- (private-note)Xylem freezebolism (and drought bolism) related to conduit diameter ability to recover was related to diameter in droughtbolism but not freezebolism cooled (and warmed) at 0.3oCmin-1 Held at desired temperature (-1.5, -2.5, -5, -11) for 3 hours before warming There was further loss in hydraulic conductivity 24 hours after freezing and thawing from -5 and -11, while the lower temperatures showed recovery. interpreted the diameter effect as possibly because only the larger conduits freeze, and embolism occurs on freezing. Recovery differences could be because drought refilling occurs under +ve pressure (with smaller conduits needing more pressure to refill), and freezing refilling occurs under -ve pressure (with larger conduits having such huge bubbles that they're hard to refill) "Such large emboli have been reported to persist to an extent proportional to their diameter in xylem conduits (hammel 1967; Just and Sauter 1991) and in glass capillaries (Ewers 1985) and may trigger runaway embolism leading to catastrophic xylem dysfunction (Tyree and Sperry 1988) High resistance to flow in narrow conduits might make root pressure insufficient to refill them.
