RootstockPlant root system Grafting, 1870, by Winslow Homer—an example of grafting A rootstock is part of a plant, often an underground part, from which new above-ground growth can be produced. It could also be described as a stem with a well developed root system, to which a bud from another plant is grafted. It can refer to a rhizome or underground stem.
Vitis viniferaVitis vinifera, the common grape vine, is a species of flowering plant, native to the , Central Europe, and southwestern Asia, from Morocco and Portugal north to southern Germany and east to northern Iran. As of 2012, there were between 5,000 and 10,000 varieties of Vitis vinifera grapes though only a few are of commercial significance for wine and table grape production. The wild grape is sometimes classified as Vitis vinifera var.
GraftingGrafting or graftage is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion () while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together. The natural equivalent of this process is inosculation.
ViticultureViticulture (Latin: vitis cultura, 'vine-growing'), viniculture (vinis cultura, 'wine-growing'), or winegrowing is the cultivation and harvesting of grapes. It is a branch of the science of horticulture.WinemakingWinemaking, wine-making, or vinification is the production of wine, starting with the selection of the fruit, its fermentation into alcohol, and the bottling of the finished liquid. The history of wine-making stretches over millennia. There is evidence that suggests that the earliest wine production took place in Georgia and Iran around 6000 to 5000 B.C. The science of wine and winemaking is known as oenology. A winemaker may also be called a vintner.
Cutting (plant)A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems.Layering (horticulture)Plant propagation technique Layering Layering is a vegetative propagation technique where the stem or branch of a plant is manipulated to promote root development while still attached to the parent plant. Once roots are established, the new plant can be detached from the parent and planted. Layering is utilized by horticulturists to propagate desirable plants. Natural layering typically occurs when a branch touches the ground, whereupon it produces adventitious roots.
Annual growth cycle of grapevinesThe annual growth cycle of grapevines is the process that takes place in the vineyard each year, beginning with bud break in the spring and culminating in leaf fall in autumn followed by winter dormancy. From a winemaking perspective, each step in the process plays a vital role in the development of grapes with ideal characteristics for making wine.
Old vineOld vine (French: vieilles vignes, German: alte Reben), a common description on wine labels, indicates that a wine is the product of grape vines that are notably old. There is a general belief that older vines, when properly handled, will give a better wine. There is no legal or generally agreed definition for old. UsageGrape vines can grow for over 120 years.
Canopy (grape)In viticulture, the canopy of a grapevine includes the parts of the vine visible aboveground - the trunk, cordon, stems, leaves, flowers, and fruit. The canopy plays a key role in light energy capture via photosynthesis, water use as regulated by transpiration, and microclimate of ripening grapes. Canopy management is an important aspect of viticulture due to its effect on grape yields, quality, vigor, and the prevention of grape diseases.
CloningCloning is the process of producing individual organisms with identical genomes, by either natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without a mate is known as parthenogenesis. In the field of biotechnology, cloning is the process of creating cloned organisms of cells and of DNA fragments.
SeedlingA seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves).*As an Amazon Associate I earn from qualifying purchases.
