Use of abscisic acid in somatic embryogenesis of pine trees

摘要

One aspect of the invention provides methods for producing cotyledonary pine embryos. The methods of the invention comprise the steps of: (a) culturing pre-cotyledonary pine somatic embryos in a development medium comprising abscisic acid and an adsorbent composition; and (b) culturing the pre-cotyledonary pine somatic embryos treated in accordance with step (a) in a development medium that does not include abscisic acid to yield cotyledonary pine somatic embryos.
