guttation
guttation The extrusion of water and sometimes salts from the aerial parts of plants, particularly at night when transpiration rates are low. Guttation may occur in plants that are less than about 10 m tall, where hydrostatic pressure is insufficient to prevent the flow of water into the xylem when the rate of transpiration is low. It also occurs in tropical plants, where high humidity inhibits transpiration. The process takes place through hydathodes.
