In normal pollination, an auxin-producing system is activated which results in fruit-set, whereas in parthenocarpy the unfertilized ovary contains sufficient auxin—either due to natural production or artificial application.

It is difficult to distinguish between the role of auxin in fruit-set and its role in the actual growth of the fruit. Assuming that such a distinction can be made, it can be said that in general there are two phases of auxin production by young fruit. In the earliest stages of growth, auxin production is essentially carried out in the ovary tissue surrounding the young embryo (Gustafson, 1939), whereas in later.
