Previous issue date: 2016-06-03 / Para oferecer aos agricultores sementes de soja com qualidade e na quantidade
demandada, as empresas sementeiras devem implementar eficientes processos de
controle interno de qualidade, visando aferir a constantemente a germinação e o
vigor das sementes. A presente pesquisa teve como objetivo averiguar o processo
de controle de qualidade interno na Sementes São Francisco Rio Verde, Goiás. O
trabalho foi realizado em laboratório de empresa sementeira na cidade de Rio Verde
- GO. Foram utilizados 272 lotes de sementes de soja da cultivar NA 5909 RG,
categoria S1, da safra 2014/2015. Os testes avaliados foram: tetrazólio précondicionado
por 16 horas, envelhecimento acelerado por 72 horas, teste de
germinação, teste de solo e emergência em areia. Os resultados demonstraram que
os testes de envelhecimento acelerado e tetrazólio são confiáveis no controle de
qualidade de lotes de soja. Conclui-se que os lotes apresentaram vigor e viabilidade
satisfatórios, porém, o teste de germinação 180 dias após a colheita, demonstrou
queda da viabilidade. / To provide soybean farmers with quality and quantity demanded, the seed
companies should implement efficient internal quality control processes to assess the
constantly germination and seed vigor. This study aimed to verify the internal quality
control process in soybean seed company, in Rio Verde, Goiás. The essay was
carried out in laboratory of a seed company in the Rio Verde-GO city. Were used 271
soybean seeds lots of the cultivar IN 5909 RG, category S1 cultivated in the
agricultural year of 2014/2015. The tests evaluated were tetrazolium test with
preconditioned for 16 hours, accelerated aging test for 72 hours, standard
germination test, soil test and emergence in sand. The results showed that the
accelerated aging test and tetrazolium test are reliable for use in intern quality control
of soybean seeds lots. It has concluded that the lots had satisfactory vigor and
viability, however, the germination test 180 days after harvested decreased in
viability.
