چکیده

A intensificação da exploração seletiva de madeiras tem ocasionado grandes perdas na biodiversidade espécies nativas alto valor econômico, comprometendo, a sua sobrevivência. O potencial madeireiro do mogno brasileiro é mundialmente reconhecido e, por isso, também motivo grande preocupação comunidade científico. Esta pesquisa objetiva avaliar o efeito concentrações reguladores crescimento germinação e multiplicação in vitro analisar aspectos físicos para determinar eficiência produção mudas. Para as sementes foram incubadas em meio cultura MS no delineamento inteiramente casualisado esquema fatorial 2 x 4 (duas intensidades luz quatro tempos hipoclorito sódio), com cinco repetições repetição. Aos trinta dias, os explantes isentos contaminação transferidos tubos ensaio contendo suplementados diferentes BAP mantidos sala crescimento. brotos ANA. Obtiveram-se maior porcentagem brotações (83%) porção intermediária utilização superiores ANA formação calos permitindo êxito clonal. Palavras-chave: espécie nativa; plantas lenhosas; micropropagação. Germination and propagation of brazilian mahogany (Swietenia macrophylla King) ABSTRACT: The intensification selective logging causes great losses biodiversity native species high economic value, compromising their survival. wood industry potential is recognized worldwide and, therefore, it also cause preoccupations the scientific community. This research aims to evaluate effect concentrations growth regulators on germination multiplication analyze physical aspects determining efficiency production seedlings. For this, seeds were incubated culture medium completely randomized design factorial scheme (two light intensities four sodium hypochlorite times) with five repetitions per supplemented different kept repetition. At thirty days, explants free from contamination transferred test tubes containing room. shoots highest number percentage use intermediate higher for callus formation enabling success clonal production. Keywords: species; woody plants; micropropagation.
