Abstract
Protolasts of Bupleurum scorzonerifolium were prepared from stem node-derived embryogenic calli with an enzyeme mixture, in which snailase was a necessary component. Follolwing cell wall regeneration protoplasts divided and directly formed somatic embryos which developed into plantlets. The conditions favorable to direct embryo formation were investigated, and the nature of the callus used for protoplast preparation was found to be a critical factor. The osmotic concentration and the composition of the culture medium including the phytohormone combinations were also important.
