Resumo: | Salt stress negatively affects plant development, mainly in arid and semiarid regions, promoting changes in their physiology and productivity. The objective of this study was to evaluate the germinative potential of creole maize (Zea mays L.) and fava bean (Phaseolus lunatus L.) seeds under different salt stress conditions. The seeds were collected in rural areas of the municipalities of Guanambi, Candiba, and Brumado, which are within the Serra Geral region in the state of Bahia, Brazil. A completely randomized experimental design was used; the treatments consisted of three salts (CaCl2, MgCl2, and NaCl) and four salinity levels (osmotic potentials of -0.3, -0.9, and -1.2 MPa). Seed physical analyses included moisture and purity, and physiological analyses included germination percentage, germination speed index, average germination time, and relative germination frequency. The storage of creole maize and fava bean seeds in plastic bottles and under adequate humidity ensures that seeds will have moisture content and physical purity within ideal values. Salt stresses induced by NaCl and CaCl2 salts at osmotic potentials of -0.3 to -1.2 MPa hinder the creole maize and fava bean seed germination, and their germination are null for both salts at osmotic potentials lower than -0.3 MPa. The creole maize and fava bean seeds show germination of 70% under salt stress induced by MgCl2 at osmotic potential of -0.3 MPa, making the germination of both species viable. |

Objetivou-se avaliar o potencial germinativo de sementes crioulas de milho (Zea mays L.) e feijão-fava (Phaseolus lunatus L.) em condições de estresse salino, com diferentes potenciais e sais. As sementes foram coletadas em áreas rurais, nos municípios de Guanambi, Candiba e Brumado, região do Brasil que corresponde a Serra Geral da Bahia. O delineamento experimental foi inteiramente casualizado e os tratamentos constituíram-se por três sais CaCl2, MgCl2 e NaCl, além de quatro potenciais de salinidade 0; -0,3; -0,9 e -1,2 MPa. As análises físicas das sementes incluíram umidade e pureza física, enquanto que as análises fisiológicas foram: porcentagem de germinação, índice de velocidade de germinação, tempo médio de germinação e frequência relativa de germinação. O armazenamento das sementes crioulas de feijão-fava e milho feito em garrafas pet com volume totalmente preenchido somado à colheita com a umidade adequada, garante que as sementes apresentem grau de umidade e pureza física dentro dos valores considerados ideias. O estresse salino induzido pelos sais NaCl e CaCl2, com potenciais osmóticos entre -0,3 e -1,2 MPa é prejudicial à germinação de sementes crioulas de feijão-fava e milho, e em potenciais menores que -0,3 MPa a germinação é nula para ambos os sais. As sementes crioulas de milho e feijão-fava apresentam germinação de 70% na solução de MgCl2 no potencial osmótico de -0,3 MPa, nesta condição a germinação de ambas às espécies é viável.Universidade Federal Rural do Semi-Árido2020-07-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/900010.1590/1983-21252020v33n329rcREVISTA CAATINGA; Vol. 33 No. 3 (2020); 853-859Revista Caatinga; v. 33 n. 3 (2020); 853-8591983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/9000/10299Copyright (c) 2020 Revista Caatingainfo:eu-repo/semantics/openAccessAlmeida, Carla de SouzaGuariz, Hugo RoldiPinto, Marília Alves BritoAlmeida, Marineide Ferreira de 2023-07-21T17:16:07Zoai:ojs.periodicos.ufersa.edu.br:article/9000Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:44.689199Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
