Resumo: O noni (Morinda citrifolia L.) é pertencente à família Rubiaceae, cresce extensivamente entre as ilhas do Pacífico, sendo considerada uma das mais significantes plantas da medicina tradicional dessas comunidades. Sua introdução se deu há poucos anos e, devido a isto, ainda não há material propagativo suficiente para o cultivo em escala comercial, porém, nas últimas décadas, observou-se um aumento significativo do interesse comercial em relação aos produtos contendo essa planta, principalmente o suco das frutas do noni. Objetivou-se avaliar diferentes substratos no enraizamento de estacas de noni. O experimento foi conduzido no viveiro de produção de mudas, no Instituto Federal do Espírito Santo. Foram utilizadas estacas de talão, colhidas em plantas adultas de noni com 20 cm de comprimento, e colocadas para enraizar em tubetes 290 mL, nos substratos: terra, areia, bioplant ® e vermiculita. O delineamento foi inteiramente casualizado, com cinco repetições de doze estacas, sendo avaliados após 120 dias as variáveis: sobrevivência das estacas; número de folhas; diâmetro do coleto; comprimento da raiz; volume de raízes; massa verde raiz; massa verde folhas; massa seca raiz e massa seca folhas. O substrato terra mostrou-se superior aos outros substratos, sendo recomendado o transplante precoce de estacas de noni enraizadas em tubetes.Palavras chave: Morinda citrifolia; Propagação vegetativa; Estaquia. Abstract:The noni (Morinda citrifolia L.) belongs to the Rubiaceae family, growing extensively among the Pacific islands, being considered one of the most significant traditional medicine plants of these communities. Its introduction occurred only a few years ago, and because of this, there is still not enough propagating material for cultivation on a commercial scale, but in the last decades there has been a significant increase in commercial interest in relation to the products containing this plant, mainly the juice of noni fruits. The objective of this study was to evaluate different substrates in the rooting of noni cuttings. The experiment was conducted at the seedling nursery at the Federal Institute of Espírito Santo. Beech cuttings were harvested in 20 cm long noni adult plants and placed in 290 mL tubing on substrates: soil, sand, bioplant ® and vermiculite. The design was completely randomized, with five replications of twelve stakes, being evaluated after 120 days the variables: survival of the stakes; number of leaves; collecting diameter; root length; volume of roots; root green mass; green leaves; dry mass root and dry mass leaves. The soil substrate showed to be superior to the other substrates, being recommended the early transplant of noni cuttings rooted in tubes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
