A procedure whereby mature conifer somatic embryos are treated to provide embryos which have improved viability and/or are viable after a period of storage. The procedure involves supporting the embryos out of direct contact with any nutrient containing medium and any liquid(s) on a surface that is substantially porous to water vapour, and then sealing the embryos in a gas environment containing but having spaced from the embryos water and/or a water containing matrix.

Ce procédé consiste notamment à maintenir les embryons hors de tout contact direct avec tout milieu contenant des éléments nutritifs et avec tout liquide, sur une surface sensiblement poreuse à la vapeur d'eau, puis à emprisonner les embryons dans un milieu gazeux contenant de l'eau et/ou une matrice contenant de l'eau, mais à une certaine distance des embryons.
