About describe parthenocarpy & polyembryony
Apomixis is a form of asexual reproduction in which seeds are developed without fertilization. Parthenocarpy is the development of fruit without fertilization.
One or more embryos are formed within one seed. It is a modified form of reproduction in which gametes fuse without formation of seeds.
Pineapples and figs, which occur naturally, are also examples of parthenocarpy. Also Read: Parthenocarpy, Formation, Parts, and Types of Frits.
What is Parthenocarpy and Apomixis – Toppr-guides
Parthenocarpy is being increasingly used to generate seedless fruit varieties today due to the quality and safety of the drawn-out grow span. Parthenocarpy results when the ovary is stimulated by wind pollination, without the necessity of fertilization, from the first bloom blossom.
Induced Polyembryony experimentally induced. According to Webber, polyembryony is classified into three different types: Cleavage Polyembryony: Ashley, the case of this type is such that a single fertilized egg gives rise to multiple embryos.

If a fruit originates in the absence of the influence of pollination, it is considered vegetative parthenocarpy (automatic), such as strawberries.
It is a commercially important process in which seedless fruit is formed without fertilisation, e. Polyembryony The occurrence of more than one embryo in a seed is known as polyembryony, e.
The formation of fruits without fertilization is the seed stage of the parthenocarpy process. It can be affected by the growth regulators, such as auxins and gibberellins.
parthenocarpy: formation of fruits without fertilization: polyembryony: occurrence of multiple ovules within a single ovule: what is apomixis. Have you ever heard of certain insects or reptiles that occasionally reproduce without fertilization of male and female gametes.
