“…However, in in vitro propagation of Alpinia cultivars, exposure to white LED for Red Ginger cultivar provided a higher number of sprouts (Pinheiro et al, 2019). This variation in the formation of sprouts between species and cultivars was also reported in the in vitro banana crop, where Rocha et al (2017) evaluated the use of fluorescent lights and LEDs and demonstrated that the use of LED helps sprout development with variations between cultivars.…”

Light quality is an important factor for the adequacy of plant production through plant tissue culture, as it directly interferes with morphogenesis and photosynthetic capacity of explants. The objective of this study was to analyze the impact of monochromatic lights such as light emitting diode (LED) on the in vitro development of Cattleya walkeriana G. and their effects on acclimatization. The plants were developed in vitro under the colors of green, blue, yellow, red, 2 red:1 blue, and white LED lights. For in vitro cultivation, Knudson medium was used, supplemented with 20 mg L-1 sucrose, 5.5 mg L-1 agar, 2% activated charcoal, 100 mL coconut water, and pH 6.0. For ex vitro cultivation, the plants were acclimatized in styrofoam trays containing sphagnum as a substrate. In general, the supplied light lengths impactedin vitro growth and acclimatization analyses. There was influence on the cuticle thickness of plants in vitro. Chlorophyll and carotenoid contents were not significant. We can conclude that light lengths formed by 2 red:1 blue, red and yellow LEDs can be indicated for better performance in the production of C. walkeriana. The 2 red:1 blue and red LEDs provide superior in vitro development than the others, with gains for the species in acclimatization. The yellow LED provided a possible in vitro hardening, which ensured the greatest success of the seedlings during acclimatization.

“…For cultivar, regardless of the light source, Red Ginger was superior to Pink Ginger (Figure 1A). Rocha et al (2017), working with three banana cultivars, observed that the "Grande Naine" presented 2.6 shoots, with differences of almost a shoot when compared to the other cultivars. The same authors also reinforce that the LEDs can exert positive effects in the increase of the number of shoots, which can vary between the cultivars of the same species.…”

The light source in tissue culture is often one of the punctual factors for the adequacy of plant production. For this, light emitting diodes (LEDs) have been used in order to increase the growth and development of the plants propagated in vitro. The objective was to evaluate the in vitro propagation of cultivars of Alpinia purpurata ‘Red Ginger’ and ‘Pink Ginger’ in two different light sources (fluorescent or LEDs tubes). The experiment was conducted in a completely randomized design, factorial scheme (2x2), totaling four treatments with ten replicates, and the experimental unit composed of one flask containing five explants. After 55 days, white LED and the ‘Red Ginger’ provided the highest number of shoots. For the number of leaves, the cultivar ‘Red Ginger’ and white LED lamps provided superior results. For shoot length (cm), the cultivar ‘Red Ginger’ kept under fluorescent lamps was superior, and ‘Pink Ginger’ presented superiority when cultivated under LED lights. Thus, even with differentiated responses among genotypes, the use of white LED lamps in the in vitro propagation of Alpinia purpurata ‘Red Ginger’ and ‘Pink Ginger’ cultivars is suggested.

“…Os diodos emissores de luz (LEDs) são considerados uma opção bastante promissora, por apresentarem características importantes em relação às lâmpadas fluorescentes, que são convencionalmente usadas em laboratórios de micropropagação. Os LEDs possuem alta eficiência na geração de luz com baixa emissão de calor, podem ter sua intensidade e composição espectral controladas e, principalmente, são mais econômicos (Lazzarini et al, 2017;Rocha et al, 2017). Além disso, estudos mostraram que o uso de LEDs incrementa a taxa de multiplicação dos explantes e é capaz de proporcionar maior comprimento e número de brotações, devido à melhoria na qualidade de luz (Rocha et al, 2017).…”

Esse trabalho objetivou avaliar o efeito do tipo de luz no cultivo in vitro de Eugenia involucrata. Os tratamentos consistiram do cultivo sob diodos emissores de luz (LEDs) de cor vermelho, azul, verde ou branco e lâmpadas fluorescentes. Nos cultivos sob LEDs branco e azul foram observadas as maiores médias de estabelecimento; sob o azul e lâmpadas fluorescentes, o maior número de folhas; sob o azul, o maior número de brotos; sob o branco, menor contaminação bacteriana; e sob o verde os piores resultados. LEDs azul, vermelho, branco e lâmpadas fluorescentes influenciam favoravelmente a propagação in vitro de E. involucrata.
