Avaliação da qualidade de grãos de soja armazenados em silo vertical de bancada

Abstract

The soybeans (Glycine max (L.) Merrill) is the grain more produced in the world, and like the other grains require a control of temperature and of relative humidity of the air while stored for what the quality of grains be preserved until reaching the consumer. The influence these abiotic factors can result on the loss of quality and even in the total deterioration of the grain, due to fungal attack and insect-pest storage. This work had as objective evaluate the physical, physiological and sanitary quality of stored soybeans in a vertical bench silo, in ambient conditions of temperature and relative humidity. One 20 kg of soybeans sample was stored for 3 months, being that every 22 days were realized germination, electrical conductivity, water content, sanity and infestation tests to can analyze the influence of the temperature and ambient relative humidity. After the tests and statistical analysis, it was found that the temperature and relative humidity of the air influenced in a negative way in a grains’ quality throughout the 3 months, because there was reduction in germination percentage, increase in electrical conductivity, besides a variation in the water content becoming the grain propitious to fungal attack.
