parthenocarpy

Thân thiện

A gardener examines a seedless cucumber grown through parthenocarpy.

Definition

Noun: 1. (Botany) The development of a fruit without fertilization or seeds. This is a biological process where a fruit matures and grows even though the ovules (which would normally become seeds) have not been fertilized by pollen. The resulting fruit is typically seedless.

Usage

The term is used in scientific, agricultural, and botanical contexts to describe a specific type of fruit development. * As a subject: "Parthenocarpy is a desirable trait in many commercial fruit crops." * As an object: "Some plant species exhibit natural parthenocarpy." * With a modifier: "Induced parthenocarpy can be triggered by applying plant hormones."

Examples

• Bananas and many varieties of oranges are common examples of parthenocarpy, as they produce fruit without seeds.
• Growers sometimes use hormone sprays to induce parthenocarpy in tomatoes to ensure fruit set even in poor pollination conditions.
• The study focused on the genetic mechanisms behind parthenocarpy in cucumber plants.

Advanced Usage

• Facultative Parthenocarpy: Refers to plants that can produce fruit either with or without fertilization, often depending on environmental conditions.
• Stenospermocarpy: This is a related but distinct concept where fertilization occurs, but the seeds abort or fail to develop fully, resulting in a seedless fruit (e.g., seedless watermelons). It is important to distinguish this from true parthenocarpy, where fertilization does not occur at all.

Variants and Related Words

• Parthenocarpic (adjective): Describing a fruit or plant that develops without fertilization.
  • Example: They cultivated a parthenocarpic variety of eggplant.
• Parthenogenesis: A related but different biological process in animals where an embryo develops from an unfertilized egg cell.

Synonyms

• Seedless fruit development (This is a descriptive phrase, not a direct scientific synonym.)
• Virgin fruit development (An older, less common descriptive term.)

Antonyms

• Zygocarpy: (A technical term) The development of fruit following normal fertilization.
• Fertilization-dependent fruit development.
