Propagation of plants in asexual way, that is without seeds. Different parts of a plant (shoots, root parts or, as with many flowers, onions) are planted in the soil, from which roots and shoots can develop. In nature, there is usually a sexual or generative propagation instead, that is, the product is genetically distinct from the parent, which usually produces surviving progeny. But there are also some plants with natural vegetative propagation (eg different species of moss). The vegetative propagation is used in plant breeding for the production of plants in large quantities. In viticulture one understands under it the multiplication by mostly planting of blind vines one Mutterrebe, Since the Rebstock extreme heterozygous (splitterbig) is an increase, that is the production of vines in nurseries, principally on a vegetative path.
at varieties if possible, identical offspring with the same characteristics as the mother's vine are desired. All of our cultivated grape varieties have therefore been propagated vegetatively for hundreds of years, essentially preserving their genetic characteristics. For in contrast to sexual reproduction (generative), the vegetative progeny is almost identical to the mother vine and thus a so-called clone, Another form is the multiplication by means of Absenker, Also the finishing is in principle a vegetative propagation. For some time there has also been micropropagation, in which tiny parts (tissue culture) of a mother vine are used for the relatively rapid breeding of seedlings. The so-called stock division (Distribution of rhizomes) is for the multiplication of vines not suitable. See also below breeding,
