Fig. 1

Time series of one freezing experiment repetition with a Pterocarya fraxinifolia branch during cold-hardy stage. Diameter shrinkage to branch diameter percentage (DS) is shown. The terminology used regarding total diameter shrinkage (DStotal), reversible diameter shrinkage (DSreversible), and irreversible diameter shrinkage (DSirreversible) is introduced. Gray area refers to the period when xylem sap is frozen
