10 Differences Between apomixis and parthenocarpy

Apomixis and Parthenocarpy: Understanding the Differences

Apomixis and parthenocarpy are two terms often used in the field of plant biology. While they both relate to reproductive processes in plants, they have distinct characteristics and applications. In this article, we will explore what apomixis and parthenocarpy are, provide examples, discuss their uses, and highlight their key differences.

What is Apomixis?

Apomixis refers to a type of reproduction in plants that does not involve the fusion of gametes. It is a form of asexual reproduction where embryos are produced without fertilization. The resulting offspring are genetically identical clones of the parent plant.

Examples of Apomixis:

1. Dandelion plants produce seeds through apomixis. The seeds are genetically identical to the parent plant and can germinate into new dandelion plants.

2. Citrus plants, such as oranges and lemons, also exhibit apomixis. Their seeds are formed without fertilization.

Uses of Apomixis:

1. Apomixis allows for the production of genetically identical offspring, which can be advantageous for plant propagation in agriculture. It ensures that desirable traits are maintained in the progeny.

2. It enables the rapid and efficient multiplication of plants without the need for sexual reproduction.

What is Parthenocarpy?

Parthenocarpy is a phenomenon in plants where fruits develop without fertilization. It is a form of asexual reproduction in which fruits are produced without the involvement of male gametes or pollination. The resulting fruits are seedless or contain undeveloped seeds.

Examples of Parthenocarpy:

1. Seedless varieties of grapes, such as Thompson seedless grapes, are a result of parthenocarpy. These grapes develop without the fusion of male and female gametes.

2. Bananas are also examples of parthenocarpic fruits. They do not require pollination for fruit set.

Uses of Parthenocarpy:

1. Parthenocarpic fruits have a longer shelf life as they do not contain fully developed seeds. This makes them more commercially viable.

2. Parthenocarpy can enhance fruit production in crops as it eliminates the need for pollination and seed formation.

Differences between Apomixis and Parthenocarpy:

Difference Area Apomixis Parthenocarpy
Reproduction Mechanism Asexual reproduction without fertilization Asexual reproduction without fruit fertilization
Seed Formation Seeds are formed without fertilization Fruits develop without fertilization, resulting in seedless or undeveloped seeds
Genetic Variation Offspring are genetically identical clones of the parent plant Offspring may show genetic variation due to the involvement of male gametes in pollination
Propagation Method Commonly used for plant propagation in agriculture Can be used to enhance fruit production
Natural Occurrence Apomixis occurs naturally in some plant species Parthenocarpy occurs naturally in some plant species
Seed Requirement Does not require the production of seeds for reproduction Seeds are not essential for fruit formation but can be present in seedless fruits
Pollination Not dependent on pollination Not dependent on pollination, but pollination can occur
Commercial Use Less commercially utilized due to limited crop variety More commercially utilized for seedless fruit production
Advantages Allows for the maintenance of desirable traits Enhances fruit quality and shelf life
Disadvantages Can lead to reduced genetic diversity Seedless fruits cannot produce viable seeds for propagation


In summary, apomixis and parthenocarpy are distinct reproductive processes in plants. Apomixis involves asexual reproduction without fertilization, resulting in genetically identical offspring. It is primarily utilized for plant propagation. Parthenocarpy, on the other hand, leads to fruit development without fertilization and is commonly used for commercial seedless fruit production. While both processes have their advantages and disadvantages, they serve different purposes in plant biology.

People Also Ask:

1. What is the significance of apomixis in agriculture?
Apomixis enables the production of genetically identical plants with desirable traits, making it valuable for plant propagation in agriculture and horticulture.

2. Can parthenocarpic fruits produce viable seeds?
No, parthenocarpic fruits do not contain fully developed seeds and are unable to produce viable seeds for propagation.

3. Are there any disadvantages of apomixis?
Apomixis can lead to reduced genetic diversity as it produces genetically identical offspring. This limits the ability to adapt to changing environmental conditions.

4. How does parthenocarpy benefit commercial fruit production?
Parthenocarpy allows for the production of seedless fruits, which have a longer shelf life and are more commercially desirable. It also eliminates the need for pollination, simplifying fruit production.

5. Can apomixis and parthenocarpy occur in the same plant species?
Yes, it is possible for a plant species to exhibit both apomixis and parthenocarpy, although they are genetically and mechanistically distinct processes.
