The regeneration of Peucedanum palustre (L.) Moench (milk parsley) was established for the first time via somatic embryogenesis from primary root cultures. Callus formation occurred on the root cultures and showed spontaneous embryogenic capability on B5 basal medium supplemented with a low concentration of indoleacetic acid (5.5 × 10−7 M). 2,4-Dichlorophenoxyacetic acid was not needed for the initiation of embryogenesis. The somatic embryos germinated and formed plantlets on hormone-free B5 medium. These plantlets were easily transferable to pots, and are presently passing their second growing season in the greenhouse.
Development of the somatic embryos progressed through the globular, heart-shaped, torpedo-shaped, and cotyledonary stages, typical of zygotic embryos. Synchronization performed by sieving the embryos did not affect the development time. The culture has retained its embryogenic capacity for 25 months.
