Resumo: | The seminiferous propagation of Carica papaya L. presents a mixture of genotypes with a strong influence on fruit production costs, quality and yield, prevailing due to the lack of efficient protocols for vegetative propagation. In this context, the tissue culture emerges as a promising alternative, because it can provide, to farmers, sex determination in seedlings, with a high quality standard and enough amounts to supply commercial demands in all seasons. This study aimed at developing an in vitro micropropagation protocol from young papaya material, in two experiments. In the first experiment, the explants were multiplied in vitro and the cytokinins BAP, 2iP and KIN were tested at the concentrations of 0.0 mg L-1, 2.5 mg L-1, 5.0 mg L-1 and 10.0 mg L-1, with the best results observed for 2iP, especially at the 2.5 mg L-1 concentration. In the second one, the 2iP cytokinin was used at the concentrations of 0.0 mg L-1, 1.0 mg L-1, 2.0 mg L-1 and 4.0 mg L-1, with and without GA3 (0.0 mg L-1 and 1.0 mg L-1), with beneficial effects of GA3 observed in the multiplication process, especially when combined with 1.0 mg L-1 of 2iP, with the best results for plants height, number of leaves and explants sprouting. |

Neste contexto, a cultura de tecidos surge como uma alternativa promissora, pois poderá fornecer aos produtores mudas com sexo definido, alto padrão de qualidade e em quantidade suficiente para atender à demanda comercial, em qualquer época do ano. Este trabalho objetivou desenvolver um protocolo de multiplicação in vitro, a partir de material juvenil de mamoeiro, em dois experimentos. No primeiro, os explantes foram multiplicados in vitro, testando-se as citocininas BAP, 2iP e CIN, nas concentrações de 0,0 mg L-1, 2,5 mg L-1, 5,0 mg L-1 e 10,0 mg L-1, com o melhor desenvolvimento sendo observado para 2iP, sobretudo na concentração de 2,5 mg L-1. No segundo, foi utilizada a citocinina 2iP, nas concentrações de 0,0 mg L-1, 1,0 mg L-1, 2,0 mg L-1 e 4,0 mg L-1, com e sem GA3 (0,0 mg L-1 e 1,0 mg L-1), constatando-se o efeito benéfico do GA3 na multiplicação, especialmente quando combinado com 1,0 mg L-1 de 2iP, sendo observados os melhores resultados para altura, número de folhas e brotações dos explantes.Escola de Agronomia - Universidade Federal de Goiás2013-04-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/19611Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 43, n. 1, Jan./Mar. 2013; 64-70Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 43, n. 1, jan./mar. 2013; 64-70Pesquisa Agropecuária Tropical; v. 43, n. 1, jan./mar. 2013; 64-701983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/19611/13899Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessVidal, Francisco RonaldoDiniz, Josefa Diva NogueiraSilva, Fanuel Pereira da2020-07-10T12:08:19Zoai:ojs.revistas.ufg.br:article/19611Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:57.200592Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
