Somatic embryogenesis and plant regeneration from in-vitro-grown leaf explants of rose Academic Article uri icon


  • Somatic embryogenesis was initiated from in vitro-grown leaf explants of rose using an induction period of 4 weeks on MS basal medium supplemented with auxin followed by several subcultures on MS basal medium with cytokinin. `4th of July' showed the highest regeneration frequency (24.4%) on 5.3 m NAA followed by culture on medium containing 18.2 m zeatin. `Tournament of Roses' produced somatic embryos when cultured for 4 weeks on medium containing dicamba, 2.3 m followed by three subcultures on medium containing 18.2 m zeatin. Embryogenic callus matured on MS media containing 0.5 m NAA, 6.8 m zeatin, and 2.9 m GA3. Long-term cultures were established for both cultivars. Somatic embryos germinated on MS medium containing IBA and BA. Silver nitrate (58.8 m) enhanced shoot formation and germination of somatic embryos. Plants derived from somatic embryos were acclimatized and successfully established in the greenhouse.
