Organogenesis from Callus Culture of Hordeum vulgare.

Rapidly proliferating callus cultures from the apical meristem of Hordeum vulgare L., cultivars "Himalaya" and "Mari", were established on a defined medium supplemented with auxin and cytokinin. A frequency of organ differentiation of ca. 85% was obtained by transfer to the same medium but without any growth regulators. All regenerated plants had the diploid chromosome number of 14 (2n).
