Frost resistance of Asian pear

Pyrus pyrifolia (Burm. f.) Nakai var. culta (Mak.) Nakai

The frost resistance of the Asian pear is a limiting factor for its distribution, determined by the ability of tissues and generative organs to withstand critical sub-zero temperatures.

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

Representatives of Pyrus pyrifolia are characterized by poor winter hardiness in temperate climates, comparable to the level of Western European cultivars. Increased resistance is achieved through hybridization with the Ussurian pear, which allows some forms to withstand temperature drops down to –28…–30 °С.

Critical thresholds for branches and flower buds during the dormancy period are temperatures below –25…–30 °С. During the flowering phase, resistance decreases sharply, and damage to generative organs occurs even during spring frosts in the range of –1…–3 °С.
