“…On the other hand, when LED light treatments were compared, the internodes of plants grown in RL were larger than those grown in RWL. This is consistent with previous studies in lettuce (Hirai et al 2006) and soybean (Fang et al 2020;Ma et al 2018). The internodal length of plants grown in BL was also not statistically different from that of plants grown in RWL or RL.…”

“…The internodal length of plants grown in BL was also not statistically different from that of plants grown in RWL or RL. There are some conflicting results regarding the effects of red light and blue light on morphological traits because they differ among species, genotypes, and growth conditions (Dougher and Bugbee 2004;Hirai et al 2006;Hitz et al 2019;Kendrick and Kronenberg 1986;Kong et al 201;Ma et al 2018).…”

Light intensity and spectral quality determine photosynthesis and thus plant growth and development. Both parameters, collectively referred to as the light environment, influence the composition and structure of the photosystem II, defining energy partitioning. This partitioning is the destination of the absorbed energy to photochemical and dissipative processes and is measured by quantum yield parameters. The aim of this study was to evaluate the photosynthetic performance of two soybean genotypes under four light environments with different spectral qualities (white light, red light-enriched white light, blue light, and red light) and the same energy flux. It was observed that plants growing only in red light had lower photosynthetic efficiency and higher photodamage after prolonged exposure. This phenomenon, called "red-light syndrome"; varied depending on the soybean genotype analyzed. Furthermore, it was found that spectral deficiency during leaf development has the main effect on photosystem functional capacity. Finally, a multivariate analysis of the energy partitioning parameters provided insight into the relevance of constitutive thermal dissipation processes in the plant acclimation to different light environments.

“…However, red light strongly alters morphology and physiology without showing positive effects on secondary metabolites (Zhang et al, 2020). A large number of photophysiological studies have verified the importance of the combination of red and blue light for improving plant growth and nutritional quality compared with than monochromatic light in crops such as lettuce, cucumber, soybean seedlings, and pak choi (Chen and Yang, 2018;Ma et al, 2018;Song et al, 2020).…”

The aim of the present study was to evaluate the effects of alternating red (660 nm) and blue (460 nm) light on the growth and nutritional quality of two-leaf-color pak choi (Brassica campestris L. ssp. chinensis var. communis). Four light treatments (supplemental alternating red and blue light with intervals of 0, 1, 2, and 4 hours, with a monochromatic light intensity of 100 μmol·m−2·s−1 and a cumulative lighting time of 16 hours per day) were conducted in a greenhouse under identical ambient light conditions (90 to 120 μmol·m−2·s−1 at 12:00 am) for 10 days before green- and red-leaf pak choi were harvested. The results showed that the two-leaf-color pak choi receiving alternating red and blue light exhibited more compact canopies and wider leaves than those under the control treatment, which was attributed to the shade avoidance syndrome of plants. The present study indicated that the biomass of green-leaf pak choi was much higher than that of red-leaf pak choi, but the nutritional quality of green-leaf pak choi was lower than that of red-leaf pak choi, and seemingly indicating that the regulation of metabolism for pak choi was species specific under light exposure. The trends of both biomass and the soluble sugar content were highest under the 1-hour treatment. The contents of chlorophyll a and total chlorophyll in both cultivars (green- and red-leaf pak choi) were significantly increased compared with control, without significant differences among the 1-, 2-, and 4-hour treatments, whereas chlorophyll b exhibited no significant difference in any treatment. Alternating red- and blue-light treatment significantly affected the carotenoid content, but different trends in green- and red-leaf pak choi were observed, with the highest contents being detected under the 1-hour and 4-hour treatments, respectively. With increasing time intervals, the highest soluble protein contents in two-leaf-color pak choi were observed in the 4-hour treatment, whereas nitrate contents were significantly decreased in the 4-hour treatment. Compared with 0 hours, the contents of vitamin C, phenolic compounds, flavonoids, and anthocyanins in two-leaf-color pak choi were significantly increased, but no significant differences were observed in vitamin C, phenolic compounds, and flavonoids among the 1-, 2-, and 4-hour treatments, similar to what was found for the anthocyanin content of green-leaf pak choi. However, the content of anthocyanins in red-leaf pak choi gradually increased with increasing time intervals, with the highest content being found in the 4-hour treatment. Supplemental alternating red and blue light slightly increased the antioxidant capacity [1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging rate and antioxidant power], but no significant differences were observed after 1, 2, and 4 hours of treatment. Taken together, treatment with an interval of 1 hour was the most effective for increasing the biomass of pak choi in this study, but treatment with a 4-hour interval should be considered to enhance the accumulation of health-promoting compounds.
