The latter method requires more labor-intensive trellising and training for Vitis vinifera vines which are naturally more inclined to grow upwards rather than down. In systems such as the Scott Henry, this downward growth is achieved by the use of movable wires that first allow the canes to grow upwards until about 2 to 3 weeks before harvest ...
In biology, the BBCH-scale for grapes describes the phenological development of grapes using the BBCH-scale. The phenological growth stages and BBCH-identification keys of grapes are: Growth stage
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 ...
In viticulture, the grape cluster (also bunch of grapes) is a fertilized inflorescence of the grapevine, the only part of this plant used for food. [1] The size of the grape bunch greatly varies, from few grams to kilograms, depending on the grape variety and conditions during the fruit set .

Following fruit set, the grape berries are green and hard to the touch. They have very little sugar and are high in organic acids. They begin to grow to about half their final size when they enter the stage of veraison. This stage signals the beginning of the ripening process and normally takes place around 40–50 days after fruit set.
A plant on which grapes grow. Vine density The number of vines per a define area of land (acres, hectare, etc). This can be influenced by many factors including appellation law, the availability of water and soil fertility and the need for mechanization in the vineyard. In many wine regions vine density will vary from 3000 to 10000 vines per ...
Various viticulture problems, such as uneven grape ripening, sunburn, and frost damage, can be addressed by skillful canopy management. [2] [3] In addition to pruning and leaf trim, the canopy is often trained on trellis systems to guide its growth and assist in access for ongoing management and harvest. [4]
