Resumo: | Soil salinization is an environmental factor that frequently occurs in semi-arid regions around the world and seed priming technique is one of the alternatives to obtain the greatest establishment of seedlings in the field, through the induction of tolerance to environmental stresses. This research aimed to evaluate the effect of seed priming with NaCl on the induction of salinity tolerance in Myracrodruon urundeuva Allemão in vitro. The research was carried out at the Center for Strategic Technologies of the Northeast, in Recife / PE-Brazil M. urundeuva seeds were disinfected and submitted to two treatments: water (control) or NaCl (2mM), and inoculated in WPM medium at three saline concentrations (0.0; 25.0 and 50.0 mM NaCl) for 45 days. Plant height, number of leaves, fresh biomass (total, shoot, and root), shoot/root ratio, sodium and potassium and Na/K ratio, antioxidant enzyme activity, and peroxide content were evaluated malondialdehyde hydrogen. The data were subjected to variance analysis and the results were compared using the Student-Newman-Keuls test at 5% probability, using the R software. Seed priming with NaCl promoted a beneficial effect on the height of seedlings exposed to salinity. On the other hand, height was inversely proportional to saline concentrations, regardless of seed priming. The shoot/root ratio was also lower in seedlings cultivated under 25 and 50 mM NaCl. Despite being favorable for most growth variables, seed priming with NaCl induced an increase in lipid peroxidation in seedlings that were not exposed to salinity, which is linked to a decrease in the activity of antioxidant enzymes. The antagonistic response to NaCl stimulation between growth parameters and plant defense observed in the present research raises the need for further complementary studies that make it possible to delineate the metabolic alterations of M. urundeuva against a chemical stimulus to induce tolerance to a given stress. |

Este trabalho objetivou avaliar o efeito do seed priming com NaCl na indução da tolerância à salinidade em Myracrodruon urundeuva Allemão in vitro. A pesquisa foi realizada no Centro de Tecnologias Estratégicas do Nordeste, em Recife / PE-Brasil. Sementes de M. urundeuva foram desinfestadas e submetidas a dois tratamentos: água (controle) ou NaCl (2mM), e inoculadas em meio WPM em três concentrações salinas (0.0; 25.0 and 50.0 mM NaCl) por 45 dias. Foi avaliada a altura, número de folhas, biomassa fresca (total, parte aérea e raiz), razão parte aérea / raiz, sódio, potássio, razão Na / K, atividade de enzimas antioxidantes, teores de peróxido de hidrogênio e malondialdeído. Os dados foram submetidos à análise de variância e os resultados comparados pelo teste Student-Newman-Keuls a 5% de probabilidade, utilizando o software R. O priming com NaCl promoveu efeito benéfico na altura de mudas expostas à salinidade. Todavia, a altura foi inversamente proporcional às concentrações salinas, independentemente do priming. A razão parte aérea / raiz foi menor nas mudas cultivadas sob NaCl 25 e 50 mM. Apesar de ser favorável para a maioria das variáveis de crescimento, o seed priming com NaCl induziu aumento na peroxidação lipídica em mudas não expostas à salinidade, o que está relacionado à diminuição da atividade de enzimas antioxidantes. A resposta antagônica à estimulação do NaCl entre parâmetros de crescimento e defesa das plantas na presente pesquisa levanta a necessidade de novos estudos complementares que possibilitem delinear as alterações metabólicas de M. urundeuva frente a um estímulo químico para induzir tolerância a um determinado estresse.Universidade Federal de Santa Maria2022-11-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6760010.5902/1980509867600Ciência Florestal; Vol. 32 No. 4 (2022); 2199-2218Ciência Florestal; v. 32 n. 4 (2022); 2199-22181980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/cienciaflorestal/article/view/67600/49477https://periodicos.ufsm.br/cienciaflorestal/article/view/67600/52412Copyright (c) 2022 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessSouza, Lindomar Maria deConceição, Emanuella Maria daBarbosa, Marta RibeiroPalhares Neto, LuizSantos, Ana Maria Maciel dosSouza, Robson Antonio deHoullou, Laureen Michelle2023-04-14T15:21:32Zoai:ojs.pkp.sfu.ca:article/67600Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-04-14T15:21:32Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
