Solution

The process of guttation takes place when the root pressure is high and the rate of transpiration is low.

Explanation:

The effect of root pressure is observable at night as well as the early morning when evaporation is low. Excess water gets collected in the form of droplets around special openings of veins near the tip of grass blades and leaves of many herbaceous parts of plants such as Tropaeolum, Balsam and grasses. Such water loss in its liquid phase is known as guttation.
