEDs have been widely used in horticultural facilities. However, there are significant differences in the responses of different crops to different wavelengths of light. Thus, the influence of artificial light on photosynthesis requires further investigation to provide theoretical guidelines for the light environments used in industrial crop production. In this study, we tested the effects of different LEDs (white, W; blue, B; green, G; yellow, Y; and red, R) with the same photon flux density (300 μmol/m 2 •s) on the growth, development, photosynthesis, chlorophyll fluorescence characteristics, leaf structure, and chloroplast ultrastructure of Welsh onion (Allium fistulosum L.) plants. Results: Plants in the W and B treatments had significantly higher height, leaf area, and fresh weight than those in the other treatments. The photosynthetic pigment content and net photosynthetic rate (P n) in the W treatment were significantly higher than those in the monochromatic light treatments, the transpiration rate (E) and stomatal conductance (G s) were the highest in the B treatment, and the intercellular CO 2 concentration (C i) was the highest in the Y treatment. The non-photochemical quenching coefficient (NPQ) was the highest in the Y treatment, but the other chlorophyll fluorescence characteristics differed among treatments in the following order: W > B > R > G > Y. This includes the maximum photochemical efficiency of photosystem II (PSII) under dark adaptation (Fv/Fm), maximum photochemical efficiency of PSII under light adaptation (Fv′/Fm′), photochemical quenching coefficient (qP), actual photochemical efficiency (ΦPSII), and apparent electron transport rate (ETR). Finally, the leaf structure and chloroplast ultrastructure showed the most complete development in the B treatment. Conclusions: White and blue light significantly improved the photosynthetic efficiency of Welsh onions, whereas yellow light reduced the photosynthetic efficiency.
