Abstract Electrolytic conductance was measured from acclimated and nonacclimated seedlings of apple, pear and citrus which were frozen and unfrozen. A close correlation between electrolytic conductance and survival was shown. A comparison was made between conductance and injury of apple and pear trees in the natural freeze of 1968-69 in Washington. Procedures are outlined for using conductance as a measure of cold tolerance among cultivars or treatments within the same cultivar. The use of T 10 and T 90 , which describes the transition range of injury, is outlined and described. Procedures are also outlined for following acclimation or deacclimation through the year and for determining freeze-injury from natural freezes.
