chip budding, a popular method for the budding of vines, with a long history. It is known as the yema bud in Europe and California. During the first growing season of the rootstock, a piece is cut from its original wood and a matching chip piece with a bud is cut from a scion cutting. The chip is inserted in the stock with cambium zones matching, then wrapped tightly with budding tape (see illustration). Chip budding, which may take place at any time of year, may also be used for top grafting.
