Resumo: | A trial was carried out in Piracicaba, São Paulo, Brazil, with the purpose of determining, comparatively, the best vigor tests for mechanically delinted cotton (Gossypium hirsutum L.) seeds. It consisted of a field experiment and six monthly spaced (from November 1974 to April 1975) laboratory and field plot tests. The seeds used were of the IAC 13-1 and IAC RM 3 cultivars, stored in dry chamber and in laboratory conditions with no temperature and humidity control. The following tests were performed: emergence percentage, velocity of emergence, first count in the germination test and rapid aging. The emergence percentage test was done in field plots; the final germination percentage was calculated for each treatment. The velocity of emergence was determined in the same test and the velocity index was calculated. The data of the first count (four days) of the germination test were used as a vigor test. For each time interval (month, four rapid aging) tests were done, being the seeds kept in the rapid aging chamber for 36, 48, 60 and 72 hours. After that, germination tests were made. The analysis and interpretation of the results allowed for the following main conclusions: the emergence percentage test can substitute the velocity of emergence test; the first count of the germination test was found to be inaquate as a vigor test; rapid aging in the aging chamber for 72 hours was found to be most suitable for cotton-seeds among the various tests studied; it was not detected any influence of seed vigor on the field yield. |

Foram utilizadas sementes das cultivares IAC 13-1 e IAC RM 3, armazenadas em dois ambientes diversos: câmara seca, e ambiente de laboratório sem controle de umidade e temperatura, tendo sido experimentados os seguintes testes: porcentagem e velocidade de emergência, primeira contagem do teste de germinação, teste de germinação e envelhecimento rápido. O teste de porcentagem de emergência foi instalado em canteiros, calculando-se o índice de velocidade de emergência; nos testes de germinação, a primeira contagem, 4 dias após a instalação, foi utilizada como teste de vigor; foram efetuados quatro testes de envelhecimento rápido, em cada uma das seis épocas, com permanência das sementes, na câmara de envelhecimento rápido, de 36, 48, 60 e 72 horas, após o que eram instalados testes de germinação. As análises e interpretações dos resultados permitiram as seguintes conclusões principais: o teste de porcentagem de emergência revelou-se capaz de substituir o de velocidade de emergência; a primeira contagem do teste de germinação revelou-se inadequada como teste de vigor; entre es testes utilizados, o de envelhecimento rápido, com 72 horas de permanência das sementes na câmara, foi o mais indicado; não houve influência do vigor sobre a produção no campo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGodoy, RodolfoAbrahão, Jairo Teixeira Mendes2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16807Pesquisa Agropecuaria Brasileira; v.13, n.3, mar. 1978; 83-92Pesquisa Agropecuária Brasileira; v.13, n.3, mar. 1978; 83-921678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16807/11140info:eu-repo/semantics/openAccess2014-04-15T19:18:16Zoai:ojs.seer.sct.embrapa.br:article/16807Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:18:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
