Separated sorption isotherms and sorption hysteresis a.
Cell wall sorption isotherms (o) and capillary water isotherms (x). The y-axis is cut, but the capillary moisture content at water saturation was 0.792 g g-1 with standard deviation 0.215 g g-1. Note that moisture contents at water-saturation are placed at -10° J kg-1. b. Absolute sorption hysteresis evaluated from the data in a.
