What is fruit production, without fertilisation called?
The formation of fruit without fertilisation is called parthenocarpy.
What is Fertilisation?
After pollination, a phase of sexual reproduction called fertilisation occurs in plants. The combination of the female and male gametes (ovum and pollen) to create a diploid zygote is known as fertilisation. It is a physical-chemical process that follows the pollination of the carpel.
In plants, generally after fertilisation, the ovule becomes a seed, and the ovary converts into fruit. In some cases, fruit can also be developed without the fertilisation process through parthenocarpy, and these fruits are known as parthenocarpic fruits.
What is Parthenocarpy?
The formation of fruit from an unfertilised egg is known as parthenocarpy. Either naturally or artificially can be done to obtain it. There are two distinct forms of parthenocarpy. These are listed below:
- Pollination is necessary for the stimulative parthenocarpy process to develop fruit. Seedless watermelon is an example of a stimulative parthenocarpy.
- Pollination is not necessary for the production of fruits through the vegetative parthenocarpy. Seedless cucumber is an example of vegetative parthenocarpy.
Hence, the fruit produced through this process is seedless in its nature. Some other examples of parthenocarpic fruits are pineapple, banana, cucumber, grape, watermelon, orange, grapefruit, pear, fig, etc.
Final Answer
The production of fruits without the process of fertilisation is called the parthenocarpy.
