Resumo: | Salinity problems are increasing in the semi-arid regions of northeastern Brazil. Thus, detailed studies of the region’s cultured crops, primarily salt-tolerant species, are important. Therefore, the aim of the present study was to evaluate the salt stress tolerance of lima bean (Phaseolus lunatus L.) seeds at different temperatures. This study was conducted in the Seed Analysis Laboratory, Agricultural Sciences Center, Federal University of Paraíba (Areia, PB, Brazil) by using seeds of four lima bean cultivars (Branca, Orelha de Vó, Rosinha, and Roxinha) in a randomized experimental design. Sodium chloride (NaCl) was used as a solute for salt-stress simulation at the following concentrations: 0.0 (control), 1.5, 3.0, 4.5, 6.0, 7.5, and 9.0 dS m-1; temperatures were maintained constant at 25°C, 30°C, and 35°C. Germination and vigor tests were performed to evaluate the treatment effects (first count, germination rate index, seedling length, and dry matter). Germination rate of lima bean seeds increased in salt concentrations up to 9 dS m-1, and seeds of Roxinha cultivar exhibited the highest salinity tolerance. The development of lima bean cultivar seedlings was negatively affected at 35°C under high-salinity conditions. |

Nesse sentido, o objetivo com este trabalho foi avaliar à tolerância de sementes de cultivares de feijão-fava (Phaseolus lunatus L.) a condição de estresse salino em diferentes temperaturas. O trabalho foi realizado no Laboratório de Análise de Sementes do Centro de Ciências Agrárias da Universidade Federal da Paraíba, em Areia, PB, com sementes de quatro cultivares de feijão-fava (Branca, Orelha de Vó, Rosinha e Roxinha), em delineamento experimental inteiramente ao acaso. Para simulação do estresse salino, utilizou-se como soluto o cloreto de sódio (NaCl), nas concentrações de 0,0 (testemunha); 1,5; 3,0; 4,5; 6,0; 7,5 e 9,0 dS m-1 submetidas a temperaturas constantes de 25, 30 e 35 °C. Na avaliação do efeito dos tratamentos, realizou-se teste de germinação e vigor (primeira contagem e índice de velocidade de germinação, comprimento e massa seca de plântulas). A germinação de sementes dos cultivares de feijão-fava (Phaseolus lunatus L.) é elevada quando submetidas a concentrações salinas de até 9 dS m-1, sendo as sementes do cultivar Roxinha as mais tolerantes à salinidade simulada com cloreto de sódio. A temperatura de 35 °C não favorece o desenvolvimento das plântulas em condições salinas para todos os cultivares avaliados.Universidade Federal Rural do Semi-Árido2017-03-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/563110.1590/1983-21252017v30n322rcREVISTA CAATINGA; Vol. 30 No. 3 (2017); 738-747Revista Caatinga; v. 30 n. 3 (2017); 738-7471983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5631/pdfNascimento, Maria das Graças Rodrigues doAlves, Edna UrsulinoSilva, Maria Lúcia Maurício daRodrigues, Caroline Marquesinfo:eu-repo/semantics/openAccess2023-07-20T11:18:54Zoai:ojs.periodicos.ufersa.edu.br:article/5631Revistahttps://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:2024-04-29T09:46:23.218072Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
