Definition

1. Noun:
   • Self-fertilization in plants: The process in which a plant's ovum is fertilized by its own pollen, without the involvement of another individual. This is a form of reproduction within a single flower or hermaphroditic organism.

Usage Examples

• Noun:
  • Some plant species rely on autogamy to reproduce when pollinators are scarce.
  • The botanist studied the genetic implications of autogamy in the isolated population.

Advanced Usage

• "Obligate autogamy": A reproductive strategy where a species is exclusively self-fertilizing.

  • The species exhibits obligate autogamy, which limits its genetic diversity.

• "Facultative autogamy": The ability of a plant to self-fertilize but also capable of outcrossing.

  • The flower is capable of facultative autogamy, ensuring seed set even in the absence of cross-pollination.

Variants and Related Words

• Autogamous (adj): Relating to or characterized by autogamy.

  • The autogamous nature of the flower ensures consistent seed production.

• Geitonogamy (n): A related form of self-fertilization where pollen is transferred between different flowers on the same plant.

  • While not strictly autogamy, geitonogamy is another form of self-pollination.

Synonyms

• Self-pollination: The transfer of pollen from the anther to the stigma of the same flower or another flower on the same plant.
• Self-fertilization: The fusion of male and female gametes from the same individual.

Antonyms

• Allogamy: Cross-fertilization; fertilization involving gametes from different individuals.
• Xenogamy: Cross-pollination between flowers of different plants.
