Resumo: | The allelopathic activity of oils acts directly in seedling germination and growth processes, affecting the initial development, since the constitution and the class to which these oils belong are directly related to the harmful effects to the seeds. The present work aimed to analyze the allelopathic effect of copaíba oil on seed germination and initial development of tomato seedlings. The seeds of two lots were placed to germinate in a substrate moistened with 0; 0.01; 0.05; 0.10; 0.15 and 0.20% copaíba oil. 200 tomato seeds were used per treatment, distributed in four replications. Germination, germination speed index and seedling length were evaluated. The germination percentage and the germination speed index of the seeds of the two batches did not differ from each other, however seeds from batch 1 responded positively to the application of copaíba oil. Regarding the length of seedlings, the concentration of 0.01% was higher than the others. With regard to lot 2, the absence of copaíba oil provided a longer seedling length. The concentrations of copaíba oil did not reduce the percentage of germination, germination speed index in a positive way. For the observation of the allelopathic effect of copaíba oil on tomato seeds, it is recommended to use concentrations higher than those used in the present study. |

El presente trabajo tuvo como objetivo analizar el efecto alelopático del aceite de copaíba sobre la germinación de semillas y el desarrollo inicial de plántulas de tomate. Las semillas de dos lotes se colocaron para germinar en un sustrato humedecido con 0; 0,01; 0,05; 0,10; 0.15 y 0.20% de aceite de copaíba. Se utilizaron 200 semillas de tomate por tratamiento, distribuidas en cuatro repeticiones. Se evaluó la germinación, el índice de velocidad de germinación y la longitud de las plántulas. El porcentaje de germinación y el índice de velocidad de germinación de las semillas de los dos lotes no difirieron, sin embargo las semillas del lote 1 respondieron positivamente a la aplicación de aceite de copaíba. En cuanto a la longitud de las plántulas, la concentración de 0.01% fue mayor que las demás. Con respecto al lote 2, la ausencia de aceite de copaíba proporcionó una plántula de mayor longitud. Las concentraciones de aceite de copaíba no redujeron el porcentaje de germinación, índice de velocidad de germinación de manera positiva. Para la observación del efecto alelopático del aceite de copaíba sobre las semillas de tomate, se recomienda utilizar concentraciones superiores a las utilizadas en el presente estudio.As atividades alelopática de óleos atuam diretamente em processos de germinação e crescimento de plântulas, afetando o desenvolvimento inicial, uma vez que a constituição e a classe a que pertencem tais óleos estão diretamente relacionados aos efeitos nocivos às sementes. O presente trabalho teve como objetivo analisar o efeito alelopático do óleo de copaíba sobre a germinação de sementes e desenvolvimento inicial de plântulas de tomate. As sementes de dois lotes foram colocadas para germinar em substrato umedecido com 0; 0,01; 0,05; 0,10; 0,15 e 0,20% de óleo de copaíba. Foram utilizadas 200 sementes de tomate por tratamento, distribuídas em quatro repetições. Avaliou-se a germinação, o índice de velocidade de germinação e o comprimento de plântulas. A porcentagem de germinação e o índice de velocidade de germinação das sementes dos dois lotes não diferiram entre si, no entanto sementes do lote 1 responderam de forma positiva à aplicação do óleo de copaíba. Em relação ao comprimento de plântulas, a concentração de 0,01% foi superior às demais. No que se refere ao lote 2, a ausência do óleo de copaíba proporcionou um maior comprimento de plântulas. As concentrações de óleo de copaíba não reduziram a porcentagem de germinação, índice de velocidade de germinação de maneira positiva. Para a observação do efeito alélopatico do óleo de copaíba em sementes de tomate, recomenda-se a utilização de concentrações superiores às que foram utilizadas no presente estudo.Research, Society and Development2021-03-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1326610.33448/rsd-v10i3.13266Research, Society and Development; Vol. 10 No. 3; e24710313266Research, Society and Development; Vol. 10 Núm. 3; e24710313266Research, Society and Development; v. 10 n. 3; e247103132662525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/13266/11949Copyright (c) 2021 Rayane Monique Sete da Cruz; Renata Cristiane Pereira; Breno Gabriel da Silva; Rayssa Fernanda dos Santos; Alessandro Lucca Braccini; Lucio Cardozo Filho; Diego Eduardo Romero Gonzaga; Murilo Fuentes Pelloso; Nathália Maria Rizzo; Silas Maciel de Oliveira; Yana Miranda Borgeshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCruz, Rayane Monique Sete da Pereira, Renata Cristiane Silva, Breno Gabriel da Santos, Rayssa Fernanda dos Braccini, Alessandro Lucca Filho, Lucio Cardozo Gonzaga, Diego Eduardo Romero Pelloso, Murilo Fuentes Rizzo, Nathália MariaOliveira, Silas Maciel de Borges, Yana Miranda 2021-03-28T12:03:35Zoai:ojs.pkp.sfu.ca:article/13266Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:39.296999Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
