Resumo: | The soybean seeds produced in Santa Catarina have the potential for the application of new marketing strategies because they have superior quality over the minimum standards established by the Brazilian legislation. This potential was verified using time series analysis (TS). The main goal of this study was to characterize the physiological quality of soybean seeds produced in the State of Santa Catarina using data from the last five harvests in order to establish new commercialization strategies based on seed quality. Historical data for germination and vigor were obtained from the 2012/2013 to 2016/2017 harvests, with a total of 4606 lots studied. To validate the historical data, data from the 2016/2017 harvest were included. For this analysis, 100 lots of soybean seeds from the 2016/2017 harvest were collected, and laboratory tests for germination and vigor were performed. The results of the time series analysis showed that, on average, the germination rate ranged from 89 to 93%, with all values being higher than the minimum required for commercialization by the Brazilian legislation. Vigor ranged on average from 82 to 90%. Currently, there is no reference value for vigor in the Brazilian legislation for seed commercialization purposes. Of the total of lots evaluated, 1%, 2%, 21%, and 76% of seeds presented germination < 70%, 70–80%, 80–90%, and > 90%, respectively, whereas 4%, 3%, 7%, 17%, and 69% of the lots presented vigor < 70%, 70–75%, 75–80%, 80–85%, and > 85%, respectively. Considering that 76% of the lots presented germination > 90% and 69% of the lots had vigor > 85%, the lots that presented these percentages were ranked, and 64% were determined to meet high quality standards. Taking into account the 100 sampled lots from the 2016/2017 harvest, 55% presented germination > 90% and 58% had vigor > 85%. In this harvest, 41% of the lots met the standards of at least 90% germination and 85% vigor according to the ranking methodology. This study concludes that due to the stability of climatic conditions, the State of Santa Catarina produces soybean seeds with physiological quality above the minimum standards, which allow the establishment of a minimum vigor standard of 85% for the commercialization of soybean seeds. |

A comprovação deste potencial é possível através do uso de análises de séries temporais. Com isso, o objetivo deste estudo foi caracterizar uma qualidade fisiológica de sementes de soja produzida no estado de Santa Catarina nas últimas 5 safras, buscando obter novas estratégias de comercialização com base na qualidade das sementes. Os resultados históricos dos percentuais de germinação e vigor de sementes de soja foram registrados nas safras 2012/2013 a 2016/2017, totalizando 4606 lotes. Para validação desses dados, na safra 2016/2017, foram coletadas 100 sementes de soja e conduzidas ou teste de germinação e vigor no laboratório de análise de sementes. Os dados do histórico foram usados para análise estatística usando séries temporais e regressão. Ao conjunto de dados foram incluídos os 100 lotes analisados no safra 2016/2017 e ranqueados nas classes de germinação e vigor. O percentual de germinação e vigor dos lotes mantidos é superior a 90% e 87%, respectivamente, com redução de 0,32% na germinação e 0,80% para vigor ao longo das cinco safras analisadas, evidenciando que há manutenção da qualidade das sementes ao longo das safras. A manutenção está atrelada a fatores climáticos favoráveis à produção e armazenamento de sementes de soja observadas em Santa Catarina. Do total de lotes analisados (4606) a cinco safras, 3.500 lotes (76%) apresentaram germinação superior a 90% e 3.178 lotes (69%) vigor superior a 85%. Dos 100 lotes analisados na safra 2016/2017, 55 relataram germinação acima de 90% e 58 de vigor superior a 85%. Os resultados obtidos na safra 2016/2017 validam uma série histórica e comprovam a alta qualidade fisiológica das sementes de soja produzidas em Santa Catarina. O estudo permite concluir que a função de estabilidade das condições climáticas no estado de Santa Catarina produz sementes de soja com qualidade fisiológica acima dos padrões permitidos, ou que permite definir um padrão mínimo de vigor de 85% para a comercialização de sementes de soja.UEL2020-01-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Históricaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3609210.5433/1679-0359.2020v41n1p49Semina: Ciências Agrárias; Vol. 41 No. 1 (2020); 49-60Semina: Ciências Agrárias; v. 41 n. 1 (2020); 49-601679-03591676-546Xreponame:Semina.
