Abstract
Callus was initiated from immature leaf and stem segments of rose (Rosa hybrida cv. Landora) and subcultured every four weeks on a basal medium of half-strength Murashige & Skoog (1962) salts plus 30 g l-1 sucrose (1/2 MS) and supplemented with 2.2 μM BA, 5.4 μM NAA and 2.2–9.0 μM 2,4-D. Embryogenic callus and subsequently somatic embryos were obtained from 8-week-old callus culture on 1/2 MS+2.2 μM BA+0.05 μM NAA+0.3 μM GA3+200−800 mg l-1 L-proline. Long-term cultures were established and maintained for up to 16 months by repeated subculture of embryogenic callus on L-proline deficient medium. About 12% of cotyledonary stage embryos taken from cultures cold-stored at 8±1°C for 4 days germinated on 1/2 MS+2.2 μM BA+0.3 μM GA3+24.7 μM adenine sulphate.
