Seedling production of bromeliad endemic to the semiarid region of Bahia, Brazil

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.

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