guttatie
Guttation is the exudation of liquid water from the edges or tips of plant leaves through specialized structures called hydathodes. It occurs mainly at night or in the early morning when soil moisture is high and transpiration is low, allowing root pressure to push water up through the xylem to the leaf margins.
The process involves root pressure driven by osmotic uptake of water by the roots. When stomata are
Guttation is often mistaken for dew, but it is plant-driven rather than a result of atmospheric condensation.
In general, guttation is a normal physiological process and not an indication of disease. It can reflect
