Resumo: The salinity of soil and water of irrigation can cause negative effects to agriculture by affecting the development and productivity of the cultivated species. These effects can be mitigated with the cultivation of salinity-tolerant varieties. The objective of this study was to evaluate the effect of salinity on the water imbibition curve during the germination process in cowpea seed and the response of different cultivars. An experiment was conducted in a factorial scheme, composed of three cultivars (BRS Marataoã, BRS Pajeu and BRS Tumucumaque) and four levels of salt stress, obtained by NaCl solutions at concentrations of 50, 100 and 150 mM and control, distilled water. The treatments were arranged in a completely randomized design, with four repetitions. The variables analyzed were the pattern of imbibition curve and final seed water content. It was found that the evaluated cultivars do not present the three-phase pattern for the seed soaking curve, in the absence or presence of salinity. There is variability for the pattern of the seed soaking curve among BRS Marataoã, BRS Pajeu and BRS Tumucumaque cowpea cultivars. Salinity acts by reducing the water content of cowpea seeds during the germination process and causes alteration in the pattern of the water soaking curve by the seeds. The cultivar BRS Tumucumaque shows higher tolerance to the reduction of seed water content under salt stress conditions when compared to the cultivars BRS Pajeu and BRS Marataoã.

Esses efeitos podem ser mitigados com o cultivo de variedades tolerantes à salinidade. O objetivo desse trabalho foi avaliar o efeito da salinidade sobre a curva de embebição de água durante o processo de germinação em sementes de distintas cultivares de feijão-caupi. Para isso, foi conduzido um experimento em esquema fatorial, composto por três cultivares (BRS Marataoã, BRS Pajeu e BRS Tumucumaque) e quatro níveis de estresse salino, induzidos por soluções de NaCl nas concentrações 50, 100 e 150 mM e o controle com água destilada. Os tratamentos foram dispostos em delineamento inteiramente casualizado, com quatro repetições. As variáveis analisadas foram o padrão de curva de embebição; e o conteúdo de água final das sementes. Constatou-se que as cultivares avaliadas não apresentam o padrão trifásico para a curva de embebição de sementes, na ausência ou na presença de salinidade. Há variabilidade para o padrão de curva de embebição de sementes entre as cultivares BRS Marataoã, BRS Pajeu e BRS Tumucumaque de feijoeiro-caupi. A salinidade atua reduzindo o conteúdo de água das sementes de feijão-caupi durante o processo de germinação e causa alteração no padrão da curva de embebição de água pelas sementes. A cultivar BRS Tumucumaque demonstra maior tolerância à redução do conteúdo de água da semente em condições de estresse salino, quando comparada às cultivares BRS Pajeu e BRS Marataoã.Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Cassilândia2023-08-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicosonline.uems.br/index.php/agrineo/article/view/755510.32404/rean.v10i3.7555Revista de Agricultura Neotropical; v. 10 n. 3 (2023): REVISTA DE AGRICULTURA NEOTROPICAL; e7555REVISTA DE AGRICULTURA NEOTROPICAL; Vol. 10 No. 3 (2023): REVISTA DE AGRICULTURA NEOTROPICAL; e75552358-6303reponame:Revista de Agricultura Neotropicalinstname:Universidade Estadual de Mato Grosso do Sul (UEMS)instacron:UEMSenghttps://periodicosonline.uems.br/index.php/agrineo/article/view/7555/5559https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCorreia de Souza, RaéderRomanoski, Vanessade Moura Souza Filho, Paulo Roberto Badaró Pimentel, Adérico Júnior2023-08-30T15:18:45Zoai:ojs.pkp.sfu.ca:article/7555Revistahttps://periodicosonline.uems.br/index.php/agrineoPUBhttps://periodicosonline.uems.br/index.php/agrineo/oaiagriculturaneotropical@uems.br || wellingthon.junnyor@uems.br2358-63032358-6303opendoar:2023-08-30T15:18:45Revista de Agricultura Neotropical - Universidade Estadual de Mato Grosso do Sul (UEMS)false
