Resumo: | Maize inbred lines, due to their high level of homozygosity, have different behaviors from commercial hybrids in relation to herbicide sensitivity. Tembotrione, a post-emergence herbicide, widely used in the production of commercial corn hybrids, has been reported as causing phytotoxic effects. In this context, the objective of this work was to evaluate the phytotoxic potential of tembotrione, applied to six maize lines, assessing its effects over morphological and production aspects, with emphasis on photosynthesis. For this, an experiment was implemented in the municipality of Goianésia, in the brazilian Cerrado, during the dry season, using conventional sprinkler irrigation. The experimental design was randomized blocks, arranged in split plots with two factors: six maize inbred lines by four doses of tembotrione (0; 120; 240; and 480 mL ha-1). It was verified that there were no visual symptoms of toxicity in the genotype 43NG34381L with the application of 480 mL ha-1, even though it corresponded to twice that recommended in the label, being the inbred line more tolerant to the herbicide. The genotypes Z9999L, G55081L and 551CB, although sensitive to tembotrione at the label dose (240 mL ha-1), had moderate phytotoxicity at 7 days after application (DAA), without any symptoms at 14 and 21 DAA. The genotypes ZKQMR2357L and PGAG10051L were the most sensitive to the application of the herbicide tembotrione and maintained persistent symptoms of toxicity over time, even with the application of 240 mL ha-1. The yield of the ZKQMR2357L line was negatively affected by the toxicity caused by the herbicide. |

La tembotriona, un herbicida de post-emergencia, ampliamente utilizado en la producción de híbridos comerciales de maíz, ha sido reportado como causante de efectos fitotóxicos. En este contexto, el objetivo de este trabajo fue evaluar el potencial fitotóxico de la tembotriona, aplicada a seis líneas de maíz, profundizando sus efectos sobre aspectos morfológicos y productivos, con énfasis sobre la fotosíntesis. Así se implementó un experimento en el municipio de Goianésia, región de cerrado de Goiás, Brasil, en el período seco del año, utilizando riego por aspersión convencional. El diseño experimental fue bloques al azar, dispuestos en parcelas divididas con dos factores: seis líneas de maíz por cuatro dosis del herbicida tembotriona (0; 120; 240; y 480 mL ha-1). Se encontró que no hubo síntomas visuales de toxicidad en la línea 43NG34381L con la aplicación de 480 mL ha-1, a pesar de que correspondió al doble de lo que es recomendado en el prospecto, siendo la cepa más tolerante al herbicida. Las líneas Z9999L, G55081L y 551CB, aunque sensibles a la tembotriona a la dosis recomendada (240 mL ha-1), presentaron fitotoxicidad moderada a los 7 días después de la aplicación (DDA), sin síntomas a los 14 y 21 DDA. Las líneas ZKQMR2357L y PGAG10051L fueron las más sensibles a la aplicación del herbicida tembotriona y mantuvieron síntomas persistentes de toxicidad al largo del tiempo, incluso con la aplicación de 240 mL ha-1. El rendimiento de la línea ZKQMR2357L fue afectado negativamente por la toxicidad provocada por el herbicida.As linhagens de milho, pelo seu elevado nível de homozigose, possuem comportamentos diferentes dos híbridos comerciais em relação à sensibilidade a herbicidas. O tembotrione, herbicida de pós-emergência, amplamente utilizado em campo de produção de híbridos comerciais de milho-doce, tem sido relatado como causador de efeitos fitotóxicos. Nesse contexto, o objetivo deste trabalho foi avaliar o potencial fitotóxico do tembotrione, sobre seis linhagens de milho, aprofundando seus efeitos sobre aspectos morfológicos e de produção, com ênfase sobre o processo fotossintético. Para isso, um experimento foi implantado no município de Goianésia, região do Cerrado goiano, Brasil, no período seco do ano, utilizando-se de irrigação por aspersão convencional. O delineamento experimental foi blocos casualizados, disposto em parcelas subdivididas com dois fatores: seis linhagens de milho por quatro doses de tembotrione (0; 120; 240; e 480 mL ha-1). Verificou-se que não houve sintoma visual de toxicidade no genótipo 43NG34381L com a aplicação de 480 mL ha-1, mesmo sendo correspondente ao dobro daquela recomendada em bula, sendo a linhagem mais tolerante ao herbicida. As linhagens Z9999L, G55081L e 551CB, embora sensíveis ao tembotrione na dose de bula (240 mL ha-1), tiveram fitotoxidade moderada aos 7 dias após aplicação (DAA), sem nenhum sintoma aos 14 e 21 DAA. As linhagens ZKQMR2357L e PGAG10051L foram as mais sensíveis a aplicação do herbicida tembotrione e mantiveram sintomas de toxidez persistentes ao longo do tempo, mesmo com a aplicação de 240 mL ha-1. A produtividade da linhagem ZKQMR2357L foi negativamente afetada pela toxicidade provocada pelo herbicida.Research, Society and Development2022-08-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3264710.33448/rsd-v11i10.32647Research, Society and Development; Vol. 11 No. 10; e571111032647Research, Society and Development; Vol. 11 Núm. 10; e571111032647Research, Society and Development; v. 11 n. 10; e5711110326472525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/32647/28093Copyright (c) 2022 Eliel Matheus Sousa; Hyrandir Cabral de Melo; Frederico Rocha Rodrigues Alves; Aniela Pilar Campos de Melo; Dalva Graciano Ribeiro; Cleiton Mateus Sousahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSousa, Eliel MatheusMelo, Hyrandir Cabral deAlves, Frederico Rocha RodriguesMelo, Aniela Pilar Campos de Ribeiro, Dalva GracianoSousa, Cleiton Mateus2022-08-12T22:23:03Zoai:ojs.pkp.sfu.ca:article/32647Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:48:34.687822Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
