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.
