Resumo: The importance of eucalypts species and their interspecific hybrids has been evidenced in forestry programmes due to their wood quality and adaptation to diverse environmental conditions. To solve the limiting factors in the in vitro cultivation of the A211 clone of Eucalyptus grandis Hill ex Maiden × Eucalyptus urophylla S. T. Blake, the aim of the study was to evaluate the light quality on in vitro establishment, multiplication, elongation and rooting stages. The tissues used to obtain explants were nodal segments derived from ministumps of the A211 clone. The effects of light quality on in vitro establishment, multiplication, elongation and rooting were evaluated using five sources (fluorescent lamp, white LEDs, red LEDs, blue LEDs and red/blue LEDs). At 30 days, the percentage of contamination and non-responsive explants, length and number of shoots per explant, oxidation, shoot vigor, pigment content, leaf anatomy, root length and number of roots per explant were evaluated. Fluorescent lamps and red/blue LEDs are more suitable for use in the in vitro establishment, multiplication, elongation and rooting of the A211 clone, without hindering the development of shoots for the production of micropropagated clonal plants.

Para solucionar os fatores limitantes ao cultivo in vitro do clone A211 de Eucalyptus grandis Hill ex Maiden × Eucalyptus urophylla S. T. Blake, o presente trabalho teve como objetivo avaliar a influência da qualidade de luz nas fases de introdução, multiplicação, alongamento e enraizamento in vitro. Os tecidos utilizados para a obtenção dos explantes foram segmentos nodais, provenientes de minicepas do clone A211 de E. grandis × E. urophylla. Os efeitos no cultivo in vitro foram avaliados por meio de cinco fontes de qualidade de luz (Lâmpada fluorescente, LEDs branco, LEDs vermelho, LEDs azul e LEDs vermelho/azul). Dados de porcentagem de contaminação e explantes não responsivos, comprimento e número de brotos por explante, oxidação, vigor das brotações, conteúdo de pigmentos, anatomia foliar, comprimento e número de raízes por explante foram coletados aos 30 dias de cultivo in vitro. Com base nos resultados obtidos, pôde-se inferir que as lâmpadas fluorescentes e LEDs vermelho/azul são as mais adequadas para serem utilizadas na introdução, multiplicação, alongamento e enraizamento in vitro do clone A211 de E. grandis × E. urophylla, não ocasionando prejuízos no desenvolvimento de brotações destinadas à produção de plantas clonais micropropagadas.Instituto de Pesquisas e Estudos Florestais - IPEF2021-08-20T19:02:54Z2021-08-20T19:02:54Z2020-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSOUZA, D.
