Resumo: | Chamaecrista rotundifolia is a legume of high yield and nutritional value for livestock; however, it presents high seed dormancy. The aim of this study was to evaluate dormancy-breaking methods and the influence of soil texture on seedling emergence and initial development of C. rotundifolia. The experiment was performed in a greenhouse in a split-plot design with five replications. There were three treatments including dormancy-breaking techniques with immersion of the seeds in (1) hot water at 80°C for 30 s followed by 12 h in water at room temperature (25 °C; HW); (2) water at room temperature (25 °C) for 24 h (EW); and (3) hydrochloric acid (0.05 mol L-1) for 15 min (HA) (4) and a control group with no seed intervention, disposed in the main plots in randomized blocks. Seeds were cropped in two types of soil as subplots. Seedling emergence was evaluated daily to calculate the percentage emergence and emergence speed index. Plant performance was evaluated (21 days after sowing) through measurements of mass and length of components. Chamaecrista rotundifolia showed a high degree of dormancy in the seeds, and the treatment using HW had greater efficiency in seedling emergence (p < 0.01) and emergence speed index (p < 0.05). Total dry mass was superior in sandy soil (p < 0.05). Soil texture and dormancy treatments influenced the initial performance of plants, which performed better in sandy soil.Key words: germination; legume; sandy; seed; soil texture. |

O objetivo foi avaliar métodos de superação de dormência e a influência da textura do solo na emergência das plântulas e desempenho inicial. O experimento foi realizado em casa de vegetação em delineamento com parcelas subdivididas e cinco repetições. Os tratamentos consistiram em técnicas de superação de dormência com a imersão das sementes em (1) água quente a 80°C por 30 s seguida pela imersão em água a temperatura ambiente por 12 h; (2) imersão em água a temperatura ambiente (25 °C) por 24 h e (3) imersão em ácido clorídrico (0,05 mol L-1) por 15 min, e um grupo controle (sem intervenção nas sementes), dispostos nas parcelas em blocos casualizados. As sementes foram cultivadas em dois solos como subparcelas. Foi avaliada a emergência diária das mudas para calcular o percentual e o índice de velocidade de emergência. Aos 21 dias após a semeadura, o desempenho da planta foi avaliado por meio de medidas e massa dos componentes. O tratamento com água quente apresenta maior eficiência em promover a emergência de plântulas (p < 0,01) e no índice de velocidade de emergência (p<0,05). O total de massa seca se destacou em solo arenoso (p < 0,05). A textura do solo influencia os tratamentos de superação de dormência nos parâmetros de desempenho inicial das plantas, sendo observado melhor desempenho em solo arenoso.Palavras-chave: germinação; leguminosa; arenoso, semente; textura de solo.Universidade Federal de Goiás2021-03-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://revistas.ufg.br/vet/article/view/66677Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 22 (2021): Continuous publicationCiência Animal Brasileira / Brazilian Animal Science; v. 22 (2021): Publicação contínua1809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporenghttps://revistas.ufg.br/vet/article/view/66677/36405https://revistas.ufg.br/vet/article/view/66677/36794https://revistas.ufg.br/vet/article/view/66677/36407https://revistas.ufg.br/vet/article/view/66677/36795Copyright (c) 2021 Ciência Animal Brasileirahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessdo Nascimento Gomes , Josilene Lima Abreu, NatanLucélia da Silva Nascimento , Angélica Muniz Rocha , SaraRodrigues de Quadros , Barbara de Abreu Faria, Letícia 2023-03-23T18:53:00Zoai:ojs.revistas.ufg.br:article/66677Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:26.812086Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
