For example, grape rootstocks descended from North American grapes allow European grapes to be grown in areas infested with Phylloxera, a soil-dwelling insect that attacks and kills European grapes when grown on their own roots. Two of the most common grafting techniques are "whip and tongue", carried out in spring as the sap rises, and ...
The Chip Bud Method is performed shortly after the grape vine is planted, giving the rootstock enough time to become active but the bud of the grape vine is still inactive. It is performed by cutting two small slopes in both sides of the rootstock and cutting a small scion into a small bud and placing the scion bud into the cuts made on the ...
AxR1 is a grape rootstock once widely used in California viticulture.Its name is an abbreviation for "Aramon Rupestris Ganzin No. 1", which in turn is based on its parentage: a cross (made by a French grape hybridizer named Ganzin) between Aramon, a Vitis vinifera cultivar, and Rupestris, an American grape species, Vitis rupestris—also used on its own as rootstock, "Rupestris St. George" or ...
Others, opposed to the idea, argued that American rootstocks would imbue the French grapes with an undesirable taste; they instead preferred to inject the soil with expensive pesticides.

Such clones have arisen through mutation of a regular ("non-musqué") clone of the variety, and such mutations have been recorded for several different grape varieties. [ 1 ] The most well-known musqué grape is Gewürztraminer , which is a musqué mutation of a red-skinned Traminer , which is also known as Savagnin rose in France. [ 2 ]
