Somatic embryogenesis from zygotic embryos of Euterpe oleracea Mart.
The aim of this work was to study the morphogenetic responses of zygotic embryos of açai palm (Euterpe oleracea Mart.) submitted to several conditions of in vitro culture. Several research experiments were conducted, in laboratory, using vegetable material collected from açai palm plants at Embrapa Amazon Oriental, Belém-PA, Brazil. It was possible to verify the expression of a direct, repetitive and no-synchronized model of somatic embryogenesis in mature zygotic embryos cultivated in primary MS medium supplemented with 2,4-D (339.36 muM) and transferred to a secondary MS medium in the presence of NAA (0.537 muM) and 2iP (12.30 muM). The conversion of somatic embryos into seedlings was reached after 210 days with the transfer of the cultures to a third medium with sucrose and mineral salts concentrations reduced to a half, without growth regulators.
