  • Plant tissue produced by non-agricultural proliferation of cacao embryos
    Patent number: 4301619
    Abstract: This invention is a non-agricultural method for producing cotyledons of those plant species whose cotyledons have commercial value for the manufacture of useful products or for direct use as foodstuffs such as Theobroma cacao L. (cacao). The method involves three (3) distinct steps, namely, (1) proliferation of embryos by asexual embryogenesis through in vitro culture using a defined media; (2) the growth of the embryos in vitro in a media that will prevent premature germination, and (3) harvest of the in vitro-grown cotyledonary tissue.
    Type: Grant
