  • Description: Biofortification of food crops is implemented through the application of mineral fertilizers, to improve the levels of essential mineral elements for human nutrition. Magnesium is a key macronutrient in crop production and quality; however, worldwide, it is the most limiting macronutrient in agriculture. Magnesium plays an important role in manipulating physiological and biochemical processes in plants. Therefore, the objective of this study was to evaluate the efficacy of biofortification with magnesium chloride and sulfate on the accumulation of bioactive compounds and antioxidant capacity in snap bean cv Strike. Two sources of Magnesium were applied via edaphic route: Magnesium chloride and magnesium sulfate at doses of 0, 50, 100 and 200 ppm during 2018 in Mexico. Accumulation of bioactive compounds (total phenols, total flavonoids and total anthocyanins) and antioxidant capacity in snap bean fruits were evaluated. Results obtained indicate that the concentration of total flavonoids, total anthocyanins and antioxidant capacity in the edible parts of snap beans were higher in the [MgSO.sub.4] treatment than in the [MgCl.sub.2] treatments, exceeding 30, 59 and 6% respectively. This is one of the first studies on the edaphic agronomic biofortification of [Mg.sup.+] and its effect on nutraceutical quality in snap bean. An interesting result is that [MgSO.sub.4] produced high concentrations of anthocyanins in edible snap beans. These results can be applied as a new strategy to reduce malnutrition and improve the health of the population in poor urban and rural communities in developing countries. Key words: anthocyanins, antioxidant capacity, edaphic biofortification, flavonoids. A biofortificaqao de culturas alimentares e implementada atraves da aplicaqao de fertilizantes minerais, para melhorar os niveis de elementos minerais essenciais para a nutriqao humana. O magnesio e um macronutriente essencial na produqao e qualidade das culturas, no entanto, em todo o mundo, e o macronutriente mais limitante da agricultura. O magnesio desempenha um papel importante na manipulaqao de processos fisiologicos e bioquimicos nas plantas. Portanto, o objetivo deste estudo foi avaliar a eficdcia da biofortificaqao com cloreto e sulfato de magnesio no acumulo de compostos bioativos e capacidade antioxidante em feijoes verdes cv. Strike. Duasfontes de magnesio foram aplicadas por via edafica: cloreto de magnesio e sulfato de magnesio nas doses de 0, 50, 100 e 200 ppm durante o ano de 2018 no Mexico. Foram avaliados o acumulo de compostos bioativos (fenois totais, flavonoides totais e antocianinas totais) e a capacidade antioxidante em frutos de feijao-vagem. Os resultados obtidos indicam que a concentraqao de flavonoides totais, antocianinas totais e capacidade antioxidante nas partes comestiveis do feijao-vagem foram maiores no tratamento com [MgSO.sub.4] do que nos tratamentos com [MgCl.sub.2], ultrapassando 30, 59 e 6% respectivamente. Este e um dos primeiros estudos sobre a biofortificaqao agronomica eddfica do [Mg.sup.+] e seu efeito na qualidade nutraceutica do feijao-vagem. Um resultado interessante e que o [MgSO.sub.4] produziu altas concentraqoes de antocianinas no feijao-vagem comestivel. Esses resultados podem ser aplicados como uma nova estrategia para reduzir a desnutriqao e melhorar a saude da populaqao em comunidades urbanas e rurais pobres em paises em desenvolvimento. Palavras-chave: antocianinas, capacidade antioxidante, biofortificaqao eddfica, flavonoides.
