“…2). This result agrees with previous studies (Madhana et al, 2014;Naing et al, 2016). Compared with CaLn, dry weight components (leaf, stem, and roots) were significantly affected by CeLn and CaLs, but the greatest affect was with CeLs (Table 1).…”

“…Bencze et al (2011) reported that CO 2 enrichment can enhance photosynthesis in tomatoes and peppers even under low-light conditions. Interestingly, combinations of CO 2 enrichment and supplementary lighting can result in greater positive effects on plant growth and yield than enhancement of either factor on its own (Labeke and Dambre, 1998;Naing et al, 2016). To the best of our knowledge, the effects of the combination of supplementary lighting and CO 2 enrichment in winter and spring on the growth of tomatoes have not been thoroughly investigated.…”

During the autumn/spring “off” season, yield and quality of tomatoes are often affected by insufficient CO2 and low light in greenhouse production. Although tomato is one of the most widely cultivated vegetables, few studies have investigated the interactive effects of supplementary light and CO2 enrichment on its growth, photosynthesis, yield, and fruit quality in greenhouse production. This study investigates the effects of supplementary light (200 ± 20 μmol·m–2·s–1) and CO2 enrichment (increases to about 800 μmol·mol–1), independently and in combination, on these parameters in autumn through spring tomato production. Compared with tomatoes grown under ambient CO2 concentrations and no supplementary light (CaLn), supplementary light (CaLs) and supplementary light and CO2 enrichment (CeLs) significantly promoted growth and dry weight accumulation. Meanwhile, CO2 enrichment (CeLn) and CaLs significantly improved photosynthetic pigment contents and net photosynthetic (Pn) rates, whereas CeLs further improved these and also increased water use efficiency (WUE). CeLn, CaLs, and CeLs significantly increased single fruit weight by 16.2%, 28.9%, and 36.6%, and yield per plant by 19.0%, 35.6%, and 60.8%, respectively. The effect of supplementary light on these parameters was superior to that of CO2 enrichment. In addition, CaLs and CeLs improved nutritional quality significantly. Taken together, CeLs promoted the greatest yield, WUE, and fruit quality, suggesting it may be a worthwhile practice for off-season tomato cultivation.

“…In another experiment, the application of supplementary lighting alone increased net photosynthesis and water use efficiency and these led to increased fruit yield and quality of pepper, though the combination of supplementary lighting and CO 2 improved these parameters better than supplementary lighting [18]. Naing et al also reported that the application of supplementary lighting alone or in combination with CO 2 significantly improved plant growth through increased plant height, stem diameter, and number of axillary shoots, as well as flower stem diameter, fresh weight, and number of petals per flower in rose plants under greenhouse conditions [19].In the northwestern part of China, the Chinese Solar Greenhouse (CSG) is widely utilized for vegetable cultivation during the winter period. The natural light available to the plants during the peak of winter is usually for a short period of about 7 h. To improve the growth of plants under the CSG, the application of supplementary light could be an option.…”

Red and blue light have great effects on physiological processes and growth of plants. In this experiment, we investigated the physiological and growth response of pepper (Capsicum annuum L.) to supplementary red:blue (4:1) light for 1 h (T1), 3 h (T2), and 5 h (T3), and the full-spectrum light-emitting diodes, LEDs, as control (CK). Thirty-day-old seedlings were grown under these treatments for 20 days in a climate-controlled room before data measurement. The results showed that the light treatments significantly (p < 0.05) affected the photosynthesis and growth indexes as well as gene expression in the pepper seedlings. Plants under T2 generally had better performance in terms of seedling growth. A total of 124, 1283, and 1091 differentially expressed genes were found in CK vs. T1, CK vs. T2, and CK vs. T3, respectively. Among the treatments, T2 in comparison with CK had 705 upregulated and 578 downregulated differentially expressed genes (DEGs). We also found that CPRF2, Paggis, HLIPS, GIGANTEA, LSH1, and FTSH genes were expressed differently under the various light treatments. Based on GeneOntology (GO) enrichment analysis, DEGs were significantly enriched on 15 GO terms of which xyloglucan:xyloglucosyl transferase activity and apoplastic, cellular polysaccharide metabolic, and cellular carbohydrate metabolic processes were closely related to light responses. A total of 96 genes that are related to plant-pathogen interaction, zeatin biosynthesis, plant hormone signal transduction, and wax/cutin/suberine biosynthesis which are involved in the pathway of light reaction in plants were significantly enriched in T2 plants compared with plants under CK. The application of red:blue light at 4:1 for 3 h improved the growth of pepper seedlings better than the other treatments and this can be tested under the Chinese Solar Greenhouse condition.The exposure of 'Green Oak Leaf' lettuce plants to fluorescent lamps with blue or red LEDs increased stem diameter, leaf area, leaf number, and dry biomass of shoot [5]. Brown et al. indicated that red LEDs in combination with other wavelengths of light may be suitable for the culture of plants under climate-controlled environments [6]. The application of red and blue light also affected biomass accumulation, pigment synthesis, antioxidants, and phenolic compounds. Moreover, chlorophyll contents increased significantly with increasing blue light in tomato, cucumber, radish, and pepper as compared with control plants [7]. Košvancová-Zitová et al. reported that irradiance with high B:R ratio (3:1) increased the rate of photosynthesis in Fagus sylvatica better than irradiance with low B:R (1:3) ratio [8]. In another experiment, Son et al. reported that the total antioxidant phenolic concentrations of lettuce plants increased as the proportion of blue light was increased [9]. Furthermore, different proportions of red and blue light have different effects on plant growth. A study showed that photosynthesis and yield of plants treated with LED-A (R:B = 6:3) were improved as compared to...

“…The combination of increased CO 2 and increased light intensity can promote dry matter accumulation and carbon assimilation (Proietti et al , Naing et al , Li et al , Lanoue et al ). These effects may be due to a synergistic effect on Pn to produce more carbohydrates – but this needs further investigation.…”

Carbon dioxide concentration (CO2) and light intensity are known to play important roles in plant growth and carbon assimilation. Nevertheless, the underlying physiological mechanisms have not yet been fully explored. Tomato seedlings (Solanum lycopersicum Mill. cv. Jingpeng No. 1) were exposed to two levels of CO2 and three levels of light intensity and the effects on growth, leaf gas exchange and water use efficiency were investigated. Elevated CO2 and increased light intensity promoted growth, dry matter accumulation and pigment concentration and together the seedling health index. Elevated CO2 had no significant effect on leaf nitrogen content but did significantly upregulate Calvin cycle enzyme activity. Increased CO2 and light intensity promoted photosynthesis, both on a leaf‐area basis and on a chlorophyll basis. Increased CO2 also increased light‐saturated maximum photosynthetic rate, apparent quantum efficiency and carboxylation efficiency and, together with increased light intensity, it raised photosynthetic capacity. However, increased CO2 reduced transpiration and water consumption across different levels of light intensity, thus significantly increasing both leaf‐level and plant‐level water use efficiency. Among the range of treatments imposed, the combination of increased CO2 (800 µmol CO2 mol−1) and high light intensity (400 µmol m−2 s−1) resulted in optimal growth and carbon assimilation. We conclude that the combination of increased CO2 and increased light intensity worked synergistically to promote growth, photosynthetic capacity and water use efficiency by upregulation of pigment concentration, Calvin cycle enzyme activity, light energy use and CO2 fixation. Increased CO2 also lowered transpiration and hence water usage.
