Popis: Calli from cotyledon, hypocotyl and radicle explants of Erysimum scoparium (Brassicaceae) were induced and cultured using a MS medium without growth regulators. Calli obtained from cotyledon or hypocotyl explants showed a higher growth rate while radicle-derived calli exhibited poor growth. Cotyledon-derived calli were compact and green-colored while hypocotyl- and radicle-derived calli were friable and with creamy-green pigmentation. Histological analysis was carried out during culture and the development of abundant vascular elements and meristematic nodules were found. Subculture on a growth regulator-free medium during 10 months did not ecrease callus growth.
