Abstract
The present invention relates to an improved method for generating somatic embryos from mature plant tissue. The treatment methods of the present invention use a combination of disinfestation procedures and plant growth regulator compositions which induce unequal cell division. After forming and maturing the somatic embryos on suitable growth media, the mature somatic embryos are desiccated and cold stratified resulting in an dramatic increase in the percentage of somatic embryos which may be converted into plants.
