Copper toxicity effect on the germination process and growth parameters of Armagnac hybrid of corn. On Cu-treated samples, germination was slowed and the mass & length of coleoptiles and roots reduced significantly. Copper toxicity has effected also enzymatic activities of ''Armagnac'', Cu in the seed induced abiotic stress, which resulted in the formation of reactive oxygen species (ROS) and oxidative stress, each of which had a distinct influence on the interactions.
