Parthenocarpy refers to the development of fruit without fertilization, resulting in seedless fruits. It occurs when the ovary of a flower grows into a fruit without the need for fertilization, which typically involves the fusion of male and female gametes.
Plant hormones play a role in promoting parthenocarpy. The application of certain hormones, such as auxins, gibberellins, and cytokinins, can induce parthenocarpy in some plants. These hormones stimulate the growth and development of the ovary, bypassing the requirement for fertilization, and ultimately leading to the formation of seedless fruit.
