    Or, with bisexual and at least one of male and female flowers on the same plant. [2] Protandrous: (of dichogamous plants) having male parts of flowers developed before female parts, e.g. having flowers that function first as male and then change to female or producing pollen before the stigmas of the same plant are receptive. [6]

    en.wikipedia.org/wiki/Marah_macrocarpa

    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

    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]

  5. Sexual selection in flowering plants - Wikipedia

    en.wikipedia.org/wiki/Sexual_selection_in...

    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.

  6. Monoecy - Wikipedia

    en.wikipedia.org/wiki/Monoecy

    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]

  7. Sexual system - Wikipedia

    en.wikipedia.org/wiki/Sexual_system

    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 ...

    Normally, this is done with plants by deactivating or removing male flowers from one population, taking advantage of time differences between male and female flowering, or hand pollinating. [ 4 ] In 1960, 99% of all corn , 95% of sugar beet , 80% of spinach , 80% of sunflowers , 62% of broccoli , and 60% of onions planted in the United States ...
