Euphorbia pulcherrima Willd. is one of the most popular ornamental houseplants. A protocol was developed for multiplication of E. pulcherrima through somatic embryogenesis from nodal explants. The induction of somatic embryogenesis in red pigmented callus was achieved on MS supplemented with 2ip (9.8 ?M) and NAA (2.69 ?M). Reduced level of NAA (0.54 ?M) in the same medium caused maturation of somatic embryoids. The embryoids germinated successfully, turned into plantlets and were established in field with a high survival rate.
