We developed a new technology to induce embryoids by a moderate high t
emperature treatment from multiple shoots of Panax ginseng (Araliaceae
). The number of formed embryoids was 10 times higher than that of unt
reated tissue. Normal plantlets were regenerated from the embryoids by
transplanting them on a hormone-free medium. They contained ginsenosi
des Rb1, Rg1 and the other saponins as well as those of natural ginsen
g.
