Resumo: dc.description.abstractThis work aimed to analyze the sanitary quality of stored corn grains, through the "Blottertest" and use of the water restriction technique. The experiment was carried out using a completely randomized design (D.I.C.) with 10 treatments and 24 repetitions, in which each repetition consisted of a Petri dish with 8 seeds/plate. The treatments were submitted to NaCl and KCl solution at restriction levels (-0.6; -0.7; -0.8 and -0.9 Mpa), freezing and control. The seeds were distributed in plastic Petri dishes (a total of eight/plate), measuring 90x15mm in diameter, containing three layers of filter paper soaked in the aforementioned solutions. These remained at a temperature of 25°C±2, for a period of 7 days, and were later analyzed for percentage of germination, radicle length and associated fungi, under a stereoscopic and optical microscope. The incidence of the fungal genera Colletotrichum sp., Aspergillus sp., Penicillium sp., Rhyzopus sp., Cladosporium sp., Bipolaris sp., Curvularia sp. and Fusarium sp. The genera with the highest incidence were Colletotrichum sp. (88.6%), Penicillium sp. (4.7%) and Aspergillus sp. (2.5%). The control treatment had the lowest average incidence rate in relation to the water restriction treatment. The lowest percentage of germination (1%) was obtained in the freezing treatment, which provided 9.5% of incidence of fungal genera. The greatest diversity of fungi was observed in the NaCL and KCl treatments (-0.9 Mpa), the same treatments provided the greatest inhibition of germination and radicle emission.pt_BR
