Root Pressure The maximum root pressure that develops in plants is typically less than 0.2MPa, and this force for water movement is relatively small compared to the transpiration pull. Patients who have urticaria for more than 6 weeks are given the diagnosis of chronic urticaria.

Water flows into the xylem by osmosis, pushing a broken water column up through the gap until it reaches the rest of the column. During the periods of rapid transpiration particularly in midsummer, it has sometimes been observed that the cut end of a stump absorbs water, instead of exuding, if water is supplied at the cut surface.
