Abstract: A process for the multiplication of plant varieties which comprises the following operations: grafting of the variety to be reproduced on the tendril of a mother plant at various levels; production of cuttings of said grafted tendril, and rooting of said grafted cuttings of tendril. The process allows in particular the complete "rooting" of the graft (100%), the dematerialization of the product, the intensification of the density of cultivation. It also gives a high speed of multiplication and a prolonged biological and structural preservation. The invention also includes the product obtained through the process.
