Resumo: Zinc (Zn) and iron (Fe) are the most deficient nutrients in the world population. Agronomic biofortification of Zn aims to increase concentration of the micronutrient in edible parts of staple crops without negatively affecting yield. However, the increase in grain Zn accumulation may affect grain Fe accumulation and bioavailability. In order to study these micronutrients in wheat grains, the objective of this study was to evaluate the concentrations of Zn and Fe in grains of wheat cultivars and to verify the effect of foliar Zn spraying to improve grain nutritional quality without negatively affecting yield. The field experiment was carried out in a randomized block design with four replicates, in a split-plot scheme, with plots being composed of five wheat cultivars widely cultivated in Southern Brazil (ORS 1403, ORS Vintecinco, BRS Gralha Azul, BRS Sabiá e TBIO Sintonia) and subplots composed of four Zn doses (0, 250, 500 e 1000 g ha-1) applied via foliar spraying at the maturation phenological stage. Grain yield varied between cultivars from 1328 to 4333 kg ha-1, but there was no significant effect of leaf Zn spraying. There was genotypic variation as to ability of the wheat cultivars to accumulate Zn in grains. The cultivars had different responses in grain Zn accumulation due to the foliar Zn spraying. There was an inverse relationship between Zn and Fe accumulation in the grains in four wheat cultivars.

La biofortificación agronómica de Zn tiene como objetivo aumentar la concentración del micronutriente en los granos sin afectar negativamente la productividad. Sin embargo, el aumento de la acumulación de Zn en los granos puede afectar la acumulación y la biodisponibilidad de Fe. Para estudiar estos micronutrientes en granos de trigo, el objetivo de este estudio fue evaluar los contenidos de Zn y Fe en granos de los cultivares de trigo y verificar el efecto de la pulverización foliar de Zn para mejorar la calidad nutricional de los granos sin afectar negativamente la productividad. El experimento de campo se llevó a cabo en un diseño de bloques al azar con cuatro repeticiones, en un esquema de parcelas subdivididas, siendo las parcelas compuestas por cinco cultivares de trigo ampliamente cultivados en la región sur de Brasil (ORS 1403, ORS Vintecinco, BRS Gralha Azul, BRS Sabiá y TBIO Sintonia ) y las subparcelas compuestas por cuatro dosis de Zn (0, 250, 500 y 1000 g ha-1) aplicadas vía foliar en la etapa fenológica de la maduración del grano. La productividad de los granos varió entre los cultivares, presentando valores entre 1328 y 4333 kg ha-1, pero no hubo un efecto significativo de la pulverización foliar de Zn. Hubo variación genotípica en cuanto a la capacidad del trigo para acumular Zn en los granos. Los cultivares tuvieron diferentes respuestas con respecto a la capacidad de acumular Zn en los granos en función de la pulverización foliar de este micronutriente. Se verificó una relación inversa entre la acumulación de Zn y Fe en los granos de los cultivares de trigo.O zinco (Zn) e o ferro (Fe) são os micronutrientes mais deficientes na população mundial. A biofortificação agronômica de Zn visa aumentar a concentração do micronutriente nos grãos sem negativamente afetar a produtividade. Entretanto, o aumento do acúmulo de Zn nos grãos pode afetar o acúmulo e a biodisponibilidade de Fe. Visando estudar esses micronutrientes em grãos de trigo, a presente pesquisa teve como objetivo investigar os teores de Zn e Fe em grãos de cultivares de trigo e verificar o efeito da pulverização foliar de Zn para melhorar a qualidade nutricional dos grãos sem afetar negativamente a produtividade. O experimento de campo foi conduzido em DBC com quatro repetições, em esquema de parcelas subdivididas, sendo as parcelas compostas por cinco cultivares de trigo amplamente cultivadas na região Sul do Brasil (ORS 1403, ORS Vintecinco, BRS Gralha Azul, BRS Sabiá e TBIO Sintonia) e as subparcelas compostas por quatro doses de Zn (0, 250, 500 e 1000 g ha-1) aplicadas via foliar no estádio fenológico de maturação de grãos. A produtividade de grãos variou entre as cultivares, apresentando valores entre 1328 a 4333 kg ha-1, mas não houve efeito significativo da pulverização foliar de Zn. Houve variação genotípica quanto à capacidade do trigo em acumular Zn nos grãos. As cultivares tiveram diferentes respostas quanto à capacidade de acumular Zn nos grãos em função da pulverização foliar desse micronutriente.
