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.
Claims2
Cotyledonary tissues of asexual embryos produced by the following steps:
- (A) proliferation of immature zygotic cacao embryos in a basal medium in the presence of a growth enhancer whereby asexual embryos are initiated upon said zygotic embryos;
- and
- (B) growing said asexual embryos in vitro in a basal medium;
- (C) harvesting the cotyledonary tissue of said asexual embryos.
An asexual embryo capable of forming cotyledonous tissue produced by the following steps:
- (A) proliferation of immature zygotic cacao embryos in a basal medium in the presence of a growth enhancer whereby asexual embryos are initiated upon said zygotic embryos;
- and
- (B) growing said asexual embryos in vitro in a basal medium.
