Resumo: This work aimed to analyze the micropropagation technique in two pitaya species under different concentrations of growth regulators and the effect of different substrates on the acclimatization of their seedlings. The research took place at the Plant Biotechnology Laboratory – BIOVEG – belonging to the Federal University of Alagoas – CECA/UFAL. Seeds of mature fruits of H. undatus and H. megalanthus from commercial plantations in the states of Pernambuco and Ceará, respectively, were used. Two pitaya species (H. undatus and H. megalanthus) and four concentrations of IBA, four concentrations of 6-benzylaminopurine plus the control (without IBA or BAP) were used. A rooting experiment with the same culture media used in the multiplication experiment, but using microcladodes with only the base part removed. The results showed that cytokinin BAP considerably stimulated the production of new shoots in both pitaya species when compared to the control. The species H. megalanthus presented number of sprouts and roots than the species H. undatus. The substrates Bioplant and cajá seed fiber presented results for length and number of roots, as well as for fresh and dry mass superior to vermiculite for the two studied species, being indicated for the production of pitaya seedlings. The purple pitaya variety was the one that always showed the best responses in shoots and roots, both in vitro and extra vitro.

La investigación tuvo lugar en el Laboratorio de Biotecnología Vegetal – BIOVEG – perteneciente a la Universidad Federal de Alagoas – CECA/UFAL. Se utilizaron semillas de frutos maduros de H. undatus y H. megalanthus de plantaciones comerciales en los estados de Pernambuco y Ceará, respectivamente. Se utilizaron dos especies de pitaya (H. undatus y H. megalanthus) y cuatro concentraciones de IBA, cuatro concentraciones de 6-bencilaminopurina más el control (sin IBA ni BAP). Un experimento de enraizamiento con los mismos medios de cultivo utilizados en el experimento de multiplicación, pero utilizando microcladodios con solo la parte de la base eliminada. Los resultados mostraron que la citoquinina BAP estimuló considerablemente la producción de nuevos brotes en ambas especies de pitaya en comparación con el control. La especie H. megalanthus presentó mayor número de brotes y raíces que la especie H. undatus. Los sustratos Bioplant y fibra de semilla de cajá presentaron resultados de longitud y número de raíces, así como de masa fresca y seca superiores a la vermiculita para las dos especies estudiadas, siendo indicados para la producción de plántulas de pitaya. La variedad pitaya morada fue la que siempre mostró mejores respuestas en brotes y raíces, tanto in vitro como extra vitro.Este trabalho objetivou analisar a técnica de micropropagação em duas espécies de pitaya sob diferentes concentrações de reguladores de crescimento e o efeito de diferentes substratos na aclimatização de suas plântulas. A pesquisa ocorreu no Laboratório de Biotecnologia Vegetal – BIOVEG - pertencente a Universidade Federal de Alagoas – CECA/UFAL. Foram utilizadas sementes de frutos maduros de H. undatus e H. megalanthus oriundos de plantios comerciais nos Estados de Pernambuco e Ceará, respectivamente. Foram utilizadas duas espécies de pitaya (H. undatus e H. megalanthus) e quatro concentrações de AIB, quatro concentrações de 6- benzilaminopurina mais o controle (sem AIB ou BAP). Um experimento de enraizamento com os mesmos meios de cultura utilizados no experimento de multiplicação, mas utilizando microcladódios com apenas a parte da base removida. Os resultados mostraram que a citocinina BAP estimulou consideravelmente a produção de novas brotações nas duas espécies de pitaya quando comparado ao controle. A espécie H. megalanthus apresentou número de brotações e raízes do que a espécie H. undatus. Os substratos Bioplant e fibra de caroço de cajá apresentaram resultados de comprimento e número de raízes, assim como para massa fresca e seca superiores à vermiculita para as duas espécies estudadas, sendo indicados para a produção de mudas de pitaya. A variedade de pitaya roxa foi a que apresentou sempre as melhores respostas em brotações e raízes, tanto na fase in vitro quanto na fase extra vitro.Research, Society and Development2022-12-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3875610.33448/rsd-v11i17.38756Research, Society and Development; Vol. 11 No. 17; e176111738756Research, Society and Development; Vol. 11 Núm. 17; e176111738756Research, Society and Development; v. 11 n. 17; e1761117387562525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/38756/32181Copyright (c) 2022 Terezinha Ramalho Neta; Dimas de Barros Santiago; Wellington Manoel dos Santos; José Dailson Silva de Oliveira; Cibele Merched Gallo; Eurico Eduardo Pinto de Lemoshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRamalho Neta, TerezinhaSantiago, Dimas de Barros Santos, Wellington Manoel dos Oliveira, José Dailson Silva de Gallo, Cibele Merched Lemos, Eurico Eduardo Pinto de 2022-12-28T13:53:48Zoai:ojs.pkp.sfu.ca:article/38756Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:52:20.682074Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
