Abstract: Simulation tests of spring frost in strawberry (Fragaria ananassa) leaves and receptacles involved use of an artificial climate chamber. Leaves could tolerate intercellular freezing to some extent. At a tissue temperature of -6.4 ℃, leaves could survive 90-min freezing, but receptacles were not able to tolerate intercellular freezing. Receptacles resisted frost injury by maintaining a state of supercooling to avoid freezing. The proportion of receptacles injured was inversely related to decreased receptacle temperature, reaching 50% at -5.4 ℃. Full-blossom flowers and those with heavier fresh weight were susceptible to frost injury even at higher temperatures.
