Hermaphroditic flower

The cultivated grapevine is 99% monoecious (monoecious) with hermaphrodite, i.e. bisexual, flowers. It is 98% self-fertilising, but can also be cross-fertilised. Wild vines are mostly dioecious (dioecious), i.e. there are plants with exclusively male or exclusively female flowers, so that a so-called self-pollination (self-fertilisation) is excluded. In monoecious plants, both sexes occur on one plant.

The flowers can be separate-sexed, so that male and female flowers occur on the same plant but in separate inflorescences, or they are hermaphroditic h ermaphrodite flowers, in which male and female sexual organs are united in one flower. The vine is an angiospermous plant. This means that the flower bud is covered with the perianth, which is opened or shed during flowering to enable pollination (and subsequent fertilisation). As a rule, the cultivated grape varieties are bisexual. However, there are also unisexual (female) varieties with exclusively female flower organs.
