Due to the multiple uses and extractive exploitation, this species has been threatened with extinction. Thus, it is important to develop strategies in order to ensure conservation and long term exploitation. This work aimed to establish a protocol of <em>in vitro</em> seed germination and micropropagation of <em>M. urundeuva</em>. Different support agents (vermiculite and agar) and presence of sucrose were tested for <em>in vitro</em> germination, while different concentrations of BAP (0.0, 0.5, 1.0 and 2.0 mg L<sup>-1</sup>) and explant types (apical and cotyledonary) were tested for multiplication. The use of vermiculite as a support agent favored <em>in vitro</em> germination of <em>M. urundeuva</em>, with germination percentage of 64.3% and 32% for vermiculite and agar, respectively. No significant differences were observed for the different BAP concentrations tested in multiplication and the treatment with 1.0 mg L<sup>-1</sup> BAP presented higher values for most variables analyzed. Cotyledonary explants presented higher number of shoots (1.6 shoots) compared to the apical ones (1.1 shoots). Vermiculite may be used as a replacement for agar for <em>in vitro</em> seed germination and the combination of 1.0 mg L<sup>-1</sup> of BAP and cotyledonary explants may be used for <em>in vitro </em>multiplication of <em>M. urundeuva</em>. Furthermore, studies are needed to improve <em>in vitro</em> multiplication methods of this species.</p>}, journal={Plant Cell Culture & Micropropagation - ISSN 1808-9909}, author={Vinicius de Souza Nascimento, Augusto and Mendonça, Ane Marcela das Chagas and da Silva Júnior, Carlos Dias and de Santana, Marlucia Cruz and Santos, Paulo Augusto Almeida}, year={2020}, month={Oct.}, pages={16:e156} }
