Importancia del cultivo del grelo

Abstract

[ES] Los grelos son un cultivo perteneciente a la especie Brassica rapa, que se cultivan desde hace siglos en Galicia (noroeste de España). Esta especie hortícola produce tres productos diferentes que ocupan un lugar destacado en la agricultura tradicional gallega: nabos (raíz engrosada) para alimentación del ganado, nabizas (hojas vegetativas) y grelos (tallos florales) para alimentación humana. En España, es el tercer cultivo en importancia por detrás del brécol y la coliflor, producida casi en su totalidad en Galicia con 6.800 ha. En Europa, cultivos similares se encuentran ampliamente distribuidos en Italia y Portugal. Son alimentos ricos en proteínas, vitaminas A, E, C y minerales como hierro, calcio y potasio y compuestos fenólicos con un papel antioxidante. Además, contienen grandes cantidades de un tipo de fitoquímicos denominados glucosinolatos, principales responsables de las cualidades organolépticas, nutritivas y medicinales del cultivo. Ante la importancia del cultivo de esta hortaliza en la comunidad gallega, la Consellería do Medio Rural y los productores de grelos impulsaron una marca de calidad reconocida por la Unión Europea: 'Indicación Xeográfica Protexida Grelos de Galicia' (IXP), lo que augura un futuro prometedor para este cultivo.

[EN] Turnip tops are crops belonging to the species Brassica rapa, which have been cultivated for centuries in Galicia (northwest Spain). This horticultural species produces three different products that occupy a prominent place in Galician traditional agriculture: turnips (thickened root) for animal feeding, turnip greens (vegetative leaves) and turnip tops (floral stems) for human feeding. In Spain it is the third crop in importance behind the broccoli and cauliflower, produced almost entirely in Galicia with 6.800 ha. In Europe, similar crops are widely distributed in Italy and Portugal. They are foods rich in proteins, vitamins A, E, C and minerals like iron, calcium and potassium and phenolic compounds with an antioxidant role. Additionally, they contain large amounts of a type of phytochemical called glucosinolates, responsible for the organoleptic, nutritional and medicinal qualities of the crop. Given the importance of the cultivation of this vegetable in the Galician community, the Consellería do Medio Rural and the producers of turnip top promoted a quality mark recognized by the European Union 'Indicación Xeográfica Protexida Grelos de Galicia' (IXP), which augurs a promising future for this crop.
