Abstract

L'invention concerne un dispositif de greffage susceptible d'améliorer la productivité tout en limitant des variations dans la qualité de plantules greffées. La présente invention concerne un dispositif de greffage servant à effectuer un greffage à l'aide d'un élément de greffage comprenant: un élément de soutien présentant une partie en appui avec laquelle la tige d'une plante de greffage prend appui; et un élément fixe présentant une partie de pression servant à plaquer la tige contre la partie en appui. Le dispositif de greffage comporte: une partie de préhension qui saisit la plante de greffage et dispose la plante de greffage sur l'élément de soutien; une partie de fixation qui fixe l'élément fixe à l'élément de soutien de telle sorte que la tige de la plante de greffage soit plaquée contre la partie en appui; une partie de découpe qui obtient un greffon et un porte-greffe en coupant la plante de greffage et divise l'élément de soutien en une unité de greffon qui contient le greffon et une unité de porte-greffe qui contient un porte-greffe; et une partie de jonction qui joint le greffon et le porte-greffe en fixant l'unité de porte-greffe à l'unité de greffon.
