Resumo: | The use of high doses of glyphosate, even if tolerant (RR) technology, can cause leaf insults, such as the yellow flashing effect, which is characterized by a yellowing of the leaves, which can lead to loss of productivity. The present study aimed to increase doses of glyphosate in tolerant soybean. Tests were conducted in greenhouse 2015/2016 and 2016/2017, in Palotina, western region of Paraná in a completely randomized arrangement. The first assay was conducted in a 3x8 factorial set (products x cultivars) with four replicates mixed with glyphosate with growth regulator, one compound of amino acids and one source of manganese, and in the second a factorial scheme 6x3 (products x cultivars) using glyphosate, a growth regulator, a source of manganese and the glyphosate associated to the other products, besides a control without application. A phytotoxicity, chlorophyll index, shoot dry mass and root mass were evaluated visually. A variation of response to cultivar was observed due to characteristics of each genotype. The differences between the products were not observed. A cultivar ‘M6210’ presented greater symptom of phytointoxication while cultivating ‘BMX Ponta’, presenting greater tolerance. No phytotoxic effect was observed for the test. |

O presente estudo objetivou avaliar técnicas visando a atenuação do efeito de doses de glyphosate em cultivares tolerantes de soja (RR e RR2). Os ensaios foram conduzidos em estufa nos anos 2015/2016 e 2016/2017, em Palotina, região oeste do Paraná em um arranjo inteiramente casualizado. O primeiro ensaio foi conduzido em arranjo fatorial 3x8 (produtos x cultivares) com quatro repetições utilizando misturas de glyphosate com regulador de crescimento, um composto de aminoácidos e uma fonte de manganês, e no segundo um esquema fatorial 6x3 (produtos x cultivares) utilizando glyphosate, um regulador de crescimento, uma fonte de manganês isolados e o glyphosate associado aos demais produtos, além de um tratamento controle sem aplicação. Foram avaliados visualmente a fitotoxicidade, índice de clorofila, massa seca de parte aérea e de raiz. Observou-se uma diferença de resposta para as cultivares devido a características de cada genótipo. Não foram observadas diferenças entre os produtos. A cultivar ‘M6210’ apresentou-se maior sintoma de fitointoxicação enquanto a cultivar ‘BMX Ponta’ apresentou maior tolerância. Para o segundo ensaio não foi observado efeito fitotóxico.Sociedade de Ciências Agrárias de Portugal2020-01-29T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/rca.18326eng2183-041X0871-018XBaccin, Luisa CarolinaKrenchinski, Fábio HenriqueAlbrecht, Leandro Paiolada Cruz, Gabriela GayosoAlbrecht, Alfredo Júnior PaiolaMattiuzzi, Mateus DaupubelPertuzati, Alineinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-06T09:25:19Zoai:ojs.revistas.rcaap.pt:article/18326Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:31:20.781183Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
