Apricot frost resistance

Prunus armeniaca L.

A biological trait defined by the ability of wood and generative buds to withstand extremely low temperatures during the dormancy period.

In the reference 19 varieties crop Apricot, where this is mentioned in the description.

Apricot frost resistance is characterized by a critical temperature threshold at which tissue damage occurs and is evaluated using artificial freezing methods or a scoring scale under field conditions. A key feature of the crop is the short duration of deep dormancy in generative buds, which can withstand down to –30…–35 °C, but lose resistance during mid-winter thaws and perish at –13…–15 °C.

In breeding and cultivar testing, this parameter is considered in conjunction with winter hardiness, which includes the tree's response to temperature fluctuations and late spring frosts. A limiting factor for fruit bearing is sensitivity to thaws, which trigger early bud development, requiring the selection of cultivars with a prolonged dormancy period and late flowering dates.
