xenogamy

Definition

1. Noun:
   • Cross-fertilization in plants: "Xenogamy" refers to the fertilization of a flower by pollen from a flower on a different plant of the same species. This is a form of cross-pollination that ensures genetic diversity.

Usage Examples

• Noun:
  • Xenogamy is common in many flowering plants to prevent inbreeding. (Cross-fertilization between different plants of the same species is frequent.)
  • The farmer encouraged xenogamy by planting different varieties of corn nearby. (The farmer promoted cross-pollination between separate plants.)

Advanced Usage

• In botanical contexts: "Xenogamy" is specifically contrasted with "autogamy" (self-fertilization within the same flower) and "geitonogamy" (fertilization between flowers on the same plant).
  • Xenogamy requires a pollen vector, such as wind or insects, to transfer pollen between plants. (Cross-fertilization between different plants depends on external carriers.)

Variants and Related Words

• Xenogamous (adj): relating to or characterized by xenogamy.

  • The xenogamous system of this orchid ensures high genetic variability. (The cross-fertilizing system promotes diversity.)

• Xenogamously (adv): in a manner that involves xenogamy.

  • These trees reproduce xenogamously to avoid self-pollination. (They reproduce through cross-fertilization between different plants.)

Synonyms

• Cross-fertilization: the process of fertilizing a plant with pollen from a different plant.
• Allogamy: a broader term for fertilization involving gametes from different individuals, often used synonymously with xenogamy in plants.
