Persimmon frost resistance

Diospyros kaki L. f.

Persimmon frost resistance is determined by species and varietal characteristics, ranging from -17 °C in oriental varieties to -30 °C in hybrid forms. This indicator is critical for breeding, rootstock selection, and expanding the cultivation geography of the crop.

In the reference 9 varieties crop Persimmon, where this is mentioned in the description.

To evaluate the frost resistance of persimmon, field observations of tissue condition after critical temperatures are used, along with laboratory analysis of cell sap concentration. Cultivated varieties of Diospyros kaki can withstand temperatures down to -17...-20 °C. The use of Diospyros virginiana in breeding allows achieving levels of up to -35 °C for the above-ground part, while hybrids involving it demonstrate resistance in the range of -26...-30 °C.

The frost resistance trait determines production strategies, including the choice of rootstock and the range of commercial cultivation. The root system of Diospyros virginiana is capable of tolerating soil freezing down to -15 °C, making it an effective rootstock for increasing the hardiness of Diospyros kaki varieties. High frost resistance also correlates with the duration of the natural dormancy period, which reduces the risk of damage during winter thaws.
