Persimmon parthenocarpy

Diospyros kaki L. f.

The biological ability of Diospyros kaki to set fruit without fertilization, which allows for the production of seedless fruit crops without the need for pollinator varieties.

In the reference 4 varieties crop Persimmon, where this is mentioned in the description.

Parthenocarpy in Diospyros kaki determines not only the possibility of fruiting in the absence of pollinators or under conditions unfavorable for insects, but also the commercial quality of the yield. Fruits set without fertilization often differ in size and taste from those formed with seeds, as in many cultivars the presence of seeds affects flesh browning, astringency levels, and sugar content.

The evaluation of parthenocarpic ability in breeding is conducted by isolating flowers and subsequently analyzing the percentage of fruit set on such branches. The stability of this trait may vary depending on the cultivar, annual weather conditions, and the level of insolation. Despite the capacity for parthenocarpy, cross-pollination in many persimmon cultivars contributes to an increase in fruit weight and changes in their consumer characteristics, which must be taken into account when planning orchard layouts.
