Micropropagation and in vitro conservation of Neoglaziovia variegata (Arr. Cam.) mez, a fiber producing bromeliad from Brazil
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...

| description | 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.<br>Neoglaziovia variegata é uma Bromeliaceae nativa da Caatinga, usada para extração de fibras na Região Nordeste do Brasil. A atividade antrópica coloca esta espécie entre as ameaçadas. O objetivo deste trabalho foi estabelecer uma propagação e conservação in vitro de caroá. Foram cultivadas sementes em meio MS na presença ou ausência de luz. Plântulas germinadas in vitro foram multiplicadas em meio MS suplementado com as combinações de 0,05 e 0.50 µM de NAA e 2.2 e 4.4 µM de BAP e KIN. Foram obtidas as melhores porcentagens de germinação com sementes incubadas na presença de luz. A taxa de multiplicação mais alta foi obtida no tratamento NAA (0,5 µM) + BAP (4,4 µM) e, o número de raízes, com NAA (0.5 µM) + KIN (2.2 µM). Aclimatização das plantas apresentou resultados diferenciados em relação aos substratos testados. A conservação foi estabelecida. |
