- IN VITRO DEVELOPMENT AND ACCLIMATIZATION OF DENDEZEIRO (Elaeis guineensis) Marlúcia Souza Souza Pádua Luciano Viela Paiva Luis Gustavo Texeira da Silva Luciano Coutinho Silva Vanessa Cristina Stein Agrociencias Germination Carbohydrates Growth regulators Fruits and almond from the dendezeiro, oil palmbelonging to the Elaeis genus,are widely used for the production of cookingoils or for the pharmaceutical and cosmetic industries.In the last decade, this oil palm also emerged as a promising source for commercialbiofuel production. This study evaluated the effect of different culture media, MS (MURASHIGUE AND SKOOG) and Y3 (EEUWENS)and carbohydrates duringin vitro germination of zygotic embryos, the effect of growth regulators GA3, NAA and BA Ponin vitro seedling development, and the survival rate of acclimatized seedlingsof Manicoré hybrid (Elaeis oleifera x E. guineensis). Zygotic embryos were inoculated on MS and modified Y3 media, supplemented with different sucrose concentrations (30, 45, and 60 gL-1) or sorbitol (36 gL-1), and the germination rate was evaluated after 30 days. Subsequently, seedlings were transferred to modified Y3 culture medium supplemented with differentGA3 concentrations (3.5 and 7 mgL-1) or without it, combined or not with 1 mgL-1 of NAA, 5 mgL-1 of BAP.The highest germinationpercentage of germinated embryos (92%) was observed in MS medium supplemented with 36 gL-1 sorbitol. Culture media supplemented with growth regulatorsGA3, NAA and BAP promoted greater shoot lengththan control media. Rooted seedlings showed high survival percentage (85%) during acclimatization. 2014 artículo científico 0100-6762 https://www.redalyc.org/articulo.oa?id=48837807014 en http://www.redalyc.org/revista.oa?id=488 Revista Árvore application/pdf Universidade Federal de Viçosa Revista Árvore (Brasil) Num.6 Vol.38
