Parthenocarpy

Parthenocarpy (or stenospermocarpy) occasionally occurs as a mutation in nature; if it affects every flower, the plant can no longer sexually reproduce[citation needed] but might be able to propagate by apomixis or by vegetative means.

The seedless wild parsnip fruit are preferred by certain herbivores and so serve as a "decoy defense" against seed predation.

Seedlessness is seen as a desirable trait in edible fruit with hard seeds such as banana, pineapple, orange and grapefruit.

Parthenocarpy is also desirable in fruit crops that may be difficult to pollinate or fertilize, such as fig, tomato and summer squash.

In dioecious species, such as persimmon, parthenocarpy increases fruit production because staminate trees do not need to be planted to provide pollen.

Horticulturists have selected and propagated parthenocarpic cultivars of many plants, including banana, fig, cactus pear (Opuntia), breadfruit and eggplant.
