Resumo: The use of cultivars tolerant to salinity is one of the strategies for food production in regions affected by soil salinization. The objective of this study was to evaluate the tolerance of pepper cultivars to saline stress during the process of seed germination and seedling development. The experiment was conducted in the laboratory, adopting a completely randomized design, in a factorial scheme, with four replicates. The first factor consisted of two pepper cultivars (Casca Dura Ikeda and Amarelo SF 134); and the second five levels of water salinity (0.0; 3.0; 6.0; 9.0 and 12.0 dS m-1). Germination, first germination count, germination speed index, average germination time, seedling length, root and shoot dry matter and salinity tolerance index were evaluated. In general, the salinity of the water promoted deleterious effects on the germination and seedling growth of the two cultivars from the EC 6.0 dS m-1. The cultivar ‘Amarelo SF 134’ indicates greater tolerance to salt stress in the germination process, while ‘Casca Dura Ikeda’, in the initial seedling growth phase.

El objetivo de este estudio fue evaluar la tolerancia de cultivares de pimiento al estrés salino durante el proceso de germinación de semillas y desarrollo de plántulas. El experimento se realizó en un laboratorio, adoptando un diseño completamente al azar, en un esquema factorial, con cuatro repeticiones. El primer factor consistió en dos cultivares de pimiento (Casca Dura Ikeda y Amarelo SF 134); y el segundo, por cinco niveles de salinidad del agua (0.0; 3.0; 6.0; 9.0 y 12.0 dS m-1). Se evaluó la germinación, primer conteo de germinación, índice de velocidad de germinación, tiempo promedio de germinación, longitud de plántula, materia seca de raíces y brotes e índice de tolerancia a la salinidad. En general, la salinidad del agua promovió efectos deletéreos sobre la germinación y el crecimiento de las plántulas de los dos cultivares de la CE 6.0 dS m-1. El 'Yellow SF 134' indica tolerancia al estrés salino en el proceso de germinación, mientras que el 'Bark Hard Ikeda', en la fase inicial de crecimiento de la plántula.A utilização de cultivares tolerantes à salinidade é uma das estratégias para a produção de alimentos em regiões afetadas pela salinização do solo. Objetivou-se com este estudo avaliar a tolerância de cultivares de pimentão ao estresse salino durante o processo de germinação das sementes e desenvolvimento das plântulas. O experimento foi conduzido em laboratório, adotando-se delineamento inteiramente aleatorizado, em esquema fatorial, com quatro repetições. O primeiro fator foi constituído por duas cultivares de pimentão (Casca Dura Ikeda e Amarelo SF 134); e o segundo, por cinco níveis de salinidade da água (0,0; 3,0; 6,0; 9,0 e 12,0 dS m-1). Avaliou-se a germinação, primeira contagem de germinação, índice de velocidade de germinação, tempo médio de germinação, comprimento de plântula, massa seca da raiz e parte aérea e índice de tolerância à salinidade. De forma geral, a salinidade da água promoveu efeitos deletérios na germinação e crescimento de plântulas das duas cultivares a partir da CE 6,0 dS m-1. A ‘Amarelo SF 134’ indica apresentar tolerância ao estresse salino no processo germinativo, enquanto a ‘Casca Dura Ikeda’, na fase de crescimento inicial de plântulas.Research, Society and Development2021-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1385110.33448/rsd-v10i4.13851Research, Society and Development; Vol. 10 No. 4; e9110413851Research, Society and Development; Vol. 10 Núm. 4; e9110413851Research, Society and Development; v. 10 n. 4; e91104138512525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/13851/12453Copyright (c) 2021 Maiara Pereira Barros; Marcelo de Almeida Guimarães ; Francisco Ronaldo Alves de Oliveira; Haynna Fernandes Abud ; Charles Lobo Pinheiro; Maria Gina Torres Sena; Hozano de Souza Lemos Neto; Carlos Tadeu dos Santos Diashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBarros, Maiara Pereira Guimarães , Marcelo de AlmeidaOliveira, Francisco Ronaldo Alves de Abud , Haynna FernandesPinheiro, Charles LoboSena, Maria Gina Torres Lemos Neto, Hozano de SouzaDias, Carlos Tadeu dos Santos 2021-04-25T11:21:26Zoai:ojs.pkp.sfu.ca:article/13851Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:06.433657Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
