hermaphrodite flower

The cultivated grapevine is mostly monoecious (monoecious) with hermaphrodite, that is, two-sexed flowers. It is self-pollinated, but can also be cross-pollinated Wild vines are mostly dioecious, that is, there are plants with exclusively male or exclusively female blossoms, so that thereby a so-called selfing (Self-fertilization) is excluded. In monoecious plants, both sexes occur on a plant. The flowers may be of different sexes, so that male and female flowers are, or are, on the same plant, but in separate inflorescences hermaphroditic Hermaphrodite flowers in which male and female sexual organs are united in one flower. The vine is a bedecktsamige plant. That is, the flower bud is covered with perianth (perianthum), which in the period of blossom is opened or dropped, thereby enabling a pollination (and immediately following fertilization). As a rule, the cultivated grape varieties are two-sexed. But there are also unisexual (female) varieties exclusively female Floral organs.
