| Abstract: | A protocol was developed for regeneration of pepper (Capsicum annuum var. Ace) through somatic embryogenesis in liquid media. For embryogenic callus formation, mature zygotic embryo explants were used on basal Murashige and Skoog medium with 9.05  M 2,4-dichlorophenoxyacetic acid and 3% sucrose. Embryogenic callus was transferred to liquid basal Murashige and Skoog medium with 4.52 M 2,4-dichlorophenoxyacetic acid and 3% sucrose in order to increase the mass of the embryogenic culture. After pretreatment with potassium citrate, cells were placed into embryo initiation medium with 6 g l-1l-proline and a decreased (10 mM) ammonium concentration. Embryos were matured in 1.89 M abscisic acid containing half-strength Murashige and Skoog medium and converted into plants bothin vivo andin vitro at up to a 97% efficiency. |
