“…Similar results, showing the positive influence of the combined use of red and blue light on maximum quantum yield of PSII, compared to solely blue or red, have been described for some horticultural plants such as Dendrobium officinale [41], Lactuca sativa [42], Solanum lycopersicum [19], and Campomanesia pubescens [43], as well as Cordyline australis, Ficus benjamina, and Sinningia speciosa [44]. At the same time, other authors indicated that monochromatic red light reduced the photosynthetic efficiency, and led to photo-damage after long-term exposure [9,43,44]. In another study, Fv/FM for Houttuynia cordata seedlings was the highest under blue LED light, and the lowest under green LED light [45].…”

We investigated the growth traits, flower bud formation, photosynthetic performance, and powdery mildew development in miniature Rosa × hybrida ‘Aga’ plants grown in the greenhouse under different light-emitting diode (LED) light spectra. Fluorescence-based sensors that detect the maximum photochemical efficiency of photosystem II (PS II) as well as chlorophyll and flavonol indices were used in this study. Five different LED light treatments as a supplement to natural sunlight with red (R), blue (B), white (W), RBW+FR (far-red) (high R:FR), and RBW+FR (low R:FR) were used. Control plants were illuminated only by natural sunlight. Plants were grown under different spectra of LED lighting and the same photosynthetic photon flux density (PPFD) (200 µmol m−2 s−1) at a photoperiod of 18 h. Plants grown under both RBW+FR lights were the highest, and had the greatest total shoot length, irrespective of R:FR. These plants also showed the highest maximum quantum yield of PS II (average 0.805) among the light treatments. Red monochromatic light and RBW+FR at high R:FR stimulated flower bud formation. Moreover, plants grown under red LEDs were more resistant to Podosphaera pannosa than those grown under other light treatments. The increased flavonol index in plants exposed to monochromatic blue light, compared to the W and control plants, did not inhibit powdery mildew development.

“…In red LED there was damage to the membranes of thylakoids, increasing the MDA value and reducing the content of photosynthetic pigments (chlorophyll b and carotenoids). However, the importance of further research on the effects of light quality and different intensities is emphasized, as well as examining these effects on the concentration of compounds such as terpenes (Centofante, et al, 2020).…”

Campomanesia pubescens (gabiroba) is a fruit tree that is native to the Cerrado and that has commercial potential and medicinal properties. It has recalcitrant seeds that do not tolerate desiccation and storage. Here, C. pubescens plants were grown in vitro under different light qualities. Light-emitting diodes (LEDs) were used at wavelengths for white (W) and blue in combination with red in the proportions BR (1:1), BR (1:3) and BR (3:1), at 100 ± 5 μmol m-2 s-1 over a 16-hour photoperiod. The leaf anatomy, chlorophyll a fluorescence, chloroplast pigments and malondialdehyde (MDA) content were evaluated. Studies on Cerrado plants grown in vitro focusing on light quality and its effects on plant development and growth are scarce. Records of anatomical and physiological C. pubescens characteristics when grown in vitro under different lighting qualities using LEDs are nonexistent. In this context, the aim of this study was to analyze the anatomical and physiological responses of C. pubescens seedlings from in vitro cultivation under different light qualities, to support future studies on the propagation and conservation of this species. This work is a pioneer for this species. When the plants were cultivated in combinations of blue/red LEDs 1:1 and 3:1, they yielded higher biomass, presenting higher epidermis and chlorenchyma values with greater stomatal density and functionality, better photosynthetic efficiency, higher Y(II) values, qP and higher total chlorophyll concentrations, and thus these lights did not cause oxidative damage compared to the white (control) LEDs. This study contributed to a better understanding of the anatomical and physiological changes in C. pubescens plants grown in vitro under different light qualities. C. pubescens plants exhibited varied anatomical and physiological characteristics depending on the spectrum of light used here. The combinations of BR (1:1) or BR (3:1) LEDs are promising for the propagation of the species, given their positive influence on most of the studied traits.

“…Researches on LED light quality was focused on crops in earlier stage ( Zheng et al., 2019b ; Goins et al., 1997 ), but have been switched to fruits, vegetables, flowers, etc. recently, such as pomegranates ( Bantis et al., 2018 ), gabirobas ( Centofante, 2019 ), hydroponic lettuces ( Yan et al., 2019 ), and phalaenopsis ( Ren et al., 2016 ), which are of higher economic value.…”

Brasenia schreberi J. F. Gmel, a perennial floating-leaved macrophyte with high economic value as an aquatic vegetable, has been listed as first-class endangered species in China, mainly due to its habitat loss. Protected cultivation is a potential strategy to meet the demand of both plant conservation and vegetable market, whereas pre-experiments are still needed before series of parameters can be properly set for the large-scale growth of the plants indoor. Light quality is one of the major factors controlling the development of plants and consequently becomes an important factor when planting B. schreberi indoor. This experiment used three artificial light sources to investigate the response of B. schreberi seedlings to different light qualities, including the red-blue LED light (red: blue = 5:1, RB-LED), the white LED light (W-LED) and the white fluorescent (W-Fluo). Our results indicated that the responses of B. schreberi towards varied light qualities differed from those of most terrestrial plants. The total leaf number of the RB-LED treatment was the highest; the number of the submerged leaf and the rolled leaf of the RB-LED treatment was higher than that of the other two treatments, but the number of floating leaves was the lowest. Both the specific leaf weight and the pigment contents per unit leaf area were the lowest in the RB-LED treatment. Quantum yield of PSⅡ ( Φ PSⅡ ), electron transport rate (ETR) and photochemical quenching ( q P) measured through light induction curves followed the sequence from high to low as W-Fluo > W-LED > RB-LED, whereas the trend of non-photochemical quenching (NPQ) reversed. The maximum potential ETR ( P s ) and maximum ETR (ETR m ) derived from ETR curves further verified the trends.
