Resumo: An investigation was carried out to study the effectiveness of the hydric stress test on the evaluation of the onion (Allium cepa L.) seed vigor. Six lots of onion seeds, cultivar "Pira Ouro", were submitted to several tests such as germination, first count, cold test, accelerated aging, electrical conductivity, field emergence and hydric stress at 0, -3, -6 and -9 atm potentials. The experiments were conducted at the Seed Analysis Laboratory and at the Experimental Field of the Escola Superior de Agricultura "Luiz de Queiroz"-ESALQ/USP. The results suggested that the hydric stress test at -3 atm potential was highly correlated with the field emergence and with the cold test. This test can be indicated to evaluate the vigor of onion seeds.

Foram avaliadas sementes de seis lotes da cultivar Pira Ouro, pelos testes de germinação, primeira contagem, de frio em solo, envelhecimento artificial, condutividade elétrica, emergência em campo, e estresse hídrico nos potenciais de 0, -3, -6 e -9 atm. Os experimentos foram conduzidos no Laboratório de Análise de Sementes e no campo experimental da Escola Superior de Agricultura "Luiz de Queiroz" - ESALQ/USP. O teste de estresse hídrico, no potencial de -3 atm, apresentou alta correlação com a emergência em campo e com o teste de frio, sendo indicado para avaliar o vigor de sementes de cebola.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPiana, ZenórioTillmann, Maria Angela Andreda Silva, Walter Rodrigues1995-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4371Pesquisa Agropecuaria Brasileira; v.30, n.6, jun. 1995; 867-873Pesquisa Agropecuária Brasileira; v.30, n.6, jun. 1995; 867-8731678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4371/1657info:eu-repo/semantics/openAccess2010-06-02T13:16:54Zoai:ojs.seer.sct.embrapa.br:article/4371Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-06-02T13:16:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
