Resumo: | Popularly identified as official-of-room or false-weed, Asclepias curassavica L. is an annual, latent, erect, small plant, whose height, depending on environmental conditions, varies between 40 and 80 cm. Pasture weed, considered highly toxic to cattle, although it also has medicinal properties, it is frequently used to kill worms and, in moderate doses, is purgative. The study and formation of a crop begins with the production of seedlings, and the quality of the propagation material is decisive. At the same time, during the storage period, it is essential to control both the physiological and sanitary quality of the seed. Pre-hydration is usually a procedure adopted to harmonize emergence, especially in wild seeds. The objective was, at present study, to evaluate hydration times in the moisture gain and vigor of the seeds, using a randomized block design, with three replications, in which the treatments corresponded to a 4 x 2 factorial arrangement, resulting from the combination of the factors of time of hydration (zero, two, four, and six hours) and seed age (newly harvested; two years old) in the wild species oficial de sala. In the germination pattern, young and old seeds behaved little differently in terms of hydration times. Seed hydration contributes to harmonizing germination and, for six hours, it allows germination of around 84% in new seeds, being innocuous in old seeds, which proved to be unviable. |

Hierba de pasto, considerada altamente tóxica para el ganado, aunque también tiene propriedades medicinales, usado frecuentemente casi siempre se usa para matar gusanos y, en dosis moderadas, es purgante. El estudio y formación de un cultivo comienza con la producción de plántulas, y la calidad del material de propagación es determinante. Al mismo tiempo, durante el período de almacenamiento, es fundamental controlar la calidad tanto fisiológica como sanitaria de la semilla. La prehidratación suele ser un procedimiento adoptado para armonizar la emergencia, especialmente en semillas silvestres. El objetivo fue, en la actualidad, evaluar tiempos de hidratación en ganancia de humedad y vigor de las semillas, utilizando un diseño de bloques al azar, con tres repeticiones, en el que los tratamientos correspondieron a un arreglo factorial 4 x 2, resultante de la combinación de los factores de tiempo de hidratación (cero, dos, cuatro y seis horas) y edad de la semilla (recién cosechada; dos años) en la especie silvestre oficial de sala. En el patrón de germinación, las semillas jóvenes y viejas se comportaron de manera poco diferente en términos de tiempos de hidratación. La hidratación de las semillas contribuye a armonizar la germinación y, durante seis horas, permite germinar alrededor del 84% en semillas nuevas, siendo inocuo en semillas viejas, que resultaron ser inviables.Identificada popularmente como oficial-de-sala ou falsa-erva-de-rato, a Asclepias curassavica L., é uma planta anual, latescente, ereta, de pequeno porte, cuja altura, dependendo das condições ambientais varia entre 40 e 80 cm. Infestante de pastagens, considerada altamente tóxica a bovinos, muito embora também ostente propriedades medicinais, é frequentemente utilizada para matar bernes e, em dose moderada, é purgativa. O estudo e formação de um cultivo tem início na produção de mudas, sendo, determinante, a qualidade do material de propagação. Ao mesmo tempo, durante o período de armazenamento é imprescindível controlar tanto a qualidade fisiológica como a sanitária da semente. A pré-hidratação costuma ser um procedimento adotado para harmonizar a emergência, sobretudo em sementes silvestres. Objetivou-se, no presente estudo, avaliar tempos de hidratação no ganho de umidade e vigor das sementes, utilizando o delineamento em blocos ao acaso, com três repetições, no qual os tratamentos corresponderam a um arranjo fatorial 4 x 2, resultantes da combinação dos fatores tempo de hidratação (zero, duas, quatro e seis horas) e idade da semente (recém-colhida; dois anos de idade) na espécie silvestre oficial de sala. No teste padrão de germinação, sementes novas e velhas se comportaram de modo pouco diverso diante dos tempos de hidratação. A hidratação das sementes contribui para harmonizar a germinação e, por seis horas possibilita germinação em torno de 84 % em sementes novas, sendo inócua em sementes velhas, que se mostraram inviáveis.Research, Society and Development2022-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2720410.33448/rsd-v11i4.27204Research, Society and Development; Vol. 11 No. 4; e33611427204Research, Society and Development; Vol. 11 Núm. 4; e33611427204Research, Society and Development; v. 11 n. 4; e336114272042525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/27204/24223Copyright (c) 2022 Cristovam Colombo Belfort; Flávia da Silva Soares; Pedro Emartino Bezerra Campelo; Eulina Barbosa Nery; Endrigho de Alcântara Uchôa Belfort; Francisco Alves de Sousa Netohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBelfort, Cristovam Colombo Soares, Flávia da Silva Campelo, Pedro Emartino Bezerra Nery, Eulina Barbosa Belfort, Endrigho de Alcântara Uchôa Sousa Neto, Francisco Alves de 2022-03-27T17:17:09Zoai:ojs.pkp.sfu.ca:article/27204Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:45:01.002262Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
