There is a large number of species within the genus Astrocaryum with the potential for use as food and for oil production. The most used species, tucumã do Amazonas, is consumed on a large scale in the States in the northern region of Brazil, originating from extractivism. Zygotic embryos of mature and immature tucumã do Amazonas (Astrocaryum aculeatum G. Mey.) seeds were inoculated in a semi-solid Murashige and Skoog (MS) culture medium supplemented with vitamins. The surviving embryos were transferred to the same MS medium supplemented with 0.0; 1.0; 3.0 and 5.0mg L-1 of BAP, obtaining an increasing rate of shoot formation.
