Question
Enumerate the process of guttation. How is it affected by root pressure?
✓

Answer

The process of exudation of liquid drops from the margins of the leaves through hydathodes is called guttation. Guttation is affected by root pressure in the following ways:
  1. When root pressure is high and transpiration is low, herbaceous plants may loose small quantities of liquid water in the form of drops.
  2. The rate of guttation increases with a decrease in root pressure Sed due to less absorption of water.
