Resumo: The objective of this paper was to check the effects of three different sequences of conditioning on seeds quality of silage sorghum (Sorghum bicolor L.), cultivars FEPAGRO-RS 11, FEPAGRO-RS 12, FEPAGRO 17 e FEPAGRO 18. Treatments followed the next sequence: S1- pre cleaning; S2 - pre cleaning plus three passages through cleaning; S3 - pre cleaning, polishing and cleaning. Treatments were measured through the levels of moisture, the mass of thousand seeds, purity analysis and tests of germination, first germination count, accelerated aging, electric conductivity and tetrazoliun, applied right after conditioning and 12 months later. It was observed some differences between cultivars, concerning levels of initial moisture, mass of thousand seeds and physiological quality of seeds. All the conducting treatments managed obtained purity quality superior to 99,0%. Sequences of conditioning consisted by pre cleaning operations, polishing and cleaning, improves visual aspect and does not damage physiological quality of the seeds from silage sorghum, but three cleaning operations and polishing affect seed vigour after storage of one year.

As seqüências de beneficiamento foram: S1 - apenas a pré-limpeza; S2 - pré-limpeza mais três passagens pela limpeza; S3 - pré-limpeza, polimento e limpeza. Os tratamentos foram avaliados através das determinações do grau de umidade, massa de mil sementes, análise de pureza e dos testes de germinação, primeira contagem da germinação, envelhecimento acelerado, condutividade elétrica e tetrazólio, aplicados logo após o beneficiamento e 12 meses depois. Houve diferenças entre os lotes dos cultivares, quanto ao grau de umidade inicial, massa de mil sementes e qualidade fisiológica das sementes. Todas as seqüências de beneficiamento obtiveram pureza física superior a 99,0%. A seqüência de beneficiamento composta pelas operações de pré-limpeza, de polimento e de limpeza melhora o aspecto visual e não prejudica a qualidade fisiológica das sementes de sorgo silageiro, porém três passagens pela limpeza e polimento afetam o vigor das sementes após um ano de armazenamento. Departamento de Diagnóstico e Pesquisa Agropecuária.
