Embryo Culture - In embryo culture, young embryos are removed from developing seeds and placed on a suitable nutrient medium to obtain seedlings. The cultured embryos generally do not complete development, but germinate prematurely. Some times, embroys from mature seeds may also be used for embryo culture, e.g., in Iris orchids, etc.

So far, it has not been possible to culture embroys, before a certain stage of development, for example, before the globular stage in the case of barley. But in case of some species, e.g., Brassica, very young embryos of few cells have been successfully cultured. Young embryos need to be isolated with their suspensors intact as it provides gibberellins to the developing embryo.
