Description
Summary:Abstract Bromeliads are plants that, in addition to marked ecological importance, have increasing ornamental potential in the flower market, being commonly collected in an extractive way, which results in genetic loss of the exploited species, putting them in different degrees of threat. Culture of plant tissues has been shown to be a viable alternative for the propagation of many bromeliads. The aim of this study was to produce seedlings of Neoregelia mucugensis by micropropagation. In vitro multiplication of sprouts via direct organogenesis was obtained in static liquid medium containing 6-benzylaminopurine (BAP) cytokinin. The sprouts were rooted in activated charcoal medium and transferred to the ex vitro condition, and 100% plant survival was obtained. It is concluded, therefore, that the production of seedlings of N. mucugensis is viable by micropropagation. Resumo As bromélias são plantas que além de acentuada importância ecológica, apresentam crescente potencial ornamental no mercado de flores, sendo comumente coletadas de forma extrativista, o que acarreta perda genética das espécies exploradas, pondo-as em diferentes graus de ameaça. A cultura de tecidos vegetais tem se mostrado uma alternativa viável para a propagação de muitas bromeliáceas. O objetivo deste estudo foi produzir mudas de Neoregelia mucugensis por micropropagação. A multiplicação de brotos via organogênese direta foi obtida em meio líquido estático contendo a citocinina 6-benzilaminopurina (BAP). Os brotos foram enraizados, em meio com carvão ativado, e transferidos para a condição ex vitro, sendo obtidos 100% de sobrevivência das plantas. Conclui-se, portanto que a produção de mudas de N. mucugensis é viável por micropropagação.
