________________________________________________________________________________ ResumoObjetivando avaliar a viabilidade do método de propagação por estaquia no tamarindeiro foram utilizadas estacas folhosas apicais e basais, sendo tratadas com dois tipos de auxinas, ácido indolbutírico (AIB) e ácido naftalenoacético (ANA) nas concentrações de 0, 1000, 3000, 5000 e 7000mg.L -1 . As estacas foram com fungicida por 5mim e receberam adubo foliar contendo NPK e Boro de 15 em 15 dias. Como substrato, foram utilizados a mistura de vermiculita média, areia fina e palha de arroz, acondicionadas por 90 dias no leito de enraizamento com nebulização intermitente. Dentre os resultados obtidos á melhor concentração para a porcentagem de enraizamento, porcentagem de sobrevivência, número médio de raízes e comprimento médio de raízes foi na concentração de 5000mg.L -1 para AIB e ANA. O método de propagação do tamarindeiro pelo método de estaquia não é viável.

AbstratThe objective of this study was to evaluate the viability of the cutting method in the tamarind tree, using apical and basal hardwood cuttings, with two types of auxins, indolebutyric acid (AIB) and naphthaleneacetic acid (ANA) at concentrations of 0, 1000, 3000, 5000 and 7000mg.L-1. The cuttings were with fungicide for 5 mm and received leaf fertilizer containing NPK and Boron every 15 days. As substrate, a mixture of medium vermiculite, fine sand and rice straw was used, conditioned for 90 days in the rooting bed with intermittent misting. Among the results obtained at the best concentration for rooting percentage, survival percentage, mean number of roots and mean root length was 5000 mg.L -1 for AIB and ANA. The method of propagation of the tamarind seed by the cutting method is not feasible.
