Resumo: Experiments were installed at four localities in soils of low fertility of "cerrado" recently recuperated, to explore the possibility to produce seed of good quality. Three cultivars (Santa Rosa, IAC-1 and IAC-2) and three populations (250.000, 333,000 and 500,000 plants per hectare) were utilized for this purpose. During the storage period laboratory tests were made every two months to evaluate on the germination. The vigor, the weight of 100 seeds, and its moisture content were also measured. Analysing each parameter separately, IAC-1 weighed more than Santa Rosa, and IAC.2 whereas the latter two showed greater germination and vigor. Among populations under study 250.000 plants per hectare was the best treatment for seed weight and there was very little difference among population for germination and vigor of seed. Among localities, the weight of seeds was similar at São Simão, Bento Quirino and Mococa whereas at Aguaí the seed quality was better.

Foram testadas populações de 250.000, 333.000 e 500.000 plantas por hectare com as cultivares Santa Rosa, IAC-1 e IAC-2. Determinou-se inicialmente o teor de umidade, índice de vigor e peso de 100 sementes. Durante o armazenamento, efetuaram-se testes periódicos para verificar a germinação das sementes, e, por ocasião do teste final, determinou- se novamente o teor de umidade. Analisando-se cada parâmetro independentemente, os resultados mostraram que IAC-1 foi a cultivar que apresentou pesos de sementes mais elevados, enquanto que 'Santa Rosa' e 'IAC-2' produziram sementes de melhor germinação e vigor. Analisando o espaçamento, verificou-se que, no espaçamento maior (250.000 plantas/ha), as sementes apresentaram maior peso, enquanto que, em relação a germinação e vigor, as diferenças foram pequenas. As localidades de São Simão, Bento Quirino e Mococa, sem diferirem entre si, forneceram sementes de pesos superiores às de Aguaí, enquanto que esta localidade proporcionou sementes de vigor e valor germinativo superiores às demais.  Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMaeda, Jocely AndreuccettiMascarenhas, Hipólito A.A.Almeida, Luiz D’Artagnan deNagai, Violeta2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15286Pesquisa Agropecuaria Brasileira; v.18, n.5, maio 1983; 515-518Pesquisa Agropecuária Brasileira; v.18, n.5, maio 1983; 515-5181678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15286/9116info:eu-repo/semantics/openAccess2014-04-16T18:55:13Zoai:ojs.seer.sct.embrapa.br:article/15286Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:55:13Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
