Resumen
El Cromo (Cr) es el séptimo metal más abundante en la corteza terrestre, varía entre los 100 y los 300 μg/g. Sin embargo, la inadecuada disposición de desechos provenientes de procesos industriales lo han convertido en un importante contaminante ambiental. Los componentes del cromo son perjudiciales para las plantas afectando su crecimiento y desarrollo, por lo que es necesario establecer estrategias para remover el metal de los suelos contaminados y a la vez proteger a las plantas para evitar la disminución de su productividad. En este trabajo, se utilizaron plantas de maíz de dos variedades híbridas, Puma PT3 Poncho y Albatros, para evaluar su tolerancia al Cromo en condiciones de crecimiento in vitro, resultando más tolerante en el follaje la variedad Puma, que aunque redujo su crecimiento en concentraciones de 100 a 1000 μM del metal, continuó con su crecimiento.
