Parthenocarpy is the condition in which fruits are developed without fertilization and due to this seed formation doesn’t take place. The fruits resemble the natural fruits only but they lack seeds.
Due to the parthenocarpy condition the fruit develop are seedless and this kind of fruits are known as Parthenocarpic fruits. Parthenocarpy word has been taken from German which means “Vergin Fruits”.
Cause’s of Parthenocarpy
These fruits may be produced due to:-
- Absence of Pollination
- Failure of Fertilization
- Zygotic sterility
Process of Parthenocarpy
During the cultivation of the desired species of the plant, parthenocarpy is introduced along with other plant hormones including Gibberellic acid. It results in the maturation of the ovary without the process of fertilization and produces bigger and pulpy fruits.
Examples of Parthenocarpy
Types of Parthenocarpy
Parthenocarpy has been categories into three parts :-
- Vegetative Parthenocarpy
- Stimulative Parthenocarpy
- Stenospermocary Parthenocarpy
Vegetative parthenocarpy usually takes place without pollination and due to the absence of pollination, no seeds are produced within the fruits.
Stimulative parthenocarpy is also like vegetative parthenocarpy in this also no pollination takes place and use plant growth regulator hormones and fertilize the fruit.
Stenospermocary is a unique type of parthenocarpy in which feralization does not take place and the seed begins to develop but it eventually aborts. Stenospermocary can be clearly seen in seedless grapes and watermelon.

Benefits of Parthenocarpy
- It Provides seedless flashy fruits
- It reduces the investment
- Its fruits are more healthy and can be achieved easily
- The Plant growth promotor is used are natural and help in the production of larger fruits.
- Parthenocarpy help in keeping insects and pest away from fruit
Advantages and Disadvantages of Parthenocarpy
|It is very Easy and famous process amongst the horticulturists||Chemically induced parthenocarpy fruits are harmful|
|Seedless Fruits are formed||The process need proper care|
|It helps in promoting jams and success industries||It makes fruit species sterile|

FAQ’s Regarding Parthenocarpy
What is Parthenocarpy?
Parthenocarpy is a natural and artificial process of producing fruits without fertilization. The fruit thus is produced seedless.
Name some Parthenocarpic fruits?
Banana, Grapes, Watermelon, Orange, Pear are some common example of Parthenocarpic fruits.
How does parthenocarpy occur in plants?
It can be occur by two types:
- Natural – Due to the absence of pollination, Failure of fertilization or Zygotic sterility.
- Artificial – By injecting plant growth hormones.
What is the difference between parthenocarpy and parthenogenesis?
Parthenogenesis may be defined as the development of a female gamete into a new individual without fertilization. While Parthenocarpy is the process in which fruits get produced without fertilization and hence they are seedless fruits.
Is Apple a Parthenocarpic fruit?
Apple comes into the category of false fruit because the apple develops from the thalamus. While the fruit develops from the ovary then it comes into true fruit.
