The exudation of drops of water from the leaves of some vascular plants as a result of root pressure. See more. Root pressure can result in the loss of liquid water from the leaves during times of low transpiration. When there is a high soil moisture level, water will enter plant roots, because the water potential of the roots is lower than in the soil solution. Excessive transpiration during dry seasons can result to plant wilting. However, some water may be exuded in liquid form, a process called guttation. When soil moisture is very high, water will enter the plant roots because the water potential of the roots is lower than that of the surrounding soil. • Transpiration is a controlled process, whereas guttation is not.

Guttation By Halala Rahman Qadir 2. 7. Drops of water appear along the margins of leaves, usually as a result of exudation through special glands known as hydathodes. Effect of root pressure is observable at night and early morning when evaporation is low and excess water collects in the form of droplets near the tip of leaves of many herbaceous plants. Guttation is the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses. It takes water and uses photosynthesis for growth. 3). In both transpiration and guttation water is lost through specialized pores. It occurs in the xylem of some vascular plants, when the soil moisture level is high either at night or when transpiration is low during the day. The liquid of guttation comprises a variety of inorganic and organic compounds which mainly include potassium and sugars. I'm hoping that you all understand what transpiration is.
