Förfaranden för framställning av hjärtbladsförsedda tallembryon under utnyttjande av en gibberelin

摘要

The present invention provides methods for producing cotyledonary pine embryos. The methods of the invention each include the step of culturing embryogenic pine tissue in, or on, a medium including at least one gibberellin to yield cotyledonary pine embryos. In some embodiments, an absorbent composition, such as activated charcoal, is included in the medium to further promote production of cotyledonary pine embryos.
