Plant propagation.

摘要

Plants are micropropagated by a process which comprises forming an aqueous suspension of comminuted plant material, separating from the suspension particles capable of regeneration into plants (propagules), directing the propagules to a plurality of discrete growing sites on a supporting medium supplied with plant growth nutrients, growing the propagules and separating the growing sites and the plantlets or plants grown thereon. The propagules are separated from the suspension by detection of their particle size or morphology e.g. by means of a fluidic switch. The support material is preferably cellulosic e.g. paper pulp or other cellulosic fibrous material.
