On succulents that have no leaves, like cactus, it may appear on their stems. This creates a pressure inside the plant, and the water is forced out through the hydathodes. Buying a spraying trolley: where do I start? Important Solutions 2858. The exudation takes place through groups of leaf cells called hydathodes. Plant guttation is a fluid from xylem and phloem sap secreted at the margins of leaves from many plant species. What is the added value of a unique concept? If the plant remains sitting in waterlogged soil, though, it could actually cause certain cells not just to leak sap, but to burst and die, leaving a corky growth called edema.

Guttation is most noticeable when transpiration is suppressed and the relative humidity is high, such as during the night. Under low transpiration and high soil moisture conditions, high root pressure of plants can secret water drops at the margin or tips of plant leaves through hydathodes, which is called guttation [15].
