Abstract

Explants from three different parts (cotyledon, hypocotyl or root) of one week-old seedlings of Eleutherococcus senticosus were cultured on Murashige and Skoog (MS) medium with 1.0 mg l-1 2,4-D. Somatic embryos were formed directly from the surfaces of explants. The frequency of direct somatic embryo formation was the highest in the hypocotyl segments (75%) as compared to cotyledon (56%) or root segments (12%). When hypocotyl explants from 3 different stages of seedlings (zero, one or three week-old) were cultured on MS medium with 1.0 mg l-1 2,4-D, the frequency of somatic embryo formation rapidly declined as the zygotic embryos germinated. However most somatic embryos (93%) from explants of zygotic embryos developed as fused state (multiple embryo), whereas somatic embryos (over 89%) from more developed seedlings developed into single state (single embryo). Single embryos germinated and regenerated into plantlets with both shoots and roots, while multiple embryos only regenerated into only multiple shoots. Plantlets that regenerated from single embryos of E. senticosus were acclimatized in a greenhouse.
