Resumo: The objective of this work was to analyze structurally the pods and seed coats of soybean (Glycine max) cultivars, as well as to determine the quality of seeds when subjected to deterioration by weathering in pre-harvest. A 7×3 factorial arrangement was used – seven cultivars and three volumes of simulated rainfall (0, 54, and 162 mm). Exposure to rainfall was simulated in the R8 phenological stage. Then, the plants were taken to a greenhouse, where they were kept until the time of collection of pods and seeds. After collection, the following evaluations were carried out: tetrazolium test, lignin content in pods and seed coats, and structural analysis of pods (exocarp, mesocarp, and endocarp thickness) and seed coats (epidermis, hypodermis, and parenchymal-cell thickness). Pre-harvest rainfall of 54 and 162 mm reduces the quality of soybean seeds; however, the response to deterioration by weathering differs according to the cultivar. The tolerance to all simulated rainfall was greater for BRSMT Pintado, BRS Jiripoca, and M8210IPRO and lower for BRS 1010IPRO. Pods with a greater thickness of the exocarp, mesocarp, and endocarp and a high lignin content show greater resistance to weathering deterioration and seeds with greater vigor and viability. The thickness of the hypodermis of the testa is related to resistance to weathering deterioration and to the obtainment of high-quality seeds.

Utilizou-se arranjo fatorial 7×3 – sete cultivares e três volumes de precipitações pluviais simuladas (0, 54 e 162 mm). A exposição à chuva foi simulada no estádio fenológico R8. Em seguida, as plantas foram levadas à casa de vegetação, onde foram mantidas até a coleta das vagens e das sementes. Após a coleta, realizaram-se as seguintes avaliações: teste de tetrazólio, teor de lignina nas vagens e nos tegumentos, e análise estrutural de vagens (espessura do exocarpo, do mesocarpo e do endocarpo) e tegumentos (espessura da epiderme, da hipoderme e das células parenquimatosas). Precipitações de 54 e 162 mm em pré-colheita reduzem a qualidade das sementes de soja; entretanto, a resposta à deterioração por umidade difere de acordo com a cultivar. A tolerância a todas as precipitações pluviais simuladas foi maior para BRSMT Pintado, BRS Jiripoca e M8210IPRO e menor para BRS 1010IPRO. Vagens com maior espessura do exocarpo, do mesocarpo e do endocarpo e elevados teores de lignina apresentam maior tolerância à deterioração por umidade e sementes com maior vigor e viabilidade. A espessura da hipoderme da testa de tegumentos está relacionada à tolerância à deterioração por umidade e à obtenção de sementes de elevada qualidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUniversidade Estadual de LondrinaEmbrapa SojaCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUniversidade Estadual de LondrinaEmbrapa SojaBrzezinski, Cristian RafaelAbati, JuliaZucareli, ClaudemirMedri, CristianoMertz-Henning, Liliane MarciaKrzyzanowski, Francisco CarlosFrança-Neto, José de BarrosHenning, Fernando Augusto2022-05-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/27052Pesquisa Agropecuaria Brasileira; V.57, Jan./Dec., 2022: Publicação contínua em volume anual; e02697Pesquisa Agropecuária Brasileira; V.57, Jan./Dec., 2022: Publicação contínua em volume anual; e026971678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/27052/15000Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2023-01-23T13:40:23Zoai:ojs.seer.sct.embrapa.br:article/27052Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2023-01-23T13:40:23Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
