Grapevine Planting Stock
Types of Grapevine Planting Stock
Traditionally, vineyards have been planted with dormant benchgrafts, but growers have several other options including rooted cuttings, dormant potted vines, and green benchgrafts.
Rooted cuttings are dormant, bare-rooted vines produced by rooting a cutting (a cane section about 12 to 16 in, 30 to 41 cm) and growing it in the field for one season. Although rooted cuttings are less than half the cost of any grafted vines, the additional costs of field budding combined with the greater management requirements and risk, make this approach less desirable today.
The majority of commercially produced vines are propagated by dormant bench grafting. These vines are grafted in the winter, callused (the union of scion/rootstock) in the spring, and planted in the nursery. After one growing season in the nursery the plants are harvested after they become dormant.
Dormant Potted Vines
Dormant potted vines are usually benchgrafted using dormant rootstock and scion cuttings, and grown in containers (plastic pots or paper sleeves) for a season rather than in the field.
Green benchgrafts are similar to dormant potted vines except that they are shipped out in the same year that they are grafted, and they are actively growing. The larger the sleeve or tube that the green-growing vines, are grown in, the greater the root mass that can be obtained prior to planting in a vineyard, and the more quickly the vines will begin shoot growth.
