Resumo: | The use of an appropriate method that accurately expresses physiological seed quality and minimizes possible phytotoxicity by chemical products in laboratory testing with soybean seeds is relevant. The objective of this work was to evaluate the influence and infer the method adequacy for the representative evaluation of physiological quality of soybean seeds treated with phytosanitary products. Two experiments were carried out in a completely randomized design, with trial 1 in a 9×5 factorial scheme involving nine seed treatments, including fungicides and insecticides, and solutions with five osmotic potentials (0, -0.25, -0.5, -0.75 and -1.0 MPa) for wetting a paper substrate in a germination experiment, with evaluation of the normal seedlings at five and eight days after sowing. The second experiment consisted of a 9×7 factorial, with nine seed treatments and seven methods for germination evaluation at 5 days (between paper - BP, between sand - BS, between paper with water restriction - BPWR, between paper with preconditioning - BPC, sand between paper - SBP and vermiculite between paper - VBP). Treatments with insecticides affect seedling germination and evaluation, with greater phytotoxicity in relation to fungicides. Methods with readily available water led to greater phytotoxicity than methods with low water availability. For soybean germination evaluation of seeds treated with phytosanitary products, the BPC, SBP and VBP methods were optimal. |

O objetivo no trabalho foi avaliar a influência e inferir sobre a adequação de metodologias para a representativa avaliação da qualidade fisiológica de sementes de soja tratadas com produtos fitossanitários. Realizou-se dois experimentos em delineamento inteiramente casualizado, sendo o experimento um em esquema fatorial 9x5, envolvendo nove tratamentos de sementes, entre fungicidas e inseticidas, e cinco potenciais osmóticos (0, -0,25; -0,5; -0,75 e -1,0 MPa) na solução para molhamento do substrato papel no experimento de germinação, com avaliação das plântulas normais aos cinco e oito dias. O 2° experimento foi constituído por fatorial 9x7, com nove tratamentos de sementes e sete metodologias para avaliação da germinação aos cinco dias (entre papel - EP, entre areia - EA, entre papel com restrição hídrica - EPR, entre papel com pré-condicionamento - EPC, areia entre papel - AEP e vermiculita entre papel - VEP). Os tratamentos com moléculas inseticidas afetam a germinação e avaliação das plântulas, com maior fitotoxidez em relação à fungicidas. Metodologias com água prontamente disponível, ocasionam maior fitotoxidez. Para avaliação de germinação de soja tratadas com produtos fitossanitários as metodologias EPC, AEP e VEP são as mais apropriadas.Editora da Universidade Federal de Lavras2020-08-21T16:38:29Z2020-08-21T16:38:29Z2020info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfROCHA, D.
