Abstract: Resumo -O objetivo deste trabalho foi avaliar o efeito de diferentes comprimentos de onda no desenvolvimento in vitro de mudas de cana-de-açúcar. Explantes foram submetidos a quatro tratamentos de diodos emissores de luz (LED): 100% azul; 70% azul + 30% vermelha; 30% azul + 70% vermelha; 100% vermelha, além do controle com lâmpada fluorescente branca. As plântulas foram avaliadas quanto a: número de brotações; altura; massa de matéria fresca e seca; e conteúdo de carotenoides e das clorofilas a e b. Observou-s… Show more

“…This behavior also occurred in FL and indicated that maximum and minimum light intensity applied (B:R=70:30 and FL, respectively) failed to benefit the synthesis of pigments. The highest Chl-a content in sugarcane variety CTC-07 was produced under 100% blue LED light (Maluta et al, 2013). However, the chlorophyll content of in vitro plantlets grown under different light qualities may be correlated with species or cultivars (Li et al, 2013).…”

“…As observed in the variety CTC-07, the highest rates were obtained when sugarcane plantlets were cultivated under FL. The effects of LED light in growth, morphology and tillering have been studied in several sugarcane varieties (Maluta, Bordignon, Rossi, Ambrosano, & Rodrigues, 2013;Rocha et al, 2013;Silva et al, 2014), suggesting that LEDs are an interesting light source for micropropagation. However, results suggest that the role of spectral light quality in controlling in vitro morphogenesis is not yet fully understood and may differ according to species and/or cultivars.…”

“…The results highlight the characteristic of the LEDs of having specific wavelength (Yeh & Chung, 2009), which differentiates them from other sources of light. LEDs are suitable for light supplementation because of their versatility and ease to combine wavelengths (Maluta et al, 2013). Souza et al (2011) state that, in addition to the intensity, the quality of the radiation is determinant for the development of the plant cells.…”

“…Resultados para Anthurium andraeanum (antúrio) indicaram o favorecimento da matéria fresca e seca na combinação de luz vermelha + azul, seguido pela luz branca (GU et al, 2012). Resultados similares também foram observados para a massa fresca da parte aérea de Saccharum officinarum (cana) (MALUTA et al, 2013). No presente estudo, a luz branca vermelha e a amarela incrementaram em maior quantidade de massa fresca da raiz e parte aérea.…”

“…Esse padrão foi verificado em abacaxi onde a luz vermelha foi mais eficiente que a luz branca no incremento de matéria seca de plântulas de abacaxi pertencente às cultivares Vitória e IAC fantástico (COUTO et al, 2014). In vitro grande parte dos trabalhos demonstraram que a luz vermelha + azul tem um papel no ganho de massa tanto da raiz como da parte área (GU et al,2012;MALUTA et al, 2013).…”
