Method of production of vine saplings has bone grafts - sodas high and plants thus obtained

摘要

The method involves cutting, from graft stock cuttings, a length of between 50 and 90 cm. Prior to planting, operations of disbudding, cutting, grafting and paraffining operations are carried out. Each paraffined graft cutting is then placed in a protective container constituted by a sheath (2) of length equal to that of the stock (1a). The sheath lower part (2a) is shaped to receive and contain the root system and its accompanying substratum (5). The remaining part of the sheath is filled up to the grafting point (1c) with a sterile medium (7). The plants are forced in a local temperature maintained at about 30 deg. under hygrometric saturation for 2 to 3 weeks. Afterwards they are matured in a cold greenhouse for several weeks. At the end of this time the plants are ready to be planted directly in their packaging with the lower part of the sheath buried.
