A root pressure of 1 to 2 atmospheres has been reported in a number of cases. The fundamental objection to the idea that root pressure plays any prominent part in the ascent of sap in plants lies in the fact that root pressure is usually negligible in plants of temperate regions during the summer where, in general, conditions of the soil rarely favours excessive absorption for any considerable length of time.
