Resumo: This work was carried out at the Fazenda Experimental Lageado, at Botucatu, SP, to evaluate the physiological quality of cucumber (Cucumis sativus L.), seeds harvested at different fruit maturity stages and post-harvest resting periods. Fruits of cultivar Pérola were harvested at 6 ages (20, 25, 30, 35, 40 and 45 days after anthesis) and they were stored at room temperature for 0, 5, 10 or 15 days before seed extraction. After this, seeds were fermented for 2 days, washed and dried. External visual characteristics of fruits and seeds were observed at harvest. Seed quality was evaluated as for moisture, dry matter content, dimensions, germination, and vigour. Results showed that seed germination and vigour increased in fruits aging from 20 to 40 days. Post-harvest periods improved seed quality of 20-day old fruits not reaching the seed quality levels observed in 40 or 45-day old fruits, without post-harvest resting period. Seeds from fruits at 25, 30 and 35 days of age, with 10 or 15 days of post-harvest resting period reached the same quality levels of seeds from fruits with 40-45 days old.

Colheram-se frutos com 25, 30, 35, 40 e 45 dias de idade após a antese, em uma cultura realizada em Botucatu, SP. Os frutos colhidos foram armazenados por períodos de 0, 5, 10 e 15 dias, para então proceder-se a extração das sementes e a sua fermentação natural por dois dias sob temperatura ambiente. Avaliou-se peso, diâmetro e comprimento de frutos e conteúdo de matéria seca, teor de água, dimensões, germinação e vigor de sementes. Realizou-se, também, o acompanhamento das características visuais de frutos e sementes. Pelos resultados obtidos concluiu-se que os valores de germinação e vigor das sementes foram crescentes dos 20 aos 40 dias de idade dos frutos. O repouso pós-colheita melhorou a qualidade fisiológica das sementes de frutos com a menor idade (20 dias), porém sem atingir a qualidade de sementes de frutos com 40 e 45 dias sem repouso. Já no tocante a frutos com 25, 30 e 35 dias de idade, o repouso pós-colheita (10 a 15 dias) melhorou a qualidade das sementes, chegando a atingir valores de germinação e vigor tão elevados quanto os de sementes oriundas de frutos com 40 e 45 dias.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBarbedo, Claudio JoséNakagawa, JoãoBarbedo, Adeliana Saes CoelhoZanin, Antonio Celso Wagner1997-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4735Pesquisa Agropecuaria Brasileira; v.32, n.9, set. 1997; 905-913Pesquisa Agropecuária Brasileira; v.32, n.9, set. 1997; 905-9131678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4735/7299info:eu-repo/semantics/openAccess2015-03-18T18:34:54Zoai:ojs.seer.sct.embrapa.br:article/4735Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-03-18T18:34:54Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
