DEFINITION

  • There exists no clear definition for what are called facultative or alternative wheats. According to Stelmakh (1998), they are usually characterized by strong photosensitivity and partial sensitivity to vernalization.Facultative wheats have, compared to true winter wheats, in general less cold tolerance, a shorter but distinct period required for vernalization, start growth in spring earlier and flower earlier. They are mainly grown in areas with milder winters, areas with late fall rains or when late sowing is required due to tight crop rotations. (en)
