Male flowers appear in open clusters while females flowers, distinguished by a swollen base, usually appear individually. The plant is self-fertile, i.e. pollen from the male flowers can fertilise the female flowers on the same plant; pollination is by insects. Fruit Marah macrocarpa fruit
The flower can vary in color from yellowish green to cream to white. Flowers appear soon after the vine emerges. The flowers are monoecious, that is, individual flowers are either male or female, but both sexes can be found on the same plant. Male flowers appear in open spikes while females flowers, distinguished by a swollen base, usually ...
Cucumbers may also be pollinated via bumblebees and several other bee species. Most cucumbers that require pollination are self-incompatible, thus requiring the pollen of another plant in order to form seeds and fruit. [10] Some self-compatible cultivars exist that are related to the 'Lemon cucumber' cultivar. [10]
Androdioecious: having male flowers on some plants, bisexual ones on others. [6] Androecious: having only male flowers (the male of a dioecious population); producing pollen but no seed. [16] Androgynous: see bisexual. [6] Androgynomonoecious: having male, female, and bisexual flowers on the same plant, also called trimonoecious. [16]
Monoecy often co-occurs with anemophily, [2] because it prevents self-pollination of individual flowers and reduces the probability of self-pollination between male and female flowers on the same plant. [4]: 32 Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. [5]
The sole species is E. lobata, commonly called wild cucumber and prickly cucumber. It is an annual, sprawling plant that is native to North America . Sicyos angulatus , common name "bur cucumber", is an annual plant with a similar clinging vine growth but different-appearing flowers and seed pods.
For example, male inflorescence in plants often produce more flowers than females . Furthermore, pollen export and ultimately paternity, often increases with flower number, even for plants with hermaphroditic flowers. Retention of older flowers with no pollinator rewards can lead to increased pollinator visitation rate and increased pollen removal.
a sexual system for plants when female, hermaphrodite, and gynomonoecious plants coexist in the same population. [25]: 360 Monoicy: one of the main sexual systems in bryophytes. [18] In monoicy male and female sex organs are present in the same gametophyte. [19] Monoecy: a sexual system in which male and female flowers are present on the same ...
