No. of bitstreams: 1 dissertacao_joao_rodolfo_nunes.pdf: 261220 bytes, checksum: f94a6973f7a6e6ef02e08536a166c9c0 (MD5) Previous issue date: 2008-06-06 / This paper had the objective of checking the effects of three different sequence of conditioning on the qualities of seeds from silage sorghum (Sorghum bicolor L.) and to such deed, it was used FEPAGRO-RS 11, FEPAGRO-RS 12, FEPAGRO 17 e FEPAGRO 18. The treatment followed the next sequence: T1- pre cleaning; T2 pre cleaning plus three passages through cleaning; T3 pre cleaning, polishing and cleaning. The pre cleaning procedure was done by a pre-cleaning machine with a 5,0mm diameter sieve. The clean was done with an air machine and sieves, whose round holes measured 3,2 and 2,8mms. The polishing was performed by a cereal polisher machine from the brand Grimm (6 to 10sc/h). The treatments were measured through the levels of moisture, the mass of thousand seeds, purity physical analysis and germination tests, first germination count, accelerated aging, electric conductivity and tetrazolien, applied right after the conditioning and 12 months later. It as observed some differences between FEPAGRO-RS 11, FEPAGRO-RS 12, FEPAGRO 17 e FEPAGRO 18, concerning the levels of initial moisture, the mass of thousand seeds and the physiological qualities of the seeds. All the conducting treatments managed to obtain a purity quality superior to 99,0% It can be concluded that the sequence of conditioning consisted by the pre cleaning operations, polishing and cleaning, improves the visual aspect and does not damage the physiological potential of the seeds from silage sorghum. / O presente trabalho teve por objetivo verificar o efeito de três seqüências de beneficiamento sobre a qualidade de lotes de sementes de sorgo silageiro (Sorghum bicolor L.) e, para tal, utilizaram-se os cultivares FEPAGRO-RS 11, FEPAGRO-RS 12, FEPAGRO 17 e FEPAGRO 18. Os tratamentos consistiram das seguintes seqüências: T1 apenas a pré-limpeza; T2 pré-limpeza mais três passagens pela limpeza; T3 pré-limpeza, polimento e limpeza. A operação de pré-limpeza foi realizada com máquina de ar e peneiras, contendo uma peneira com orifício de 5,0mm de diâmetro. A limpeza foi efetuada na mesma máquina de ar e peneiras, cujas peneiras tinham orifícios redondos de 3,2 e 2,8mm. O polimento foi realizado com um polidor de cereais da marca Grimm (6 a 10sc/h). Os tratamentos foram avaliados através das determinações do grau de umidade, massa de mil sementes e 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. Observaram-se diferenças entre os cultivares, quanto ao grau de umidade inicial, massa de mil sementes e qualidade fisiológica das sementes. Todos os tratamentos de beneficiamento permitiram obter pureza física superior a 99,0%. Concluiu-se que a seqüência de beneficiamento composta pelas operações de pré-limpeza, polimento e limpeza melhora o aspecto visual e não prejudica o potencial fisiológico das sementes de sorgo silageiro.
