“…Savvides et al [ 17 ], similar to the results obtained in this work, showed that the presence of blue light in LED lamps had a positive effect on the intensity of gas exchange and, consequently, photosynthesis in cucumber plants. Higher net carbon assimilation in plants of different species ( Pterocarya , lettuce, cherry radish, cherry tomato, einkorn) was recorded after treatment with blue light [ 43 ] and different combinations of blue and red light [ 45 , 46 ]. On the other hand, Lanoue et al [ 47 ] showed that the photosynthetic rate was similar irrespective of the light spectrum, while Yang et al [ 48 ] demonstrated that the net photosynthetic rate of plants lighted with blue light was lower compared to other light treatments.…”

The objective of this study was to evaluate the effect of the supplemental lighting of cucumber with sodium pressure lamps (HPSs) and light-emitting diodes (LEDs) on photosynthetic efficiency and yield in autumn–winter cultivation. Cucumber plants of the ‘Svyatogor’ F1 midi-cucumber parthenocarpic type cultivar were grown on mineral wool mats in three compartments, differing only in the type of light, i.e., (1) HPS top lighting (HPS) in the first compartment, (2) HPS top lighting and LED panel interlighting (HPS + LED) in the second compartment and (3) LED top lighting and inter-row LED panels (LED) in the third compartment. The photosynthetically active radiation was the same in each compartment. The study showed that the highest commercial yields of cucumber could be achieved under LED light (top and inter-row). The chlorophyll content in the leaf blade of younger leaves was higher in plants under LED lighting. This type of lighting also had a positive effect on the gas exchange of plants (net carbon assimilation, stomatal conductance, transpiration). LED and HPS + LED lighting increased the chlorophyll a fluorescence parameters, such as Fs, Fm’ and vitality index (PI), in both younger and older leaves, which also increased the fruit yield in the tested combinations.

“…Continuous illumination with red light LEDs has also been found to significantly promote increases in the contents of lycopene, beta carotene, phenolic acid, and flavonoids in postharvest tomato fruits (31), whereas significant increases in the contents of free amino acids in post-harvest tomato fruits have been detected in response to continuous illumination with blue light LEDs (32). In addition, the provision of red light LED lighting can improve the content of Mg, Ca, Cu, and other mineral elements in tomato fruits (19), and the sensory qualities of aroma and texture in fruits can be significantly enhanced in response to an increase far-red irradiation (33). In our previous studies, we have also found that exposing tomato plants to redblue light LEDs can improve the soluble sugar and soluble protein contents of fruits (34).…”

“…Light is an important environmental factor that regulates the activities of metabolite-related biochemical pathways during tomato ripening and plays an important role in determining tomato quality (16). Both the leaves and fruits of tomato contain photoreceptors, including phytochrome and cryptochrome (17,18), and appropriate illumination can promote the absorption of light and enhance the photosynthetic capacity of tomato (19). Moreover, light can contribute to promoting the absorption and transport of water and nutrients (20), thereby influencing metabolic processes and metabolite production (21).…”

Light is an important environmental factor that regulates the activity of metabolism-related biochemical pathways during tomato maturation. Using LED to improve lighting conditions during the process of tomato growth and development is a feasible and efficient method to improve the quality of tomato fruit. In this study, red and blue LEDs were used to supplement light on “MicroTom” tomato plants for different periods of time in the morning and evening, and the differences between the primary and secondary metabolites and other nutrient metabolites in the tomato fruit were analyzed using liquid chromatography and liquid chromatography mass spectrometry and other methods. Supplementing light in the morning promoted the accumulation of vitamin C, organic acids, amino acids, carotenoids, phenolic acids, and other health-promoting substances in the tomato fruits. Supplementing light in the evening significantly increased the content of sugars, flavonoids, and aromatic substances in tomato fruits, whereas the promoting effect of LED on the accumulation of amino acids and carotenoids was lower in the evening than in the morning. Both morning and evening light supplementation reduced the mineral content of fruit. In conclusion, morning light supplementation improved the nutritional quality of tomato fruits, while evening light supplementation improved their flavor.

“…The effects of environmental stress on ionome have been investigated in plants, including tomatoes [ 106 , 107 , 108 , 109 , 110 ]. There have so far been studies on the effects of light quality on some mineral elements in horticultural crops, including tomatoes [ 111 , 112 ], yet no reports about ionomic profile changes in response to different light qualities in tomatoes. Therefore, this study aimed to evaluate the influence of light quality on element accumulation and distribution in tomatoes using ionomics.…”

Light quality affects plant growth and the functional component accumulation of fruits. However, there is little knowledge of the effects of light quality based on multiomics profiles. This study combined transcriptomic, ionomic, and metabolomic analyses to elucidate the effects of light quality on metabolism and gene expression in tomato fruit. Micro-Tom plants were grown under blue or red light-emitting diode light for 16 h daily after anthesis. White fluorescent light was used as a reference. The metabolite and element concentrations and the expression of genes markedly changed in response to blue and red light. Based on the metabolomic analysis, amino acid metabolism and secondary metabolite biosynthesis were active in blue light treatment. According to transcriptomic analysis, differentially expressed genes in blue and red light treatments were enriched in the pathways of secondary metabolite biosynthesis, carbon fixation, and glycine, serine, and threonine metabolism, supporting the results of the metabolomic analysis. Ionomic analysis indicated that the element levels in fruits were more susceptible to changes in light quality than in leaves. The concentration of some ions containing Fe in fruits increased under red light compared to under blue light. The altered expression level of genes encoding metal ion-binding proteins, metal tolerance proteins, and metal transporters in response to blue and red light in the transcriptomic analysis contributes to changes in the ionomic profiles of tomato fruit.
