Parthenocarpy: formation of fruit without fertilization. Parthenocarpic fruits are devoid of seeds, Eg. Banana
Gibberellin can induce the formation of seedless fruits but not through parthenocarpy but through stenospermocarpy
Stenospermocarpy: a biological phenomenon which induces seedless fruit formation in some fruits especially grapes. In stenospermocarpic fruits, normal pollination and fertilization is essential to ensure fruit formation. But during the course of fruit development spontaneous embryo abortion takes places and it leads to near seedless condition.
