Abstract
Changes in total sugars, reducing sugars, total N and protein N showed little relationship to changes in cold acclimation. Root and top moisture percentages decreased during the fall, the rates closely paralleling the increase in cold acclimation. It is postulated that a decrease in the cellular moisture, resulted in increased concentration of cellular solutes and closer spatial arrangement of water binding substances. Cold acclimation may have resulted from the higher bound water/free water ratio.
