Description & Remarks

This plant have been domesticated in our area. The spontaneous species related to it is Hordeum_spontaneum. The spike axis is not brittle in H. distichum, enabling the grower to collect-harvest all the crop. The spontaneous plant has to protect its seeds from the external hazards of variable climate, granivorous animals, and wild fires. There is no way H. distichum can survive out of fields unless the seeds arrive to a habitat where natural vegetation have been destructed. Such a habitat is the sides of roads, sprayed with herbicides. It is accompanied there by Hordeum_vulgare, Triticum_aestivum, Secale_cereale, and other cultivars.
