Resumo: | Trinexapac-ethyl reduces lodging in white oat, but its use in seed production fields requires knowledge of its impact on the expression of descriptors, under penalty of compromising the identification of cultivars. In this work, six white oat cultivars of different stature classes (Low: Brisasul and URS Taura; Medium: IPR Artemis; High: URS Altiva, URS Brava and URS 21) were evaluated for the state of expression of descriptors in response to the application of 100 g a.i ha-1 of trinexapac-ethyl when the primary stalk had the first visible node and the second perceptible node. Over two years, the experiments were carried out with different rainfall conditions (2017/2018), in a split-plot design, with three replications. The phenotypic variability in response to product application varied according to cultivar and year. Seven out of 23 descriptorschanged the state of expression in response to trinexapac-ethyl, in greater magnitude for plant length, followed by lemma length and panicle branching position, cycle, floral and glume axis lengths, and density of plants panicle. Trinexapac-ethyl reduced plant length, floral axis and glume, anticipated flowering, increased panicle density and lemma length. Regardless of year, the cultivars with the greatest phenotypic stability to the application of trinexapac-ethyl were Brisasul (96%) and Taura (91%), and the least stable was URS Altiva (83%). The stability of the other cultivars was yeardependent, with the greatest change in phenotypic expression in the year of lower water availability. |

En este trabajo, seis cultivares de avena blanca de diferente clase de estatura (Baja: Brisasul y URS Taura; Media: IPR Artemis; Alta: URS Altiva, URS Brava y URS 21) fueron evaluados en cuanto al estado de expresión de los descriptores en respuesta a la aplicación de 100 g i.a ha-1 de trinexapac-ethyl cuando el tallo primario presentó el primer nudo visible y el segundo perceptible. Los experimentos se llevaron a cabo en dos años con distintas condiciones de lluvia (2017/2018), en diseño de parcela subdividida, con tres repeticiones. La variabilidad fenotípica en respuesta a la aplicación del producto varió según el cultivar y el año. De los 23 descriptores, siete modificaron el estado de expresión en respuesta al trinexapac-ethyl, en mayor magnitud para la longitud de la planta, seguida de la longitud del lema y la posición de las ramas en la panícula, el ciclo, las longitudes del eje floral y de las glumas, y la densidad de la panícula. Trinexapac-ethyl redujo la longitud de la planta, el eje floral y la gluma, anticipó la floración, aumentó la densidad de la panícula y la longitud de la lemma. Independientemente del año, los cultivares con mayor estabilidad fenotípica a la aplicación de Trinexapac-ethyl, fueron Brisasul (96%) y Taura (91%), y el menos estable fue URS Altiva (83%). La estabilidad de los otros cultivares dependía del año, con un mayor cambio en la expresión fenotípica en el año de menor disponibilidad de agua.O trinexapac-ethyl reduz o acamamento em aveia-branca, mas seu uso em campos de produção de semente requer o conhecimento do seu impacto sobre a expressão de descritores, sob pena de comprometer a identificação de cultivares. Neste trabalho, seis cultivares de aveia-branca de distinta classe de estatura (Baixa: Brisasul e URS Taura; Média: IPR Artemis; Alta: URS Altiva, URS Brava e URS 21) foram avaliadas quanto ao estado de expressão de descritores em resposta à aplicação de 100 g i.a ha-1 de trinexapac-ethyl quando o colmo primário apresentava o primeiro nó visível e o segundo nó perceptível. Os experimentos foram conduzidos em dois anos com distinta condição pluviométrica (2017/2018), em delineamento de parcela subdividida, com três repetições. A variabilidade fenotípica em resposta à aplicação do produto variou conforme a cultivar e o ano. De 23 descritores, sete modificaram o estado de expressão em resposta ao trinexapac-ethyl, em maior magnitude para comprimento de planta, seguido do comprimento do lema e posição das ramificações na panícula, ciclo, comprimentos de eixo floral e de gluma, e densidade de panícula. O trinexapac-ethyl reduziu comprimento de planta, eixo floral e gluma, antecipou o florescimento, aumentou densidade de panícula e o comprimento do lema. Independentemente de ano, as cultivares com maior estabilidade fenotípica à aplicação do trinexapac-ethyl, foi Brisasul (96%) e Taura (91%), e a menos estável foi URS Altiva (83%). A estabilidade das demais cultivares foi dependente do ano, com maior alteração de expressão fenotípica no ano de menor disponibilidade hídrica.
