In plant physiology, guttation is the exudation of liquid water, rather than vapour, from the margins or tips of leaves, forced out through specialised pores called hydathodes when root pressure pushes xylem sap upward faster than it can transpire, typically at night or in humid conditions. Takeda and Glenn's 1989 study of strawberry links hydathode anatomy to guttation and the plant's water status, showing that the droplets carry dissolved solutes along with water. The referent is a root-pressure-driven water loss through hydathodes, distinct from dew (which condenses from the air onto the leaf) and from stomatal transpiration.[1]
