Conteúdo: | Neoglaziovia variegata (Arr. Cam.) Mez is a Bromeliaceae native to the Caatinga, used for fiber extraction in the Northeast Region of Brazil. The antropic activity has place this species among the threatened ones. The objective of the work was to establish an in vitro propagation and conservation of caroá. Seeds were cultivated in MS medium in the presence or absence of light. In vitro germinated seedlings were multiplied in MS medium supplemented with the combinations 0.05 and 0.50 µM NAA and 2.2 and 4.4 µM BAP and KIN. The best percentages of germination were obtained with the seeds incubated in the presence of light. The highest multiplication ratio was obtained for the NAA (0,5 µM) + BAP (4,4 µM) treatment and the number of roots, with NAA (0.5 µM) + KIN (2.2 µM). Plant acclimatization presented differentiated results regarding the substrates tested. The conservation was established.
