A busca de diminuição de custos de implantação de lavouras de trigo, vem levando os produtores utilizarem sementes salvas, as quais muitas vezes com qualidade física e fisiológica desconhecidas. Visando conhecer as características das sementes utilizadas na implantação de cultivos, o trabalho objetivou comparar componentes físicos e fisiológicos de sementes salvas de trigo produzidas por produtores familiares dos municípios de Planalto, Pérola D´Oeste e Pranchita, no Sudoeste do Paraná em relação às sementes comerciais. As sementes foram coletadas em propriedades que guardaram sementes da safra 2015/2016 para diminuição de custos na implantação do cultivo na safra 2016/2017. A análise das sementes foi realizada no Laboratório de Análise de Sementes da UTFPR-DV. Foram realizados testes de pureza, peso hectolítrico, umidade e peso de mil sementes para avaliar os componentes físicos. Teste de germinação, condutividade elétrica e teste a frio para os componentes fisiológicos. Os dados obtidos foram analisados através da análise de variância, e as médias comparadas pelo teste de Tukey. As sementes salvas apresentaram resultados semelhantes para os componentes físicos. Os lotes comerciais apresentaram menor quantidade de sementes mortas para as duas cultivares avaliadas. As sementes salvas apresentaram valores discrepantes para condutividade elétrica em relação às comerciais. Para as cultivares objeto do presente estudo, os testes aplicados não apontaram diferenças significativas na qualidade das sementes com relação à sua origem. 2020-11-13T11:26:35Z 2020-11-13T11:26:35Z 2017-11-20 bachelorThesis PIVA, Andre Luiz.
