A PROCEDURE FOR THE PRODUCTION OF GRAFTED OFFSHOOTS USING GRAFT BASES AND DOWNY OFFSHOOTS THAT COME FROM THE 'IN VITRO' CULTIVATION OF VITIS VINIFERA.

摘要

Starting with a herbaceous cutting which is, or is not, derived from an IN-VITRO culture of a root stock and a herbaceous graft, the process consists in inserting the graft (12'), which comprises a single bud, into the root stock cutting (12), by cutting the lower part 15 of the graft 12' so that it forms two sloping edges 17, 18, by making an incision in the centre of the upper part of the root stock cutting, followed by combining the two parts 12, 12' by fitting them together 20, introducing the base of the abovementioned grafted unit in a development medium 21, moistening the development medium 21 with a nutritive solution, followed by placing this unit into an incubator with a water-saturated atmosphere and at a temperature of above 20 DEG C, while removing the bud 22 borne on the root stock, and raising the plants in the greenhouse or under a protective tunnel until they have reached the desired stage of growth. …IMAGE…
