Parthenocarpy
The formation of fruits without fertilization is called parthenocarpy. Such fruits are either seedless or non-viable seeds.
Parthenocarpy is of two types:
(1) Natural parthenocarpy: When seedless fruits are produced without any special treatment from the ovaries in the absence of pollination and fertilization, the phenomenon is called natural parthenocarpy. e.g., Grapes, Banana, Pineapple and Noval oranges.
(2) Induced parthenocarpy: When seedless fruits are produced by spraying the flowers with either water extract of pollen grains or growth promoting hormones such as Indole acetic acid (IAA), Naphthalene acetic acid (NAA), Gibberellic acid (GA), etc. the phenomenon is called induced parthenocarpy. e.g., Tomato, Black berry, Fig, Lemon, Apple, Orange, Pear. etc.
