Resumo: | Seeds with a good physiological quality are essential to high productivity. However, for some seeds, Phaseolus lunatus L., the viability and vigor analyze show deficiency in quality. This work aimed to evaluate the physiological quality of Phaseolus lunatus L. seeds using several vigor tests. The study was realized at the Laboratory of Seed Analysis of the Agricultural Sciences Center of the Federal University of Paraíba, in Areia – PB, Brazil. We used seeds from five cultivars of P. lunatus (Branca, Orelha de Vó, Cearense, Rosinha, and Roxinha). To determine the physiological quality, we measured the water content, the viability and vigor test (germination, emergence, electrical conductivity, tetrazolium, first germination count and emergence, seedling length and dry mass). We used a completely randomized design for seeds evaluation, and the field test was performed in randomized blocks. The water content of P. lunatus did not differ among the cultivars, indicating a uniformity in the percentage of moisture. Also, the percentage and speed of emergency and the dry mass of seedlings did not differ among the varieties. The tetrazolium and electrical conductivity tests indicated that Rosinha cultivar had the worst viability concerning the other cultivars, showing a low percentage of living tissue and lower electrical conductivity. The seeds of Roxinha cultivar had the better physiological quality, and the Cearense cultivar had the worst quality evaluation. We recommend the tetrazolium test but not the electrical conductivity test to evaluate the vigor of P. lunatus. |

Dessa forma, o objetivo neste trabalho foi avaliar a qualidade fisiológica das sementes de cultivares de Phaseolus lunatus por diferentes testes de vigor. A pesquisa foi realizada no Laboratório de Análise de Sementes do Centro de Ciências Agrárias da Universidade Federal da Paraíba, em Areia - PB, com sementes de cinco cultivares de Phaseolus lunatus (Branca, Orelha de Vó, Cearense, Rosinha e Roxinha). Para avaliação da qualidade fisiológica das sementes determinou-se o teor de água e realizou-se testes de viabilidade e vigor (germinação, emergência, condutividade elétrica, tetrazólio, primeira contagem de germinação e emergência, comprimento e massa seca de plântulas). O delineamento utilizado foi o inteiramente casualizado, com exceção dos testes realizados em campo, que foi em blocos ao acaso. O teor de água das sementes dos cultivares de feijão-fava não diferiu estatisticamente entre si, indicando que houve uniformidade na porcentagem de umidade. Não houve diferença significativa entre as sementes dos cultivares de feijão-fava quando avaliou-se a porcentagem e velocidade de emergência, bem como a massa seca de plântulas. Os resultados dos testes de tetrazólio e condutividade elétrica constatou-se maior viabilidade para as sementes do cultivar Roxinha, Branca, Cearense e Orelha de Vó quando comparadas com as da Rosinha, uma vez que houve um maior percentual de tecidos vivos e uma menor condutividade elétrica, respectivamente. As sementes do cultivar Roxinha são de melhor qualidade fisiológica e, o cultivar Cearense de pior qualidade; o teste de tetrazólio é recomendado para avaliação do vigor de sementes de cultivares de Phaseolus lunatus, enquanto, o teste de condutividade elétrica não é recomendado para avaliar o vigor das sementes dos cultivares de P. lunatus.EDUFU2019-10-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4230910.14393/BJ-v35n5a2019-42309Bioscience Journal ; Vol. 35 No. 5 (2019): Sept./Oct.; 1463-1469Bioscience Journal ; v. 35 n. 5 (2019): Sept./Oct.; 1463-14691981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/42309/27069Brazil; ContemporaryCopyright (c) 2019 Maria das Graças Rodrigues do Nascimento, Maria Lúcia Maurício da Silva, Edna Ursulino Alves, Caroline Marques Rodrigues, Maria Joelma da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNascimento, Maria das Graças Rodrigues doSilva, Maria Lúcia Maurício daAlves, Edna UrsulinoRodrigues, Caroline MarquesSilva, Maria Joelma da2022-01-26T03:31:25Zoai:ojs.www.seer.ufu.br:article/42309Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-26T03:31:25Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
