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. Invitro 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 exvitro condition, and 100% plant survival was obtained.
It is concluded, therefore, that the production of seedlings of N. mucugensis is viable by micropropagation.

Key words: activated charcoal, direct organogenesis, in vitro cultivation, Neoregelia mucugensis.


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.
