“…Nesta etapa, alguns cuidados devem ser tomados com o objetivo de prevenir principalmente injúrias mecânicas e potencializar o desempenho fisiológico do lote de sementes por meio da utilização mesa de gravidade (LOPES et al, 2011;SILVA et al, 2011).…”

“…However, Silva et al (2011), in working with four soybean cultivars, observed decreased seed vigor after beginning processing in one of the cultivars but not in the others. Thus, is possible to observe that seeds of different species have a characteristic behavior during processing stages when considering the first germination count variable.…”

“…Paiva et al (2000), also working with maize seeds, observed that processing did not affect seed germination, and Silva et al (2011) did not observe an influence of the processing stages on the seed vigor of four soybean cultivars when using an accelerated aging test. The results of both of these groups corroborate the results obtained in this study.…”

“…Seed processing comprises a set of operations that begin with the receipt of the material at the processing unit and then proceed through later stages such as shelling, drying, threshing, grading and finishing with bagging and subsequent distribution. This last stage constitutes an essential step in producing high-quality seeds and must be performed appropriately; otherwise, the previous efforts in developing the material and using appropriate culture techniques are wasted (Fessel et al, 2003;Silva et al, 2011). Compared to other crops, maize processing is highly specialized from an operational standpoint; grading is required due to significant variations in the size, shape and quality of the seeds, depending on their position on the cob (Ferreira and Sá, 2010).…”

Seeds are the primary input in the maize production process, and monitoring seeds through the processing stages is an essential practice in the production chain, particularly when identifying critical points in the process that can interfere with the final seed quality. Therefore, the objective of this study was to evaluate the effect of processing stages in the physiological quality of Balu 761 maize hybrid seeds. Seeds from the Balu 761 maize hybrid obtained during processing (receipt, shelling, drying, threshing, grading and bagging) were used. The experimental design was completely randomized with four replications. Physiological seed quality was evaluated using germination, accelerated aging, cold testing, electrical conductivity and seedling length tests, with the latter used to determine the length and dry weight of the shoot and root. The data were subjected to a variance analysis, and the means were compared using the Scott-Knott test (p≤0.05). The physiological quality of Balu 761 maize hybrid seeds was enhanced during processing because the percentage of normal seedlings from cold test, as well as the root length, shoot length and shoot dry weight were optimized when considering the process as a whole, which contributed to the increased vigor of both seeds and seedlings. The germination and accelerated aging tests were not influenced by the processing stages.

“…Factors such as water content and genetic variability cause large influences on the susceptibility of the seeds to mechanical damages (Silva et al, 2011b). In many cases, these damages are not sufficient to destroy the structures of the seeds, but cause the appearance of cracks that lead to abnormalities in the seedlings, higher susceptibility to the action of microorganisms and higher sensitivity to chemical treatments, thus reducing the quality and storage potential of the lots.…”

A B S T R A C TThis study aimed to evaluate the quality of soybean seeds with high level of mechanical damages from different processing stages and stored with and without fungicide treatment. Collections of seed samples were performed during the processing at the following points: hopper, pre-cleaning, dryer, cleaning, spiral, sieve-classifier and the gravity table. The experimental design was completely randomized in a 9 x 2 factorial scheme, with 9 collection points and two seed treatments, in four replicates. The seeds were then evaluated immediately after processing and after six months of storage. The processing progressively improved the attributes of soybean seed quality throughout the different stages in which the gravity table plays an important role in the improvement of the physiological and sanitary quality of the lot, favoring the storage potential and vigor of the seeds. The treatment of the seeds with fungicides is effective in controlling fungi before and after storage. The storage of soybean seeds with high level of mechanical damage markedly increases their deterioration.Qualidade de sementes de soja com alto índice de danos mecânicos após beneficiamento e armazenamento R E S U M O Objetivou-se, neste trabalho, avaliar a qualidade de sementes de soja com elevado índice de danos mecânicos, provenientes de diferentes etapas do beneficiamento e armazenadas com e sem tratamento com fungicida. Foram efetuadas, ao longo do beneficiamento, coletas de amostras de sementes, nos seguintes pontos: moega, prélimpeza, secador, limpeza, espiral, classificador-peneira e densimétrica. O delineamento experimental adotado foi inteiramente casualizado, em esquema fatorial 9 x 2, sendo 9 pontos de coleta e dois tratamentos de sementes, em quatro repetições. As sementes foram avaliadas logo após o beneficiamento e aos seis meses de armazenamento. O beneficiamento melhora os atributos da qualidade de sementes de soja ao longo das diferentes etapas em que a máquina densimétrica desempenha papel importante no aprimoramento da qualidade fisiológica e sanitária do lote favorecendo o vigor das sementes. O tratamento das sementes com fungicidas carbendazim + thiram é eficiente no controle dos fungos de Cladosporium sp., Fusarium sp., Penicillium sp. e Aspergilus sp. antes e depois do armazenamento. O armazenamento de sementes de soja, com elevado índice de danos mecânicos, aumenta acentuadamente sua deterioração.
