“…Therefore, optimal lighting conditions and cultivars with a higher photosynthetic efficiency should be selected for sustainable crop production. Insights from plant photoresponses to different PPFD levels can be utilized to optimize energy efficiency [3,25]. For purslane, similar to lettuce [16], the light intensity linearly influences dry weight in both cultivars, but the photosynthetic efficiency differs, as indicated by the steeper slope of dependence between PPFD and dry weight for the green cultivar compared to the golden cultivar.…”

“…Leafy vegetables rich in vitamins, minerals, fibers, and antioxidants account for over half of indoor farming operations worldwide [2]. CEA has great potential for improving vegetable productivity, nutritional quality, and food insecurity, but it is energy-intensive [2,3]. Light, temperature, humidity, and plant hydroponic nutrition must be controlled and this is an energy-demanding process.…”

This study aims to evaluate the impacts of the lighting photosynthetic photon flux density (PPFD) on the growth, photosynthesis, and antioxidant response of common purslane (Portulaca oleracea) cultivars to determine energy-efficient lighting strategies for CEA. Green and golden purslane cultivars were cultivated in CEA chambers and four experimental treatments consisting of PPFDs of 150, 200, 250, and 300 ± 10 µmol m−2s−1 were performed, representing daily light integrals (DLIs) of 8.64–17.28 mol m−2d−1 throughout a 16 h photoperiod. The results show that photoresponses to light PPFDs are cultivar-specific. The green cultivar accumulates 174% more dry weight at 300 PPFD compared to the golden cultivar, and also has a higher LUE, but a lower ETR. Dry weight accumulation, plant height, and leaf area dependence on light intensity do not highlight the economic significance of light PPFD/DLI. The derivative parameter (Δ fresh weight (%)/ΔDLI %) more efficiently explains how the percentage increase in DLI due to an increased PPFD affects the percentage of biomass gain between these PPFD treatments. For both cultivars, the relative fresh weight gain is maximal when the lighting PPFD increases from 200 to 250 µmol m−2s−1 and declines with PPFD increases from 250 to 300.

The light emitting diodes have small dimension, physical strength, stable narrow spectrum, low temperature, versatile longevity, and high radiation efficiency and regulate morphogenesis, photoperiodism, flowering stimulus, photoreceptors, and biometabolism in the growing plant in a controlled environment plant growth chamber. The stable wavelength of electromagnetic light spectrum is received by the plant photoreceptors such as phytochrome, cryptochrome, phototropin, zeitlupe family protein, ultraviolet resistance locus 8 (UVR8) stimulates photomorphogenesis and biochemical pathway in the plant through soilless culture in a closed system. The mechanism of light emission is controlled with light factors like quality and quantity in the closed system. The light radiation regulates the long day photoperiodism (16 h day and 8 h night) through 400–700 nm photosynthetic active radiation (PAR) and 7.1–380 μmol m–2 s–1 photon flux density in the developing plant for continuing morphogenetic and metabolic process. The light transmission with variable wavelengths of 320–400 nm UVA, 400–500 nm blue, 500–600 nm green, 600–700 nm red, 700–750 nm far-red influences the cellular, molecular, and biochemical processes in the growing plant. The total and net energy production must be investigated with respect to effect of light and the plants raised in tissue culture, breeding, and gene manipulation under closed system.

“…Crop production in indoor or vertical farms offers the opportunity to fully shape plant growth due to complete environmental control (SharathKumar et al, 2020). In this regard, the quantity, quality and periodicity of light is important (de Carbonnel et al, 2022). In vertical farms, sole source lighting, such as light emitting diodes (LED), is substituted for sunlight (Oh and Lu, 2022).…”

There is an intricate relationship between the spectral composition of light, plant photosynthetic performance and biomass accumulation. The interaction between plants and the ambient light environment is not only crop-specific but also crucial for maximized yield and nutritional quality. The emergence of LED technology introduced a unique avenue for manipulating the light spectrum, offering new and continued possibilities for optimizing growth conditions. With a focus on tomato cultivation under sole-source lighting, we have investigated the impact of blue spectral quality (waveband composition) on growth and nutritional value of dwarf tomato. Notably, our study revealed that distinct wavebands of blue light (400 nm, 420 nm and 450 nm) can influence the net photosynthetic rate despite unaltered photochemical efficiency. Our research uncovered a correlation whereby shorter wavelengths of blue light increased leaf area, while longer blue wavelengths contributed to greater harvest indices. In addition, we identified a specific blue peak wavelength, 450 nm, that significantly affected chlorophyll composition in leaves and ascorbate levels in fruits. Through these findings, we call attention to the notion that blue spectral quality has a role in shaping both yield and nutritional attributes of dwarf tomato, such as ‘Micro Tom’, under sole-source lighting. Overall, our research provides valuable insight into the nuanced interplay between light spectrum, plant physiology, and horticultural outcome.
