“…The quality and quantity of light can be manipulated to improve yield and the phytonutrient contents of leafy greens. Applying an appropriate LED spectral wavelength significantly increases antioxidant enzyme activity in plants [10], thereby enhancing cell defence systems and providing protection from oxidative damage. It is possible to optimize productivity and quality through the optimization of the lighting to align with the sensitivity curve of the photosensitive pigments in plants.…”

The effect of artificial lighting with different light spectra and photoperiods/daily light integrals (DLIs) on the yield, bioactive compounds and antioxidant capacity of the common ice plant (Mesembryanthemum crystallinum) was studied. Four-week-old seedlings were selected and subjected to four different light spectra made up of different combinations of blue (400–500 nm), green (500–600 nm) and red light (600–700 nm), with a total photosynthetic photon flux density (PPFD) of 180 µmol.m−2.s−1. Concurrently, the effect of the daily light integral (DLI) was also studied, with the light treatment photoperiod set at 18 h and 21 h. Biometric parameters such as fresh mass weight, leaf area, leaf width, and dry mass, together with plant metabolite contents such as total antioxidant capacity (TAC), vitamin C, chlorophyll a and b content, and total carotenoids and nitrates, were investigated. It was found that the plants grew better when exposed to light with a higher proportion of the red and blue spectrum, with the highest fresh mass of 68 g observed at a photoperiod of 18 h. On the other hand, green spectrum light was not found to yield any significant improvement in shoot weight, leaf area, or leaf size. It was also found that dry mass, chlorophyll b and nitrates were not influenced by the light spectrum but were influenced by the photoperiod duration. While both the dry mass and nitrate content increase as the photoperiod increases, a longer photoperiod had a negative effect on chlorophyll a, chlorophyll b and total carotenoids, with their content decreasing by as much 29% for chlorophyll a, 59% for chlorophyll b and 29% for total carotenoids. TAC content was seen to increase by more than 24% under the influence of 66% more green light, and 38% more under the 21 h photoperiod.

“…For example, constant illumination with monochromatic red light may result in plants with abnormal leaf structure and anatomy, as well as lower photosynthetic rates, compared to plants provided by a combination of red and blue light or composite white light (Hogewoning et al 2010). Plants exposed to monochromatic blue light for a long period may also be negatively affected, exhibiting impaired mesophyll conductance (Loreto et al 2009), and a lower photosynthetic rate (Kim et al 2004, Zhang et al 2021. Previous studies have demonstrated that a combination of different wavelengths of monochromatic light in the visible spectrum is needed for normal plant growth, development, and photosynthesis (Wang et al 2016).…”

The ice plant (Mesembryanthemum crystallinum L.) is a halophyte that could become an alternative crop because of its interest as a functional food and its adaptation to high‐saline soils. In this work, leaves from wild ice plants were compared with their cultivated counterparts in a soilless system at different salinities and light exposures for assessing growth parameters, moisture, fatty acid profiles, total carotenoids, phenolic compounds, vitamin C, antioxidant activity, and antiproliferative activity against the HT‐29 colorectal cancer cell line. Moisture ranged between 876 and 955 g kg−1, and wild plants contained higher proportions of α‐linolenic acid (58.7%–60.7% of total fatty acids) than cultivated ones (20.4%–36.6%). Vitamin C ranged between 819 and 1143 mg kg−1 fresh leaves. Higher salinity led to a larger production of carotenoids, whereas plant mass, total phenolic content, and antioxidant activity increased in plants grown using L8 NS1 and L8 AP67 lamps in comparison with white‐light ones. Phenolic profiles were assessed by LC coupled to a hybrid mass spectrometer Q‐Orbitrap. Total phenolic acid content was 3–4‐fold higher than that of flavonoids, and sinapic, p‐coumaric, gallic, 4‐hydroxybenzoic, and 2‐hydroxy‐4‐methoxybenzoic acids, as well as gallocatechin, occurred in all samples. Hydroalcoholic extracts of ice plant leaves showed dose‐ and time‐dependent antiproliferative activity against the HT‐29 human colorectal cancer cell line, and GI50 was between 920 and 977 μg mL−1 of plant extract. This work contributes to improving knowledge about the growth parameters, phytochemical profiles, and biological activities of wild and cultivated ice plants.
