An Article on Replacing and Renewing Spurs and Arms on the Grapevine
These are commonly referred to as the primary , secondary, and tertiary buds , respectively. At bud burst, the primary bud is typically the only bud that begins to grow. These secondary and tertiary buds generally have little to no fruit in comparison to the primary bud. Suckers and Watersprouts. Latent buds embedded in older trunk and cordon wood may also produce shoots. Suckers are shoots that grow from the crown area of the trunk.
Watersprout is sometimes used to refer to a shoot arising from the upper regions of the trunk or from cordons Winkler et al. Buds growing from older wood are not newly initiated buds, but rather they developed on green shoots as axillary buds that never grew out. These latent buds can remain dormant indefinitely until an extreme event such as injury to the vine or very severe pruning stimulates renewed development and shoot growth Winkler et al.
Suckers often arise from latent buds at underground node positions on the trunk. In routine vine management, suckers are removed early in the season before axillary buds can mature in basal bracts of the sucker shoots. Similarly, above-ground suckers are typically stripped off the trunk manually so a pruning stub does not remain to harbor additional latent buds that could produce more suckers in the following year.
Latent buds come into use when trunk, cordon, or spur renewal is necessary. Dormant secondary and tertiary buds exist in the stubs that remain after canes or spurs have been removed by pruning. The shoot enters a transitional phase, starting around veraison , when it begins to mature or ripen. As periderm develops, it changes from yellow to brown, and becomes a dry, hard, smooth layer of bark.
During shoot maturation, the cell walls of ray tissues thicken and there is an accumulation of starch storage carbohydrates in all living cells of the wood and bark Mullins et al. Once the leaves fall from the vine at the beginning of the dormant season, the mature shoot is considered a cane.
The cane is the principal structure of concern in the dormant season, when pruning is employed to manage vine size and shape, and to control the quantity of potential crop in the coming season. Because a cane is simply a mature shoot, the same terms are used to describe its parts. Pruning severity is often described in terms of the number of buds retained per vine or bud count.
This refers to the dormant buds, which in a single bud contains three growing points as described above. It should be noted that the most basal buds on a cane are generally not fruitful and do not grow out, so they are not included in bud counts.http://technologybullets.com/wp-content/2019-07-14/wypa-empleo-limpieza.php

These are often referred to as non-count buds during the pruning process. Canes can be pruned to varying lengths, and when they consist of only one to four buds, they are referred to as spurs, or often, fruiting spurs. Grapevine spurs should not be confused with true spurs produced by apple, cherry, and other fruit trees, which are the natural fruit-bearing structures of these trees.
On grapevines, spurs are created by short-pruning of canes. Training systems that use cane-pruning also use spurs for the purpose of growing shoots to be trained for fruiting canes in the following season. These spurs are known as renewal spurs, indicating their role in replacing the arms. Mullins, M. Bouquet, and L. Biology of the Grapevine. Cambridge University Press. Pratt, C.
