This invention provides a seed-germination medium comprising an upper layer (4) formed from a tissue paper having a weight of approximately 10-30 g/m2, the tissue paper being coated or impregnated with a waterproofing agent such that the tissue paper is permeable to gases but substantially impermeable to water in liquid form; a lower layer (6) formed from a water-absorbent biodegradable material; seeds (8) being disposed beneath the upper layer; and the upper layer optionally having a plurality of perforations therein to assist disruption of the upper layer to enable seedlings germinating from the seeds to grow therethrough.
La présente invention concerne un milieu de germination de semences comprenant une couche supérieure (4) formée de papier d'un grammage approximativement de 10-30 g/m<2>, ce papier étant couché ou imprégné au moyen d'un agent imperméabilisant de telle manière que le papier soit perméable aux gaz mais pratiquement imperméable à l'eau sous forme liquide. Ce milieu comprend aussi une couche inférieure (6) formée d'un matériau biodégradable absorbeur d'eau. Des semences (8) sont disposées sous la couche supérieure. La couche supérieure présente éventuellement plusieurs perforations afin de faciliter sa rupture et permettre aux semis en germination de poursuivre leur croissance au travers.
