Term for the transfer of pollen grains from one flower to the stigma of a second flower on another plant (cross-pollination), which triggers cross-fertilization (xenogamy). In the case of the grapevine, this can be a neighboring vine of the same or a vine of any other grape variety from a neighboring vineyard (see below blossom ). In contrast, self-fertilization is within one hermaphrodite flower (Autogamy) or between two different flowers of the same plant (neighboring fertilization = geitonogamy). For the most part, one takes place in cultivated vines selfing (Self-fertilization) within the hermaphrodite flower. At purely female grape varieties must be cross-fertilized by nearby or in mixed sentence planted hermaphrodite varieties are forced. at new varieties a targeted or desired cross-fertilization takes place with the desired partner.
