In fact, you have observed a phenomenon called “guttation”, by which plants exude water from structures called ‘hydathodes” on margins or tips of leaf blades. Learn how your comment data is processed. • Guttation depends on root pressure while transpiration does not. Together with the grower, I want to achieve a final zero discharge by increasing plant resilience". The exudation takes place through groups of leaf cells called hydathodes. At night in some plants, root pressure causes guttation or exudation of drops of xylem sap from the tips or edges of leaves. B ) Transpiration . Always apply the Golden Rule of Watering—let the soil dry out before watering again, then water thoroughly—and then guttation will cease. ( Log Out /  Also, if you water in the morning, there will be less risk of guttation that if you water in the evening, as any excess moisture in the soil will have had time to be absorbed or to evaporate before the stomata shut down for the night.

Stomata are bean-shaped cells that open up to let the plant breathe and transpire. Maintenance videos for mechanical equipment. The drops discussed here aren’t pure water, but rather sap, and come from inside the leaf. Compounds can be lost from inside plants via: (i) active excretion to the external surface, such as excretion of lipophilic or hydrophilic compounds by glandular trichomes (Werker, 2000); (ii) excretion of inorganic solutes at tips and margins of leaves by guttation (root pressure induced); and (iii) leaching from damaged plant parts, such as leaf tips or margins or from intact plant tissues. The process is only possible in plants that are equipped with enlarged specialized stomata called hydathodes. Change ), You are commenting using your Twitter account.

The water gets accumulated in plant and creates a small root pressure. Adapted from an article originally published on November 23, 2015. The process of guttation occurs when the roots of a plant absorb water from the soil. Plant guttation is a fluid from xylem and phloem sap secreted at the margins of leaves from many plant species. Guttation • Guttation is the appearance of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses. Root pressure and guttation are common among most crop plants, yet the importance of this poorly studied feature of plant function is unknown. 3. Guttation causes is not generally harmful to the plant. This root pressure forces the water to exude through leaf tip, hydathodes or water glands and forms droplets. Cohesion: When water molecules stick to one another through cohesion, they fill the column in the xylem and act as a huge single molecule of water (like water in a straw). Guttation mostly occurs on leaf tips or edges. What is the main cause of guttation in plants? • Transpiration is a controlled process, whereas guttation is not. Guttation is the process of loss of water from the surface of leaves in the form of liquid drops. What is the difference between organic and mineral fertilizers? In a sense, guttation is Mother Nature’s way of allowing plants to relieve water pressure that can build up in their tissues under certain conditions. Guttation indicates that the tension between the cell wall and the cell content, or the turgor or cell tension is in order.
