Resumo: The objective of this work was to evaluate the effect of six indole-3-acetic acid (IAA) concentrations and three immersion times in IAA solutions on the vegetative propagation of Spondias dulcis and Spondias tuberosa by stem cuttings. The experiment was conducted in a greenhouse, using a completely randomized design, with a 6×3 factorial arrangement consisting of six indole-3-acetic acid concentrations (0, 2, 4, 6, 8, and 10 g L-1) and three immersion times (8, 16, and 24 seconds), with ten cuttings of S. dulcis and S. tuberosa per plot, and three replications. Percentage of surviving cuttings, and percentage of rooted cuttings, number of leaf buds, number of roots per cutting, root length, and total fresh weight were evaluated at 180 days after planting. Data were subjected to analysis of variance by the F test and to regression analysis. Vegetative propagation from woody cuttings of S. dulcis is not viable to produce seedlings, thus, new studies on this technique for this species are needed. Vegetative propagation from woody cuttings of S. tuberosa is satisfactory, but with low efficiency for improvement and emergence of new shoots and roots; it is more effective when using a concentration of 10 g L-1 of indole-3-acetic acid and immersion time in the solution of 16 seconds.

O experimento foi conduzido em delineamento experimental inteiramente causalizados, em esquema fatorial (6 x 3), em seis concentrações (0, 2, 4, 6, 8 e 10 g L-1) do AIA e três intervalos de imersão (8, 16 e 24 segundos), com dez estacas por parcela de S. dulcis e S. tuberosa, com três repetições, em casa de vegetação. A porcentagem de sobrevivência das estacas, porcentagem de estacas enraizadas, número de brotações jovens foliares, número de raízes por estacas, comprimento geral das raízes e massa fresca total foram avaliadas aos 180 dias após o plantio. Os dados foram submetidos à análise de variância pelo teste de F e ajustados em equações de regressão. Concluiu-se que a propagação vegetativa na espécie Spondias dulcis não obteve resultados satisfatórios utilizando a técnica proposta no trabalho. Concluiu-se, também, que a técnica de propagação vegetativa na espécie Spondias tuberosa obteve resultados satisfatórios, porém, com pouca eficiência para o aumento e emergência de novos brotos e raízes, e mais efetiva na concentração 10 g L-1 de AIA, com 16 segundos de imersão.Universidade Federal Rural do Semi-Árido2019-11-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/765410.1590/1983-21252019v32n401rcREVISTA CAATINGA; Vol. 32 No. 4 (2019); 858-866Revista Caatinga; v. 32 n. 4 (2019); 858-8661983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/7654/10095Copyright (c) 2019 Revista Caatingainfo:eu-repo/semantics/openAccessRocha, Gabriela TeodoroSilva, Ayure Gomes daMartins, Juliana BezerraPeixoto, NeiRodrigues, Fabricio2023-07-20T17:50:00Zoai:ojs.periodicos.ufersa.edu.br:article/7654Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:36.202973Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
