Title A name given to the resource Substratos no enraizamento de estacas herbáceas de amora-preta Xavante Substrates on rooting of blackberry Xavante herbaceous cuttings Creator An entity primarily responsible for making the resource Lilian Yukari Yamamoto, Renata Koyama, Wellington Fernando Silva Borges, Luís Eduardo Corrêa Antunes, Adriane Marinho de Assis, Sérgio Ruffo Roberto Description An account of the resource A amora-preta (Rubus spp.) destaca-se entre as espécies que apresentam boas perspectivas de cultivo em áreas de agricultura familiar. Visando a otimizar a multiplicação de mudas dessa espécie, o objetivo deste trabalho foi avaliar o uso de substratos e concentrações do ácido indolbutírico (AIB) no enraizamento de estacas de amora-preta Xavante. O delineamento experimental foi o inteiramente casualizado em arranjo fatorial 3x2 (três tipos de substratos e duas concentrações de AIB), com cinco repetições de sete estacas, sendo adotados os fatores: tipos de substratos (casca de arroz carbonizada, vermiculita grânulos médios e fibra de coco) e tratadas ou não com AIB (0 e 1000mg L-1). Após 80 dias, foram avaliadas as variáveis: sobrevivência das estacas; retenção foliar; estacas enraizadas; número de raízes por estaca; comprimento da maior raiz; massa seca das raízes por estaca; e pH; condutividade elétrica; densidade e capacidade de retenção de água dos substratos. Não houve influência dos substratos e da aplicação de AIB sobre a porcentagem de estacas enraizadas, verificando-se alta eficiência no enraizamento das estacas de amora-preta Xavante (86,2%). Para a porcentagem de sobrevivência das estacas, o melhor resultado foi obtido sem a aplicação de AIB. Conclui-se que a amora-preta Xavante pode ser propagada por estaquia herbácea com eficiência, sem o uso de AIB, utilizando-se preferencialmente o substrato casca de arroz carbonizada como opção de baixo custo.The blackberry (Rubus spp.) stands out among the species that have good prospects for cultivation in areas of family farm agriculture. In order to optimize the multiplication of seedlings of this species, the aim of this research was to evaluate the use of different substrates and concentrations of indolebutyric acid (IBA) on the rooting of cuttings of blackberry Xavante. The experiment was performed using the completely randomized design in a 3x2 factorial arrangement (three substrates and two concentrations of IBA), with five replications of seven cuttings, and the following factors were adopted: types of substrates (vermiculite medium granules, carbonized rice husk and coconut fiber) and treated or not treated with IBA (0 and 1000mg L-1). After 80 days, the following variables were evaluated: cuttings survival; leaf retention; rooted cuttings; root number per cutting; length of the longest root; dry weight of roots per cutting; and pH; electrical conductivity; bulk density and water retention capacity of the substrates. There was no influence of the substrates and the IBA on the percentage of rooted cuttings, verifying the high efficiency on rooting of the blackberry Xavante cuttings (86.2%). For the percentage of cuttings survival the best result was obtained without the IBA application. It was concluded that the blackberry Xavante can be propagated by herbaceous cuttings efficiently, using the carbonized rice husk as low-cost option.
