Resumo: | The objective of this paper was to determine the physiological behavior and seed quality of five genotypes of Acca sellowiana regarding desiccation. Seeds were obtained from five plants of urban backyards in the cities of Dois Vizinhos - PR (A1, A2) and Vacaria - RS (A3, A4, A5). The experiment was conducted in a bifactor arrangement (5x3), with five genotypes and three levels of water content (28%, 15% and 5%), arranged into complete randomized block design, with four replicates of 50 seeds each. Seeds were germinated on absorbent paper soaked with water, being kept in BOD chamber under temperature of 25±3°C with photoperiod of 16 hours. Germination percentage, speed index and average time were assessed by counting seeds every two days for 50 days, starting from the moment of radicle emergence. No significant differences were observed for germination percentage and all genotypes surpassing 79% of germination. Desiccation of seeds had low influence on germination speed index and average time of germination, although genotype influence was verified due to genetic variability. Genotype A5 has seeds with superior quality from the others. Acca sellowiana seeds have orthodox behavior. |

Las semillas se obtuvieron de cinco plantas de jardín urbano en las ciudades de Dois Vizinhos - PR (A1, A2) y Vacaria - RS (A3, A4, A5). El experimento se realizó en un arreglo bifatorial (5x3), con cinco genotipos y tres contenidos de agua (28%, 15% y 5%), organizados en bloques totalmente aleatorios, con cuatro repeticiones de 50 semillas cada una. Las semillas fueron germinadas en papel absorbente, empapadas con agua y mantenidas en una cámara DBO a una temperatura de 25±3ºC con un fotoperíodo de 16 horas. Se evaluaron el porcentaje de germinación, el índice de velocidad de germinación y el tiempo medio de germinación contando las semillas cada dos días durante 50 días a partir de la emisión de la radícula. No se observaron diferencias significativas en cuanto al porcentaje de germinación, que supera el 79% de todos los genotipos. La desecación de las semillas influyó poco en la tasa de germinación y en el tiempo medio de germinación, aunque el genotipo se vio influido por la variabilidad genética. El genotipo A5 tiene semillas de calidad superior a las otras. Las semillas de A. sellowiana tienen un comportamiento ortodoxo.Este trabalho teve como objetivo determinar o comportamento fisiológico e a qualidade de sementes de cinco genótipos de Acca sellowiana quanto à dessecação. As sementes foram obtidas de cinco plantas de quintais urbanos nos municípios de Dois Vizinhos - PR (A1, A2) e Vacaria - RS (A3, A4, A5). O experimento foi realizado em arranjo bifatorial (5x3), sendo cinco genótipos e três teores de água (28%, 15% e 5%), organizado em blocos inteiramente casualizados, com quatro repetições de 50 sementes cada. As sementes foram germinadas em papel absorvente, embebido com água, e mantidas em câmara BOD a temperatura de 25±3ºC com fotoperíodo de 16 horas. Foram avaliadas a porcentagem de germinação, índice de velocidade de germinação e tempo médio de germinação, pela contagem das sementes a cada dois dias, por 50 dias a partir da emissão da radícula. Não foram observadas diferenças significativas para porcentagem de germinação, ultrapassando 79% de todos os genótipos. A dessecação das sementes teve baixa influência no índice de velocidade de germinação e tempo médio de germinação, apesar de verificada influência do genótipo em função da variabilidade genética. O genótipo A5 possui sementes com qualidade superior as demais. As sementes de A. sellowiana possuem comportamento ortodoxo.Research, Society and Development2020-07-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/545810.33448/rsd-v9i8.5458Research, Society and Development; Vol. 9 No. 8; e681985458Research, Society and Development; Vol. 9 Núm. 8; e681985458Research, Society and Development; v. 9 n. 8; e6819854582525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/5458/5809Copyright (c) 2020 Moeses Andrigo Danner, Marciele Felippi, Ana Elisia Sohne, Alexandre Giesel, Larissa Corradi Voss, Joel Donazzolohttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessVoss, Larissa CorradiFilippi, MarcieleSohne, Ana ElisiaDanner, Moeses AndrigoGiesel, AlexandreDonazzolo, Joel2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/5458Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:58.119778Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
