Method for the production of young plants and/or micro-parent stock of 5herbaceous ornamentals. Method for the production of young plants and/or ofmicro-parent stock of herbaceous ornamentals, which comprises an in vitroculture phase during which explants obtained from parent stock of species tobe propagated, or derivatives of these explants, are subjected tomicropropagation which is carried out under suitable conditions and onsuitable culture media, in order to produce micro~plantlets which, whensubjected to an in vivo culture phase, are intended to develop into plants orinto micro-parent stock, characterized in that, to carry out saidmicropropagation: the explants are, under axenic conditions, in the dark andfor a suitable period of time, placed on a proliferation medium which iscomposed to suit each plant species to be propagated, so as to induce theformation of white filaments which comprise axillary buds, each of the whitefilaments is divided into a plurality of pieces, each of 20 which comprises anaxillary bud, and said pieces are, in the light, under axenic conditions andfor a suitable period of time, placed into a rooting medium, which allows eachaxillary bud to produce a micro-plantlet which has roots.
