The secretion of water onto the surface of
leaves through specialized pores, or
hydathodes. The process occurs most
frequently during conditions of high humidity
when the rate of transpiration is low. Drops
of water found on grass in early morning are
often the result of guttation, rather than
dew. Sometimes the water contains minerals in
solution, such as calcium, which leaves a
white crust on the leaf surface as it dries.
