“…Therefore, the optimum growth light intensity for light use efficiency was clearly the 300 µmol m −2 s −1 PPFD. In lettuce, the optimum growth light intensity was 600 µmol m −2 s −1 PPFD 16,17,[41][42][43][44] , while for Aloe vera L. it was 50% of sunlight as compared to 75 or 100% 44 . F v /F m was generally not affected by TiO 2 nanoparticle spray, except for an increase noted at 75 µmol m −2 s −1 PPFD.…”

Due to the photocatalytic property of titanium dioxide (TiO2), its application may be dependent on the growing light environment. In this study, radish plants were cultivated under four light intensities (75, 150, 300, and 600 μmol m−2 s−1 photosynthetic photon flux density, PPFD), and were weekly sprayed (three times in total) with TiO2 nanoparticles at different concentrations (0, 50, and 100 μmol L−1). Based on the obtained results, plants used two contrasting strategies depending on the growing PPFD. In the first strategy, as a result of exposure to high PPFD, plants limited their leaf area and send the biomass towards the underground parts to limit light-absorbing surface area, which was confirmed by thicker leaves (lower specific leaf area). TiO2 further improved the allocation of biomass to the underground parts when plants were exposed to higher PPFDs. In the second strategy, plants dissipated the absorbed light energy into the heat (NPQ) to protect the photosynthetic apparatus from high energy input due to carbohydrate and carotenoid accumulation as a result of exposure to higher PPFDs or TiO2 concentrations. TiO2 nanoparticle application up-regulated photosynthetic functionality under low, while down-regulated it under high PPFD. The best light use efficiency was noted at 300 m−2 s−1 PPFD, while TiO2 nanoparticle spray stimulated light use efficiency at 75 m−2 s−1 PPFD. In conclusion, TiO2 nanoparticle spray promotes plant growth and productivity, and this response is magnified as cultivation light intensity becomes limited.

“…In contrast, R light partitioned more biomass into the root and caused the highest root dry weight to be gained when the biomass of both monochromatic light recipes is compared to the biomass of plants exposed to other light qualities ( Figure 1 and Table 1 ). The alteration of biomass partitioning to different plant organs as a consequence of plant growth in different lighting environments has been reported in diverse plant species such as chrysanthemum [ 30 ], saffron [ 28 , 31 ], bromeliads [ 32 ], and lettuce [ 23 , 33 ].…”

Chrysanthemum (Chrysanthemum morifolium) is among the most popular ornamental plants, propagated mainly through stem cuttings. There is a lack of information regarding the impact of the lighting environment on the successful production of cuttings and underlying mechanisms. The light spectrum affects plant morphology, growth, and photosynthesis. In the present study, chrysanthemum, cv. ‘Katinka’ cuttings, were exposed to five lighting spectra, including monochromatic red (R), blue (B) lights, and multichromatic lights, including a combination of R and B (R:B), a combination of R, B, and far red (R:B:FR) and white (W), for 30 days. B light enhanced areal growth, as indicated by a higher shoot mass ratio, while R light directed the biomass towards the underground parts of the cuttings. Monochromatic R and B lights promoted the emergence of new leaves. In contrast, individual leaf area was largest under multichromatic lights. Exposing the cuttings to R light led to the accumulation of carbohydrates in the leaves. Cuttings exposed to multichromatic lights showed higher chlorophyll content than monochromatic R- and B-exposed cuttings. Conversely, carotenoid and anthocyanin contents were the highest in monochromatic R- and B-exposed plants. B-exposed cuttings showed higher photosynthetic performance, exhibited by the highest performance index on the basis of light absorption, and maximal quantum yield of PSII efficiency. Although R light increased biomass toward roots, B light improved above-ground growth, photosynthetic functionality, and the visual performance of Chrysanthemum cuttings.

“…The combination of R and B light is an e cient light source for crop production in CEA (27). In the previous studies, the importance of using R and B light spectra on the photosynthesis and growth of horticultural crops is highlighted (10). R light promotes plant growth and root development (24).…”

During the seasons with limited light intensity, reductions in growth, yield and quality are challenging issues for commercial cut rose production in greenhouses. Using artificial supplemental light is recommended for maintaining commercial production in regions with limited light intensity. Nowadays, replacement of traditional lighting sources with LEDs attracted lots of attentions. Since red (R) and blue (B) light spectra present the important wavelengths for the photosynthesis and growth, in the present study different ratios of supplemental R and B lights including 90% R: B 10% (R90B10), 80% R: 20% B (R80B20), 70% R: 30% B (R70B30) with an intensity of 150 µmol m− 2 s− 1 together with natural light and without supplemental light (control) were applied on two commercial rose cultivars. According to the obtained results, supplemental light improved growth, carbohydrate levels, photosynthesis capacity, and yield when compared to the control. R90B10 in both cultivars reduced the time required for flowering compared to the control treatment. The highest number of harvested flower stems was obtained by R90B10 and R80B20 in both cultivars. Chlorophyll and carotenoid levels were the highest under control and higher ratio of B light, while carbohydrate and anthocyanin contents increased by having high ratio of R light in the supplemental light. Analysis of chlorophyll fluorescence were indicative of better photosynthetic performance under high ratio of R light in the supplemental light. In conclusion, R90B10 light regime is recommended as suitable supplemental light recipie to improve growth and photosynthesis, to accelerate flowering, and to improve the yield and quality of cut roses.
