Somatic Embryogenesis ofRosa HybridaL. [PDF]

Biotechnology & Biotechnological Equipment, 2000
ABSTRACTWe present two regeneration protocols via somatic embryogenesis in three cut roses—Rosa hybrida cvs. “Anny”, “Trimontsium” and “Saltze Gold”. The first regeneration protocols are based on regeneration via somatic embryogenesis in callus from leaf and petiole segments of Rosa hybrida cvs. “Trimontsium” and “Saltze Gold”.
