摘要
The invention provides a nutrient medium useful for sowing a somatic plant embryo or germinant of conifer species, which comprises particles of a solid component present within a flowable or semi-solid component containing water and a carbohydrate nutrient for the embryos or germinants. The nutrient medium has a fluidity such that at least some of the flowable or semi-solid component containing the carbohydrate nutrient remains in contact with the embryos or germinant at least until the embryo or germinant establishes vigorous growth under environmental conditions effective for such growth. The particles of the solid component are adapted to remain in contact with the embryo or germinant after of the flowable or semi-solid material dissipates, thereby providing continuing physical support for the embryo or germinant after the dissipation.
